Abstract

For routing in multi-hop Wireless networks, the minimum hop-count metric focuses on finding the shortest path between nodes taking into account the mobility of the nodes as an important factor for identifying the best routes. However, in Wireless mesh networks (WMNs) due to the static nature of the nodes, minimum hop-count is not always the best criteria for routing; the shortest path might be slow or lossy leading to poor network throughput. In this research work, we use the Signal-to-Noise Ratio (SNR) metric as link-quality metric for finding high-throughput routes in WMNs. We modify the Dynamic Source Routing (DSR) protocol to choose routes according to the SNR metric. We apply the SNR as routing metric in the DSR module offered by OPNET simulator. The simulation results show that, the modified SNRDSR protocol has higher throughput than the original DSR protocol throughout all simulation scenarios.
