Study on the Routing Metric of Multi-channel Wireless Mesh Network

Basic on the routing metric WCETT of Wireless Mesh Network, a new routing metric named WCETT-WR is proposed in this paper. It contains parameters about backoff time to wait for the channel and interference within and between paths. In order to strike a balance between various factors, two weighting parameters named and are also introduced into WCETT-WR. It can be known from the simulation results that the WCETT-WR metric can significantly improve the network performance.
