Abstract: Ad- hoc network is the network comprised of centralized base network and a mobilized network which communicate with each other. While communicating with each other, sensor nodes determine the shortest path to the destination nodes. As the sensor node operates over the limited battery power, it is very important to determine the efficient algorithm and routing protocols to fulfill the energy requirements of the network. To make the network secure, faster and energy efficient, we have to make changes in the routing protocols at the various (MAC and PHY) layer of the networks. In this paper, we carried out these changes to the LANMAR, DSR AND ZRP protocols and studied the effects in term of Throughput, end to end delay and Jitter at the application layer. The simulation results are carried out in QualNet 6.1 Simulator.
