Group-Server Scheduling for Continuous Multimedia Streaming in MANETs

At present mobile devices are prevalent with end users and continuous media streaming services in mobile ad-hoc networks (MANETs) support popular applications. One of the requirements for applications that stream isochronous media is that the network link has to be continuously available. In this study, we introduce two group-server scheduling schemes to improve link continuity: static group-server scheduling and dynamic group-server scheduling. With our solution, if one of the current links between a client and a server instance breaks, the client can still download the multimedia content from another scheduled server peer. The simulation results show that the proposed schemes significantly improve the effective link duration in MANETs.
