An Effective Implementation of Multi-Path Routing Protocol in Wireless Mesh Networks

This paper’s contribution is a multi-path routing protocols that emphasize different aspects of multi-path routing. Multi-path protocols, which can provide larger bandwidth to the WMN. The network performance (end-to-end delay and packet loss ratio) compares favorably to the single-path DSR protocol, though as might be expected there is a trade-off against control packet overhead. In a WMN, the traffic load tends to be unevenly distributed over the network. We design a routing scheme which maximizes the utility, i.e., the degree of user satisfaction, by using the dual decomposition method. The goal of the metric is to choose a high-throughput path between a source and a destination. Our metric assigns weights to individual links based on the Expected Transmission Time (ETT) of a packet over the link. The proposed routing scheme in a fully distributed way. With the proposed scheme, a WMN[1] is divided into multiple clusters for load control. A cluster head estimates traffic load in its cluster. Based on the routing metrics, user traffic takes a detour to avoid overloaded areas, and as a result, the WMN achieves global load balancing.
