Performance evaluaron of energy efficient for MANET using AODV routing protocol

In recent times, mobile ad-hoc network (MANET) has become a growing interesting field for researchers. Mobile ad-hoc network is an ensemble of mobile nodes which is gently connected without any centralized base station of network. For transmitting data from one node to another node routing protocols are used. This paper focus on AODV routing protocol that is one of extensively used routing protocol in MANET. Energy consumption is a main issue in Ad hoc network which speciously builds attention today. AODV routing protocol is not consider energy of nodes in route discovery phase. If less energy of node occurs in between the path, it causes packet dropping. It leads to link-failure problem. After that system reinitiate RREQ message from source node again. Therefore, it causes more energy consumption. To overcome this issue, we proposed a new technique based on existing AODV routing protocol without disconnection of route after link failure problem. This scheme does not cause link failure problem and avoid rebroadcast message again from source node. This gives a significant improvement in node energy. The simulation result shows that proposed technique will enhance the energy of network. The comparison results between proposed AODV and existing AODV routing protocols are shown in terms of various QoS parameters such as throughput, energy spent, end to end delay and packet delivery ratio. This simulation work is analyzed using NS-2 simulation tool (NS-2.35) under Ubuntu 14.04 LTS as operating system.
