SNR-based Dynamic Sequence Distance Vector routing protocol metric for mobile ad-hoc networks

Mobile ad hoc networks (MANETs) are consists of mobile devices connected wirelessly. Mobile nodes in MANET are applicable of routing functionality, where messages are forwarded in a multi-hop fashion. In such a communication scheme a routing protocol play an important role in the network performances. The wireless connectivity and node mobility in MANET networks contributes in rapid topological changes, which brings the need for a channel aware routing protocol. To overcome this problem, many channel aware routing metrics are proposed in the literature, however these routing metrics are either utilizing the shared bandwidth to measure the link quality, or they implies less awareness to the link quality. This paper proposed a SNR-based routing metric for Dynamic Sequence Distance Vector (DSDV) routing protocol. This paper starts by investigate and compare the performance among common routing protocols in MANET. Secondly a cross layer approach is proposed for the new routing metric. Simulation scenarios are used for the work of the paper. The new metrics is implemented in one of the MANET common routing protocols DSDV module in MONET++. The results show that SNR-based DSVD improves the performance of the MANET in terms of throughput and delay.
