Enhancing Multi-Hop Wireless Mesh Networks With a Ring Overlay

Wireless Mesh Network (WMN) has become popular access network architecture. But because of its multi-hop nature, co-channel interference and contention, the attainable capacity of a wireless node in a WMN is significantly less than the radio capacity. The authors propose a overlay architecture for a WMN, where a wireless-ring (WRing) is deployed over the regular mesh for carrying wireless mesh traffic only. The analysis shows that WRing improves the performance of a WMN significantly by reducing the interference and contention.
