A Routing Metric for Load-Balancing in Wireless Mesh Networks

Abstract

This paper proposes a routing metric known as weighted cumulative expected transmission time with load balancing (WCETT-LB) for wireless mesh net works. WCETTT-LB enhances the basic Weighted Cumulative Expected Transmission Time (WCETT) by incorporating load balancing into the routing metric. Unlike other existing schemes proposed for load balancing for wireless mesh networks, WCETT-LB implements load balancing at mesh routers. WCETT-LB provides a congestion aware routing and traffic splitting mechanism to achieve global load balancing in the network. The preliminary qualitative and quantitative analyses show the significance of the proposed scheme.
