الملخص

Applications of cooperative multicast communication techniques for emerging broadband multimedia services, such as Internet Protocol TV (IPTV), over WiMAX air interface have an important and attractive feature of reducing the network resource consumption, by broadcasting the data once to multiple users (e.g., TV channel group members) simultaneously indepdtly of their number, using a common shed downlink channel. But users distributed ound the cell face differt channel conditions due to fading, user location, mobility, and other related chacteristics. Several schemes were reported in the literature that attempt to introduce cooperative multicasting reliably and efficitly, some of which utilize subscribers with good-channel as relay agts (RA) to provide coverage for subscribers with bad-channel but fail to consider the huge amount of ergy consumed in the process. In this thesis, we propose ergy-efficit cooperative multicasting schemes by properly selecting RAs based on their location, channel condition and coverage. By exploiting the channel state information (CSI) and the location based service (LBS) techniques, protocol based on neest neighbor, transmission distance and subscriber-subscriber interlink instantaneous CSI were proposed and implemted in order to achieve much improvemt in the system performance. The number of RAs was vied in accordance to channel conditions and treated on a frame-per-frame basis. This approach considerably reduces the amount of ergy consumed as prov by analysis and simulation models, providing a lower cost coverage solution with no dereliction in achieving high throughput for all group members.
