A Novel WiMAX Structure with Mesh Network

IEEE802.16 (WiMAX) is a wireless metropolitan area network standard with high transmission speed and great coverage. Point to multi-point (PMP) is the traditional WiMAX transmission mode. Wireless mesh network (WMN) is an attractive and useful structure which is suggested to be adopted in WiMAX. A smart WiMAX structure with mesh is proposed in our paper, which supports direct data transmission between SSs (subscribe stations) with the control of the BS if possible. This mesh model is easy to achieve, and could improve the system performance such as throughput and propagation delay. With the help of the BS, several key problems in pure wireless mesh network are satisfactorily solved, such as coexistence, interference and billing. Simulation results are presented in this article to show the enhancement gain of the system performance by the smart model. The idea of virtual cell is put forward to benefit analysis, and the performance with AMC scheme is considered too. More concrete descriptions and explanations are given in the article.
