Performance Evaluation of Wireless Mesh Networks with Self-Similar Traffic

In this paper we evaluate the performance impact of traffic patterns on wireless mesh networks. Modeling and simulation of the wireless mesh networks were performed using the NS-2 tool. Trace-driven simulations with genuine traffic trace collected from the wireless mesh networks are used to evaluate the performance. This trace tends to exhibit long-range dependent behavior. Simulation results indicate that genuine traffic traces, compared to traditional traffic models such as the Poisson model, produce longer queues and, thus, require larger buffers in the deployed networks' elements.
