Abstract:

A cooperation diversity-aware routing metric for 802.11s-based wireless Mesh networks(WMNs) is proposed. Furthermore, a cooperation diversity-aware routing protocol (CDARP) and a cooperative MAC protocol (CMAC) are proposed, and both the protocals are adapted to the characteristic of WMNs. By building up virtual nodes and calculating the routing metric for virtual links, CDARP-CMAC can select the most reasonable path to cooperatively transmit packets. The simulation results show that, compared to the traditional cooperation scheme, CDARP-CMAC improves the good put by 5%~13% and reduces the drop rate by 5%~10%.

Key words: wireless Mesh networks, cooperative diversity, routing protocol
