SUPPORTING GROUP-ORIENTED MOBILE SERVICES
Upkar Varshney · Journal of the Association for Information Systems · 2003
The emerging mobile services, including mobile commerce, have received considerable interest among researchers, developers, service providers, and users.Some of these mobile services will require group communications among mobile users.An efficient way to support this requirement is by using wireless multicast, where group connectivity among users is maintained and the information exchange is performed by the underlying networking infrastructure.In this paper, multicast requirements of mobile services under varying levels of connectivity are addressed.More specifically, the design and operation of three protocols for supporting multicast transactions is presented.Since these protocols could lead to different response time and transaction completion probabilities, performance evaluation under different connectivity and protocol conditions has been performed.These results can be used to select one or more multicast protocol(s) for grouporiented mobile applications.
