Performance analysis of broadcasting in small-scale Multi-Radio Multi-Channel Wireless Mesh Networks

Multi Radio Multi Channel Wireless Mesh Networks (MRMC-WMNs) are undergoing rapid progress and inspiring numerous deployments. These networks require carefully assignment of resources and load balancing to provide the quality guarantees to traffic flows. Load balancing avoids the creation of bottlenecks and increases the network efficiency. Certainly, we need a benchmark to compare the performance of different load balancing mechanisms. In this paper, we consider the scenario of bandwidth-guaranteed broadcast sessions, where each session has a specific bandwidth requirement. The aim of this research is to analyze the performance of broadcasting in small-scale MRMC-WMNs. By considering Wireless Broadcast Advantage (WBA), we formulate channel and node constraints and propose “Traffic Engineering Efficiency” to evaluate the load balancing ability of algorithms. Deriving analytical relationships between throughput, number of transmissions, node and channel utilization is other contribution of this paper. In order to confirm the accuracy of derived analysis, we present some simulations on typical networks.
