Abstract

Abstract:

Considering server problem for MM (Mobile Multimedia) systems, such as the bandwidthconstrained, the burden of server and proxy, which is affected by client persistent increasing. In order to improve the network transmission bandwidth of mobile multimedia, reduce the load of multimedia source server and proxy server, and improve the hit rate of multimedia requested data, reduce response time, this paper proposes CTMM (Clusterbased Threetier Middleware Model) architecture, based on traditional mobile multimedia twotier structure model. Firstly, it elects the local mobile nodes with excellent performance. Secondly, it organizes and manages these nodes to form clusters. Then it uses cluster supernode selection strategy to select appropriate local nodes to provide resource for servicerequestors. Simulation results demonstrate validity of CTMM.

Key words: mobile multimedia, resource discovery, supernode, cluster
