Abstract: This paper presents a load-balancing routing (LBR) algorithm for multi-channel wireless mesh networks (WMNs). The objective of this algorithm is to reduce interference and balance network load among links. The LBR algorithm is composed of link allocation algorithm and load-balancing route-selection algorithm. First, the network model is presented. Based on this model, a link allocation algorithm is proposed to allocate all links to channels which aims to minimise interference degree of networks. After links are allocated to channels, a route-selection algorithm is proposed to select a path from source to destination to balance network load. Simulation results demonstrate that the proposed algorithm balances network load and improves the network throughput significantly.

Keywords: multi-channel WMNs; load balancing; routing protocols; link allocation; wireless mesh networks; route selection; simulation; network throughput.
