Abstract

Mobile AD hoc Networks as a special type of wireless networks have received special attention due to having some special features such as no need for central management, no need for infrastructure and high mobility capability. They can be used in cases where creating an effective communication infrastructure is neither cost-effective nor practically feasible, such as conferences, battles and post-disaster                   communications. Several routing protocols are proposed for these networks. ODMRP protocol is one of the most famous and widely used protocols in Mobile AD hoc networks. This study was carried out to discuss this routing protocol and aimed to provide a new routing method for increasing this protocol’s efficiency. In the ODMRP protocol, the optimal route is selected based on the shortest route. In wireless communications with the nodes getting away from each other, the received signal levels are weakened and may result in loss of data, and in practice, the shortest path that works based on a smaller number of hops loses its effectiveness. In the proposed protocol, the route is selected based on the received signal strength level.  According to the simulation results, control overhead decreases by %30 and packet delivery rate increases by %10, demonstrating performance improvement of the devised protocol compared to the original one.
