Energy-efficient position based routing protocol for mobile ad hoc networks

A MANET is a collection of mobile nodes communicating and cooperating with each other to route a packet from the source to their destinations. A MANET is proposed to support dynamic routing strategies in absence of wired infrastructure and centralized administration. In such networks, limited power in mobile nodes is a big challenge. So energy efficient techniques should be implemented with existing routing protocols to reduce link failure and improve the network lifetime. This paper is presenting an Energy-Efficient Routing protocol that will improve the utilization of link by balancing the energy consumption between utilized and underutilized nodes to meet the above challenge. The protocol deals with various parameters as Residual Energy, Bandwidth, Load and Hop Count for route discovery. The failure of any node in the route when the transmission of data packet is in progress leads to the degradation of the QoS (Quality of Service). To overcome with this issue, the paper proposes two methods for maintenance of the route. The simulation results show that the proposed protocol achieves objectives like minimizing overheads, fast convergence speed, high reliability and gives enhanced results than previous techniques like DSR.
