A Throughput Optimizing Routing Protocol for Wireless Mesh Networks

Wireless mesh networks (WMNs) have emerged as a key technology for next generation wireless networks showing rapid progress and inspiring numerous applications. The persistence driving force in the development of WMNs comes from their envisioned advantages including extended coverage, robustness, self-configuration, easy maintenance, and low cost. However, to support real-time applications, WMNs must be equipped with a robust, reliable and efficient routing protocol so that packets can be routed through them with minimum delay. In this paper, we identify some critical factors in designing a routing protocol for WMNs, and propose an efficient and reliable routing protocol. The protocol is based on a reliable estimation of wireless link quality and the available bandwidth on a routing path. It also minimizes control overhead by effectively controlling broadcast messages in the network. Simulations carried out on the protocol demonstrate that it is more efficient than some of the current routing protocols.
