An asymmetric routing protocol using detour in mobile ad hoc networks

Abstract

In mobile ad hoc networks, reliability and connectivity between all nodes is maintained by routing protocols. Most on-demand routing protocols in mobile ad hoc networks support only symmetric links that can receive messages from neighboring node on each other. Unfortunately, this assumption of the existing protocols is inconsistent with reality. In fact, the asymmetric links are considered as broken or failed links by the existing routing protocols, so connectivity between nodes cannot be maintained and finally this cause performance degradation. In this paper, we propose an asymmetric routing protocol using a detour to cope with this problem in mobile ad hoc networks. Experiments with the Global Mobile Simulation tool shows that our protocol can improve routing performance by providing better connectivity and throughput of the network.
