A Novel Multicast Beneficiary in IEEE 802.16j WIMAX Relay Networks

In IEEE 802.16j based Wimax multihop-relay network, in addition to a base station, multiple relay stations are used for enhancing the throughput, and improving the coverage distance of the base station. Multicasting is a more efficient method of sup-porting group communication than unicasting, as it allows transmission and routing of packets to multiple destinations using fewer network resources. An important issue in the multicasting of Wimax multihop-relay networks is the improving multicast recipients and most existing algorithms try to minimize the total energy of a multicast tree. In contrast to this problem the authors propose Optimum Subscribe Station Serving (OSSS) scheme to improve multicast resource utilization by improving number of recipients in multicast tree for given resource budget.
