Abstract: Mobile ad hoc consists of mobile nodes that can move from one location to another location freely at any time to any directions. Mobile nodes are linked together to transfer data packet from source node to destination node. Two nodes can communicate to each other using the link between them. If the link between the two nodes is broken, the two nodes cannot communicate to each other. In MANET, two nodes can communicate directly if only if they are in the same range. In different range they use intermediate node to forward information. To transfer data packet from source to destination it needs enough energy and received power. Nodes are linked together to facilitate the routing protocol in MANETs. When nodes have no enough energy and received power the link between each node is not working properly to transfer the required information and it decreases the quality of services in the network. This problem makes the performance of whole network low. When the performance of network became low it reduces throughput, packet delivery ratio, increase packet loss and overhead etc. Some routing protocol selects shortest path but selecting only the shortest path is not enough to send data packet. Based on the above problem this thesis proposed to improve the performance of AODV routing protocol by computing the received signal strength and residual energy of nodes for mobile ad hoc network. In this work, network simulator 2 (NS2) is used for simulation purpose. The simulation results demonstrated in terms of packet delivery ratio, throughput, residual energy, consumed energy and end-to-end delay. The simulation result shows that the amount of energy consumed was reduced and but the amount of residual energy in the new solution increased in all scenarios, packet delivery ratio increased as number of nodes increased, end-to-end delay decreased and the average throughput increased in new solution when compared with the existing AODV routing protocol as shown under Table 3, 4,5,6,7.
