A Service-Oriented Design for Controlling Multimedia Sessions over Stand-Alone MANETs

Distributed multimedia applications over mobile ad hoc network have a great potential in various scenarios. However, establishing ad hoc multimedia sessions is not simple given that ad hoc nodes are highly dynamic and resource-limited. For session control, the conventional SIP is not applicable since using a particular mobile endpoint as a server is unrealistic. Recently, several proposals on extension of SIP have been introduced but most of reported results are in term of simulation statistics. In this study, we instead implement a real-world testbed for the proposed framework. Taking into account node mobility and route instability, we initiate a fully distributed and service-oriented design. In the strategy, routing information messages are exploited to convey user identity data. At the same time, each node maintains a compound routing table that contains both route data and peer address. Experimental results from the aforementioned testbed were reported, demonstrating the feasibility of our architecture.
