Abstract

Purpose

The purpose of this paper is to develop a model for the use of mobile computing in the management of on‐site construction information and communication.

Design/methodology/approach

The research strategy contains three steps: a pilot study for the first stage, a survey that investigated the information needs of particular users and the nature of on‐site information, and finally the development of a model and the validation and evaluation by operational scenarios.

Findings

The developed model explores how mobile computing can be used on construction sites to manage on‐site information. This model, firstly, identifies the key factors of mobile computer, wireless network, mobile application, construction personnel, construction information, and construction site; secondly it describes the relationships and interactions among these factors. Based on the model, the selection process for mobile computing strategy includes the clarification of information management process, the creations of overview for mobile computing solution, the identification of mobile computing strategy, and the selection of appropriate mobile computing technology.

Originality/value

The developed model explores the general concepts and the internal relationships at the two areas of mobile computing and construction site information management. The application of the model can help users to select mobile computing strategies for managing on‐site construction information based on the characteristics of their projects.

Abstract

Purpose

The purpose of this conceptual paper is to explore the meaning of cloud computing for mobile communication. The paper answers the question “what is mobile cloud computing?” and how is it related to the generic cloud computing concept?

Design/methodology/approach

This is an explanatory conceptual paper, based on literature review and exploring potential use cases, focused on the use of mobile cloud for service, platform or infrastructure access. The authors exclude the discussion of the traditional cloud concept in back office processes of telecom operators, and service providers.

Findings

Where cloud computing is focused on pooling of resources, mobile technology is focused on pooling and sharing of resources locally enabling alternative use cases for mobile infrastructure, platforms and service delivery. The paper discusses relevant concepts and offers examples of use cases.

Research limitations/implications

The value of mobile cloud solutions is not yet explicit, but needs further attention. Research should focus on the relation between mobile cloud computing, platforms and eco systems. From a user perspective the willingness to share pooled resources needs further attention.

Practical implications

Mobile cloud computing offers the possibility that disruptive applications might impact the mobile eco system; reinforcing or weakening business models of core players like handset providers, telecom operators, and service providers.

Originality/value

A lot of attention is paid to cloud computing and to platform discussions, papers on mobile cloud are scarce. This paper offers the current state of the art and a research outlook.

Abstract

Rather than organize as traditional firms, many of today’s companies organize as platforms that sit at the nexus of multiple exchange and production relationships. This chapter considers a most basic question of organization in platform contexts: the choice of boundaries. Herein, I investigate how classical economic theories of firm boundaries apply to platform-based organization and empirically study how executives made boundary choices in response to changing market and technical challenges in the early mobile computing industry (the predecessor to today’s smartphones). Rather than a strict or unavoidable tradeoff between “openness-versus-control,” most successful platform owners chose their boundaries in a way to simultaneously open-up to outside developers while maintaining coordination across the entire system.

Abstract

Mobile devices have received much research interest in recent years. Mobility raises new issues such as more dynamic context, limited computing resources, and frequent disconnections. A middleware infrastructure for mobile computing must handle all these issues properly. In this project we propose a middleware, called 3DMA, to support mobile computing. We introduce three requirements, distribution, decoupling and decomposition as central issues for mobile middleware. 3DMA uses a space based middleware, which facilitates the implementation of decoupled behavior and support for disconnected operation and context awareness. This is done by defining a set of “workers” which are able to act on the users behalf either: to reduce load on the mobile device, and/or to support disconnected behavior. In order to demonstrate aspects of the middleware architecture we then consider the development of a commonly used mobile application.

Abstract

Purpose

With the continuous technological development of automated driving and expansion of its application scope, the types of on-board equipment continue to be enriched and the computing capabilities of on-board equipment continue to increase and corresponding applications become more diverse. As the applications need to run on on-board equipment, the requirements for the computing capabilities of on-board equipment become higher. Mobile edge computing is one of the effective methods to solve practical application problems in automated driving.

Design/methodology/approach

In this study, in accordance with practical requirements, this paper proposed an optimal resource management allocation method of autonomous-vehicle-infrastructure cooperation in a mobile edge computing environment and conducted an experiment in practical application.

Findings

The design of the road-side unit module and its corresponding real-time operating system task coordination in edge computing are proposed in the study, as well as the method for edge computing load integration and heterogeneous computing. Then, the real-time scheduling of highly concurrent computation tasks, adaptive computation task migration method and edge server collaborative resource allocation method is proposed. Test results indicate that the method proposed in this study can greatly reduce the task computing delay, and the power consumption generally increases with the increase of task size and task complexity.

Originality/value

The results showed that the proposed method can achieve lower power consumption and lower computational overhead while ensuring the quality of service for users, indicating a great application prospect of the method.

Abstract

Purpose

The distant data centre-centric Internet of Things (IoT) systems face the latency issue especially in the real-time-based applications, such as augmented reality, traffic analytics and ambient assisted living. Recently, Fog computing models have been introduced to overcome the latency issue by using the proximity-based computational resources, such as the computers co-located with the cellular base station, grid router devices or computers in local business. However, the increasing users of Fog computing servers cause bottleneck issues and consequently the latency issue arises again. This paper aims to introduce the utilisation of Mist computing (Mist) model, which exploits the computational and networking resources from the devices at the very edge of the IoT networks.

Design/methodology/approach

This paper proposes a service-oriented mobile-embedded Platform as a Service (mePaaS) framework that allows the mobile device to provide a flexible platform for proximal users to offload their computational or networking program to mePaaS-based Mist computing node.

Findings

The prototype has been tested and performance has been evaluated on the real-world devices. The evaluation results have shown the promising nature of mePaaS.

Originality/value

The proposed framework supports resource-aware autonomous service configuration that can manage the availability of the functions provided by the Mist node based on the dynamically changing hardware resource availability. In addition, the framework also supports task distribution among a group of Mist nodes.

Abstract

Purpose

Cloud computing becomes mobile when a mobile device tries to access the shared pool of computing resources provided by the cloud, on demand. Mobile applications may enrich their functionality by delegating heavy tasks to the clouds as the remote processing and storage have become possible by adding asynchronous behavior in the communication. However, developing mobile cloud applications involves working with services and APIs from different cloud vendors, which mostly are not interoperable across clouds. Moreover, by adding asynchronicity, mobile applications must rely on push mechanisms which are considered to be moderately reliable, and thus not recommended in scenarios that require high scalability and quality of service (QoS). To counter these problems, and the purpose of this paper, is to design a middleware framework, Mobile Cloud Middleware (MCM), which handles the interoperability issues and eases the use of process‐intensive services from smartphones by extending the concept of mobile host.

Design/methodology/approach

MCM is developed as an intermediary between the mobile and the cloud, which hides the complexity of dealing with multiple cloud services from mobiles. Several applications are presented to show the benefits of mobiles going cloud‐aware. Moreover, to verify the scalability of MCM, load tests are performed on the hybrid cloud resources using well known load balancing mechanisms like HAProxy and Tsung.

Findings

From the study it was found that it is possible to handle hybrid cloud services from mobiles by using MCM. The analysis demonstrated that the MCM shows reasonable performance levels of interaction with the user, thus validating the proof of concept. Moreover, MCM decreases the effort in developing mobile cloud applications and helps in keeping soft‐real time responses by using its asynchronous approach.

Originality/value

MCM fosters the utilization of different types of cloud services rather than the traditional mobile cloud services based on data synchronization. By offloading heavy tasks to the clouds, the framework extends the processing power and storage space capabilities of the constrained smart phones. The applications mentioned in the paper bring an added value by being success stories for mobile cloud computing domain in general.

Abstract

Purpose

Context‐aware mobile computing extends the horizons of the conventional computing model to a ubiquitous computing environment that serves users at anytime, anywhere. To achieve this, mobile applications need to adapt their behaviors to the changing context. The purpose of this paper is to present a generalized adaptive middleware infrastructure for context‐aware computing.

Design/methodology/approach

Owing to the vague nature of context and uncertainty in context aggregation for making adaptation decisions, the paper proposes a fuzzy‐based service adaptation model (FSAM) to improve the generality and effectiveness of service adaptation using fuzzy theory.

Findings

By the means of fuzzification of the context and measuring the fitness degree between the current context and the predefined optimal context, FSAM selects the most suitable policy to adopt for the most appropriate service. The paper evaluates the middleware together with the FSAM inference engine by using a Campus Assistant application.

Originality/value

The paper is of value in presenting a generalized adaptive middleware infrastructure for context‐aware computing and also comparing the performance of the fuzzy‐based solution with a conventional threshold‐based approach for context‐aware adaptation.

Abstract

Mobile agent, as a new mobile computing technology, has been applied to various parallel and distributed computing problem solutions. Several mobile agent systems have been built to drive the agents following a platform dependant scheme, and some formal approaches have been proposed to describe mobile agents’ behaviors or properties for respective purposes. However, there remains a lack of a standard approach to describing a mobile agent algorithm and its semantics from the viewpoint of a practical program, which makes it difficult to specify an algorithm unambiguously and verify its correctness formally. This paper proposes a practical approach to overcome that difficulty by defining a script language and associated mechanisms to specify and verify mobile agent algorithms. The language, called SMAL, can describe mobile agent’s behaviors clearly due to its explicitly defined semantics. Based on the semantics, a transformation function for converting the specified algorithm to its equivalent specification in Mobile UNITY, a well‐known mobile computation formal approach for correctness verification, is presented. Formal verification of the algorithms can be accomplished based on the UNITY‐logic rules.
