A noval hybrid wireless routing protocol for WMNs

Wireless Mesh Network (WMN) is a new kind of broadband Wireless Network, mainly used for different application scenarios of wireless access. Hybrid Wireless Mesh Protocol (HWMP) is a default routing protocol provided for WMN by IEEE 802.11s. However, problems exist in this routing protocol, such as large overhead, low efficiency and so on. This paper propose a new routing mechanism, Source Node Compute Routing (SNCR) protocol for solving above problems, for the source node to quickly calculate the best-metric route to any destination of intra-mesh. The proposed protocol also combines proactive mode with on-demand mode to adapt to all traffic scenarios. The simulation results reveal that the SNCR protocol gets better improvement on performance such as packet delivery ratio, average end-to-end delay and routing overhead.
