Abstract :
A multi-hop wireless metropolitan area network (WMAN) is a metropolitan area network that adopts the wireless multi-hop technique to provide high-speed data link between adjacent nodes for metropolitan area. This work presents an improved wireless token ring (IWTRP) protocol for W-MAN. IWTRP adopts the concept of spatial reuse to enhance the throughput of the W-MAN via using multiple tokens. It provides mechanisms to enable multi-token circulation within a ring and to prevent from the possible packet collisions. An analytical model is further proposed to derive the per-node saturation throughput of the W-MAN. Simulation results demonstrate the accuracy of the analysis and the superiority of IWTRP
