An Ad-Hoc Wireless Network Architecture for Face-to-Face Mobile Collaborative Applications

摘要

An architecture for building an ad-hoc wireless network is presented in which various face-to-face, peer-to-peer collaborative applications function simultaneously and the interconnections between group members are highly dynamic and self-organizing. To illustrate how the architecture implements communication, examples of client-server and point-to-point communication are given. An interconnection architecture of a Mobile Computer Supported Collaborative Learning (MCSCL) environment is analyzed in detail. Its communication protocols are showed with sequence diagrams. The paper concludes with an evaluation of the architecture's performance.
