Abstract

Most routing protocols in Mobile Ad hoc Networks (MANET) select route based on the shortest path metric. In dynamic topology networks, such as MANET, nodes are prone to being unreliable due to the intrinsic characteristics of MANET like interference, mobility and congestion. Shortest path metric in MANET may lead to selection of unreliable nodes which in turn degrade the overall performance of MANET. Thus, there is a need of routing metric which attune with these characteristics and select reliable path instead of shortest path. In this paper, we utilize the cross-layer parameters to predict the node mobility, channel interference and link congestion factors and assign a link cost to the node. We propose Reliable Route Metric to select reliable route from the available number of paths using Cross-layer Link Cost. Our simulation results show that the proposed metric reduces packet losses and increases the network throughput.
