A stable weight-based routing algorithm to increase throughput in Mobile Ad Hoc Networks

A Mobile Ad Hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. In MANET, the high mobility of mobile nodes is a major reason for link failures. In This paper we propose a novel weight-based approach for routing algorithm in mobile ad hoc networks, called weight-based AODV (WBAODV). The proposed scheme uses the weight-based route strategy to select a stable route in order to enhance system performance. The weight of a route is decided by four factors: the speed of nodes, the power level of battery, the Bandwidth, and the hop count. Our study also compares the performance of the WBAODV protocol with the well-known Ad hoc On-Demand Distance Vector (AODV) protocol. Results obtained by a simulation campaign show that WBAODV allows obtaining some important advantages that makes it a valuable candidate to operate expenses of the optimality of the solution, it results to be particularly suitable in environments where fast communication establishment and minimum signalling overhead are requested. Also simulation results show the improvement of the network performance, in terms of throughput, delay, and hop count, through use of the routing algorithm.
