Cluster heads (CHs) form the backbone of the crucial inter-cluster communication for wireless sensor network (WSN). Due to relaying high data traffic, some of these nodes quickly exhaust their precious energy and increase the risk of node failure. In conjunction with the node failure, data packet loss also occurs in a CH due to congestion and poor link quality. Traditional routing algorithms choose...
One crucial issue for routing in wireless ad hoc networks is how to select a reliable path which depends on the availability of the links constituting the path. So a good estimation of link reliability between neighboring nodes could permit the selection of a more reliable route. Due to the nature of the wireless ad hoc networks, mobility and radio propagation etc., it is not easy to collect enough...
