Impact of mesh backbone scheme on capacity of hybrid Wireless Mesh Networks

Wireless Mesh Networks (WMNs) are a promising technology for next generation wireless networking. Hybrid WMNs, the combination of backbone and client WMNs, are considered as the most applicable case. In this paper, the impact of mesh backbone scheme on the capacity of hybrid WMNs is analyzed in terms of both the per router throughput capacity and the per client throughput capacity. Furthermore, the performances of hybrid WMNs adopting different backbone schemes are compared. NS2-based simulation results are presented to show the throughput capacity of hybrid WMNs with different mesh backbone schemes.
