This paper proposes and tests, through a series of structured multi-disciplinary design activities, a “Concept Design Stages Protocol” (CDS Protocol) to structure project initiation, to attain smoother collaboration and greater consensus among multi-disciplinary project teams.

A collaborative approach from the outset is imperative for project success, especially when considering multi-disciplinary teams in the architecture, engineering and construction (AEC) industry. However, involving different disciplines hinders communication paths and affects informed decision-making.

Based on these findings, the research demonstrates that the CDS Protocol provides a solid foundation to aid in the optimal implementation of collaborative design, and with particular regard to multi-disciplinary working.

The research demonstrates the potential for significant improvement in the optimisation of the conceptual design stages, with positive implications for time, communication and whole-team engagement.

The purpose of this paper is to present a concept of the protocol for public registries based on blockchain. New database protocol aims to use the benefits of blockchain technologies and ensure their interoperability.

This paper is framed with design science research (DSR). The primary method is exaptation, i.e. adoption of solutions from other fields. The research is looking into existing technologies which are applied here as elements of the protocol: Name-Value Storage (NVS), Berkley DB, RAID protocol, among others. The choice of NVS as a reference technology for creating a database over blockchain is based on the analysis and comparison with two other similar technologies Bigchain and Amazon QLDB.

The proposed mechanism allows creating a standard database over a bundle of distributed ledgers. It ensures a blockchain agnostic approach and uses the benefits of various blockchain technologies in one ecosystem. In this scheme, blockchains play the role of journal storages (immutable log), whereas the overlaid database is the indexed storage. The distinctive feature of such a system is that in blockchain, users can perform peer-to-peer transactions directly in the ledger using blockchain native mechanism of user access management with public-key cryptography (blockchain does not require to administrate its database).

This paper presents a new method of creating a public peer-to-peer database across a bundle of distributed ledgers.

The paper is an excerpt from a more comprehensive study by the Florida Department of Environmental Protection comparing the technical elements of offset projects in forestry, agriculture, and waste management, as well as some miscellaneous project types. The authors compare and contrast design elements of three specific offset projects: afforestation/reforestation, manure management, and landfill gas capture. The technical review for each offset project is concluded with a look at the potential applicability for that project in Florida in the context of the protocols evaluated.

Offset projects that may be employed in Florida are first broken up into comparable design elements specific to the selected offset project type. Focusing on the design elements, a discussion of the similarities and differences among the protocols for each offset project is presented. Each section begins with general findings then moves on to assessments of the detailed design elements. Finally, the project's general applicability to Florida is considered, highlighting specific strengths of particular protocols from the analysis of the design elements.

Protocols tend to vary from highly specific requirements to a more general set of recommendations. Interestingly, no one program's set of protocols is the most opportunistic for Florida, but rather various protocols may have distinctive strengths depending on the project type.

Many comparative studies of offset protocols evaluate protocols in the context of program‐level policies. This study uniquely values the technical details in the protocols and does not consider policy or program‐level issues.

Cooperative control of a group of unmanned aerial vehicles (UAVs) is an important area of research. The purpose of this paper is to explore multi-UAV control in the framework of providing surveillance of areas of interest with automatic loss detection and replacement capabilities.

The research is based on the concept of the multi-agent system. The authors present the framework of the multi-agent and protocol design for monitoring the network of a group of UAVs.

If one or more UAVs which is conducting a high priority surveillance task is lost, the system can self-arrange for another UAV to replace the lost UAV and continue to execute its task. This research provides an excellent design protocol for UAV loss detection and replacement scheme.

One of the major limitations of this research is that we have only two types of priority levels, high or low. If the priority is more than two levels, for example, high priority 1, high priority 2, or high priority 3, the replacement has not yet been implemented.

This paper contributes to the following two aspects of the scientific knowledge. The first contribution is the design of an agent model which jointly considers system architecture, communication, control logic and target monitoring. The second contribution includes the decentralized and automatic UAV loss detection and replacement algorithm.

The purpose of this paper is to develop a step-by-step procedure, referred to as transaction formalism protocol (TFP) that the transaction development personnel will use to formalise transactions (communications) in the domain of infrastructure management. The protocol is developed at two levels of abstraction: TFP specification and TFP tool. This paper presents the TFP specification in detail and introduces the TFP tool briefly. The specific focus of this paper is on the development process of the protocol specification.

A four-step approach is used to develop the TFP; including, identify and select existing standards, benchmark standards, link and build on these standards, and develop TFP. To develop the protocol, the function modelling standard, integration definition function modelling (IDEF0) is used. The IDEF0 treats each step of the protocol as a function.

The TFP specification and TFP tool are developed using the proposed methodology. The TFP specification specifies inputs, controls, mechanisms, tools/techniques, and outputs required in each step, whereas the TFP tool defines forms for each step of the protocol that the transaction development personnel will use to define transactions in the domain of infrastructure management.

The development of the TFP would enable the transaction development personnel (including transaction analysts, transaction designers, software developers, process modellers, and industry experts) to formalise transactions effectively and efficiently for the development of ICT-based collaboration systems.

The proposed protocol incorporates shortcomings of existing standards. In contrast to other design standards that focus on either design or design cum implementation of the work processes and communications, the proposed TFP includes transaction monitoring and improvements in addition to the design and implementation of communications. Unlike other standards, the TFP is a detailed step-by-step procedure to ease its usability and understandability.

This paper is a review of a number routing protocols in the internet of vehicles (IoV). IoV emphasizes information interaction among humans, vehicles and a roadside unit (RSU), within which routing is one of the most important steps in IoV network.

In this paper, the authors have summarized different research data on routing protocols in the IoV. Several routing protocols for IoV have been proposed in the literature. Their classification is made according to some criteria such as topology-based, position-based, transmission strategy and network structure. This paper focuses on the transmission strategy criteria. There exist three types of protocols that are based on this strategy: unicast protocol, broadcast protocols and multicast protocols. This later type is classified into two subclasses: geocast and cluster-based protocols. The taxonomy of the transmission strategy is presented in this study. We discuss the advantages and disadvantages of each type with a general comparison between the five types.

The authors can deduce that many challenges are encountered when designing routing protocols for IoV.

A simple and well-explained presentation of the functioning of the IoV is provided with a comparison among each categories of protocols is well presented along with the advantages and disadvantages of each type. The authors examined the main problems encountered during the design of IoV routing protocol, such as the quick change of topology, the frequent disconnection, the big volume of data to be processed and stored in the IoV, and the problem of network fragmentation. This work explores, compares existing routing protocols in IoV and provides a critical analysis. For that, the authors extract the challenges and propose future perspectives for each categories of protocols.

Describes the NISO circulation interchange protocol (NCIP) and some of the design decisions that were made in developing it. When designing a protocol of the scale and scope of NCIP, certain decisions about what technologies to employ need to be made. Often there are multiple competing technologies that can be employed to accomplish the same functionality, and there are both positive and negative reasons for the choice of any particular one. Focuses specifically on the areas on which the protocol would be supported. Gives particular emphasis to the decision to choose XML as the encoding technology for the protocol messages. One of the main design goals for NCIP was to try to strike the appropriate balance between ease of implementation and providing appropriate functionality. This functionality includes that needed to support both application areas that the committee could anticipate would use the protocol in the short term, and new applications that might be developed in the future.

The purpose of this paper is to design a hierarchical routing protocol. Wireless sensor network (WSN) consists of a set of miniature sensor nodes powered by a low-capacity energy battery. This limitation requires that energy is used in an efficient way and kept as long as possible to allow the WSN to accomplish its mission. Thus, energy conservation is a very important problem facing researchers in this context. Because sending and receiving messages is the activity that consumes the most energy in a WSN, so when designing routing protocols, this problem is targeted specifically. The aim of this paper is to propose a solution to this problem by designing a hierarchical routing protocol.

The authors started by designing a protocol called efficient energy-aware distributed clustering (EEADC). Simulation result showed EEADC might generate clusters with very small or very large size. To solve this problem, the authors designed a new algorithm called fixed efficient energy-aware distributed clustering (FEEADC). They concluded from the simulation result that cluster-heads (CHs) far away from the base station die faster than the ones closer to it. To remedy this problem, they propose multi-hop fixed efficient energy-aware distributed clustering (M-FEEADC). It is based on a new fixed clustering mechanism, which aims to create a balanced distribution of CHs. It uses data aggregation and sleep/wakeup techniques.

The simulation results show a significant improvement in terms of energy consumption and network lifetime over the well-known low-energy adaptive clustering hierarchy and threshold-sensitive energy-efficient protocols.

The authors propose M-FEEADC. It is based on a new fixed clustering mechanism, which aims to create a balanced distribution of CHs. It uses data aggregation and sleep/wakeup techniques.

A wireless body area network (WBAN) plays a crucial role in the health-care domain. With the emergence of technologies like the internet of things, there is increased usage of WBAN for providing quality health services. With wearable devices and sensors associated with human body, patient’s vital signs are captured and sent to doctor. The WBAN has number of sensor nodes that are resource constrained. The communications among the nodes are very crucial as human health information is exchanged. The purpose of this paper aims to have Quality of Service (QoS) with energy aware and control overhead aware. Maximizing network lifetime is also essential for the improved quality in services. There are many existing studies on QoS communications in WBAN.

In this paper, with the aim of energy-efficient WBAN for QoS, a cross-layer routing protocol is designed and implemented. A cross-layer routing protocol that is ad hoc on-demand distance vector (AODV)-based, energy and control overhead-aware (AODV-ECOA) is designed and implemented for energy-efficient routing in WBAN. The cross-layer design that involves multiple layers of open systems interconnection reference model, which will improve energy efficiency and thus QoS.

Implementation is simulated using the network simulator tool, i.e. NS-2. The proposed cross-layer routing protocol AODV-ECOA shows least bandwidth requirement by control packets, leading to less control overhead, highest packet delivery ratio and energy efficiency. The experimental results revealed that AODV-ECOA shows better performance over existing protocols such as AODV and POLITIC.

An efficient control overhead reduction algorithm is proposed for reducing energy consumption further and improves performance of WBAN communications to realize desired QoS.

Internet of Things (IoT) is an up-and-coming conception that intends to link multiple devices with each other. The aim of this study is to provide a significant analysis of Green IoT. The IoT devices sense, gather and send out significant data from their ambiance. This exchange of huge data among billions of devices demands enormous energy. Green IoT visualizes the concept of minimizing the energy consumption of IoT devices and keeping the environment safe.

This paper attempts to analyze diverse techniques associated with energy-efficient protocols in green IoT pertaining to machine-to-machine (M2M) communication. Here, it reviews 73 research papers and states a significant analysis. Initially, the analysis focuses on different contributions related to green energy constraints, especially energy efficiency, and different hierarchical routing protocols. Moreover, the contributions of different optimization algorithms in different state-of-the-art works are also observed and reviewed. Later the performance measures computed in entire contributions along with the energy constraints are also checked to validate the effectiveness of entire contributions. As the number of contributions to energy-efficient protocols in IoT is low, the research gap will focus on the development of intelligent energy-efficient protocols to build up green IoT.

The analysis was mainly focused on the green energy constraints and the different robust protocols and also gives information on a few powerful optimization algorithms. The parameters considered by the previous research works for improving the performance were also analyzed in this paper to get an idea for future works. Finally, the paper gives some brief description of the research gaps and challenges for future consideration that helps during the development of an energy-efficient green IoT pertaining to M2M communication.

To the best of the authors’ knowledge, this is the first work that reviews 65 research papers and states the significant analysis of green IoT.
