This special issue of the International Journal of Pervasive Computing and Communications (IJPCC) is dedicated to four best papers carefully chosen from those accepted for presentation at the 12th Mobile Computing Workshop which was held in Taichung, Taiwan, 2006. This workshop serves as a forum for academic and industrial researchers and practitioners to exchange results, new ideas and experiences in all aspects of mobile computing.

The first paper on “Adaptive attenuation factor model for localization in wireless sensor networks” presents an adaptive localization algorithm that can dynamically adjust the ranging function to effectively estimate the locations of sensor nodes. The second paper on “An OSA service capability server for mobile services” presents an open service access (OSA) architecture that supports the network capabilities to the application servers. Through the modularized design of service capability servers, the OSA service deployment can be effectively sped up. The third paper on “An improved efficient performance design with multiple channels and bandwidth allocation strategy for mobile ad hoc networks” presents three methods to solve the problems associated with performance improvement in the multiple channel MAC protocol. The fourth paper on “Hierarchical data gathering schemes in wireless sensor networks” presents efficient data gathering schemes to reduce the energy consumption by adopting a hierarchical grid structure and scheduling redundant nodes in a grid into sleeping mode.

We are grateful to the authors for their contributions, to the referees for their hard work ensuring that all the papers that appear in this special issue have passed the most rigorous quality test. We wish to express our gratitude to Dr An-Chi Liu, the Honorary Chair of 2006 Mobile Computing and Dr Minyi Guo, University of Aizu, Japan, for their assistance with this special issue. Also, we would like to express our thanks to Dr Laurence T. Yang, the Editor-in-Chief of this journal, for offering this special issue.
