Optimizing IEEE 802.16j: Multihop Relaying in WiMAX Networks
For the global deployment of mobile WiMAX networks the limited budget of installation and efficiency of network quality are very important concerns. To optimize the WiMAX network quality of services in term of good data rate guarantee and the efficient radio spectrum to serve as more as possible users more and more coverage should be provided. For enhancing the radio coverage of the WiMAX network multi-hop relay station technique is proposed. IEEE 802.16 forum gives different types of service flows (i.e. UGS, RTPS, ERTPS, NRTPS and BE) for various kinds of applications.
