We proposeanEnergy Aware Multipath AODV protocol (EAMAODV) based on AODV. EAMAODV obtains nodes energy by upgrading the route discovery and route maintenance process of AODV. It calculates drop rate derived by routes total hops. Drop threshold is used in deciding the route. Simulation is done using NS-2.35. The results show that EAMAODV has higher packet delivery ratio and throughput than classical AODV protocol. Keywords—AODV, nodes energy, Multi-path routing, residual Energy I. Introduction MANET is a self-creation, self-organized, self- managed,infrastructureless wireless network [1]. it is widely used in defence and civil fields because of its characteristics of mobile communication. It has a dynamic topology and limited energy, which makes its routing protocol more complex than the traditional network [2-3]. Therefore, MANET network routing strategy focuses on how to balance the energy consumption of nodes, increase the network lifetime, establish a backup routing and shorten the network delay. A high energy nodes driven strategy for routing discovery has been proposed, through high energy node to transmit data to balance the network energy consumption [4]. A routing protocol to avoid low energy nodes, to increase nodes lifetime by setting the node energy threshold, reducing the low energy nodes over involved in data forwarding [5]. A forward a fast link algorithm for fault routing link on the thoughts of fast repairing was introduced [6]. The above documents made corresponding improvement and optimization on the energy and route repair of the route discovery process, because of without considering the multi- routing, the route discovery process still need to be carry on to repair the broken link, it will prolong the delay. Based on document [5], this paper improved a multi-path routing improved protocol in AODV based on nodes energy, establish multiple paths from the source node to the destination node by setting node energy threshold, When communication breaks, using alternate routing in a timely manner, so as to shorten the network delay. If there is breakage somewhere, the backup routing will be used timely to reduce the network delay [7]- [10].The rest of the paper is organized as follows. We begin with Section II of discussing related work. In Section III design and implementation is described. Section IV describes simulationand result Section V conclusion. II. Related Work The proposed work is aimed at developing an energy efficient AODV routing protocol therefore this section studies some of the many energy efficient schemes using AODV algorithm developed by researchers in the field. In [6], Jin-Man Kim and Jong-Wook Jang proposes an enhanced AODV (Ad-hoc On- demand Distance Vector) routing protocol which is modified to improve the networks lifetime in MANET (Mobile Ad-hoc Network). One improvement for the AODV protocol is to maximize the networks lifetime by applying an Energy Mean Value algorithm which considerate node energy-aware. Increase in the number of applications which use Ad hoc network has led to an increase in the development of algorithms which consider energy efficiency as the cost metric. In [11], Yumei Liu, LiliGuo, Huizhu Ma and Tao Jiang propose a multipath routing protocol for mobile ad hoc networks is proposed, called MMRE-AOMDV, which extends the Ad Hoc On-demand Multipath Distance Vector (AOMDV) routing protocol. The key idea of the protocol is to find the minimal nodal residual energy of each route in the process of selecting path and sort multi-route by descending nodal residual energy. Once a new route with greater nodal residual energy is emerging, it is reselected to forward rest data packets. It can balance individual node’s battery power utilization and hence prolong the entire network’s lifetime. In [12], Zhang Zhaoxiao, Pei Tingrui and ZengWenli propose a new mechanism of energy-aware named EAODV for Ad Hoc is proposed in this paper, which is based on the classical AODV (the routing protocol on demand). And backup routing mechanism is adopted. In EAODV, the route which spends less energy and owns larger capacity is selected by synthetic
