With the rapid development of mobile communication and the proliferation of mobile terminals, multimedia mobile business (MMB) is proposed and becomes a hot point of the research. 4G networks where the bandwidth wonpsilat be the transmission bottleneck will provide powerful support to MMB. As an important part of 4G, MANET is not capable of providing MMB because of the varying wireless channels, so...
We propose a concept for public safety communication realized with IMS (IP multimedia subsystem), the cellular standards of 3GPP and packet switched transmission. Basing the solution on mainstream cellular technology leverages the economy of scale of today's commercial networks and enables migration of technical solutions and applications. Important requirements of the public safety sector are group...
Dynamic spectrum management (DSM) is a key feature for enhancing cooperation in wireless video sensor network (WVSN) towards supporting communication of high data-rate video information. Unlike traditional spectrum allocation, DSM in WVSN should have topology control and distributed control center. In this paper, we propose an ILST algorithm for constructing distributed DSM topology control with the...
