Link Quality Based Multipath Routing Protocol in Wireless Mesh Networks

In Wireless Mesh Networks (WMNs), the source relies on intermediate nodes to reach the destination. As a result, failure in a node greatly affects the transmission of data. To overcome this drawback, multiple paths are required to favor the data transmission without any obstruction. In this paper, the authors propose a link quality based multipath routing protocol in wireless mesh networks. In this protocol, the source discovers multiple paths to the destination using parallel layer based approach. This approach organizes the nodes into multiple layers and discovers multiple paths using breadth first search algorithm. From multiple paths, the primary path is elected using Expected Forwarding Counter (EFW) metric. They evaluate their approach using Network Simulator 2 (NS-2).
