Abstract

It is a well-known fact that routing metrics play a crucial part in the performance of wireless mesh networks (WMN). When routing protocols are implemented, the routing metrics are assigned to different paths. It calculates the best path to predict the best routing path. They are integrated in routing protocols to improve WMNs efficiency in terms of reliability, latency, throughput, error rate and cost. This paper addresses inter-flow interference, intra-flow interference and load balancing problem in multi hop WMNs. We have presented a new load balancing interference aware routing metric (LBIARM) that captures intra-flow interference, inter-flow interference and traffic load. The performance of LBIARM was then evaluated by comparing it with weighted cumulative expected transmission time metric (WCETT) using grid topology. OPNET Modeler 16.1 PL1 was used as a simulation tool for implementation.
