A Multi-metric Routing Protocol to Improve the Achievable Performance of Mobile Ad Hoc Networks

Abstract

In recent years, with the rapid development of mobile technology, mobile ad hoc networks (MANETs) have been deployed in many areas such as rescue, military, medical applications and smart cities. Due to the characteristics of MANETs, routing protocols must be designed to be flexible, energy-efficient and highly performance achievable. In this study, we propose a multi-metric routing protocol with a cost function based on a set of three parameters: the length of the queue of packets at nodes, the link quality and the route hop count. Depending on the actual working condition of the network, one or more parameters may be involved in calculating the route cost. The simulation results show that our proposed routing protocol with the new cost function outperforms the conventional AODV protocol as it gains a better achievable performance.
