Performance comparison of modified AODV in reference point group mobility and random waypoint mobility models

A Mobile Adhoc Network (MANET) is characterized by high mobility, non-infrastructure network, and dynamic topology. This nature make MANET have some constraints such as energy constraints, limited bandwidth, and less memory. Energy consumption becomes an important issue in manet to cover the sustainability of the communication process. We have proposed optimize routing protocol based on AODV routing protocol for hybrid network. We used reverse mechanism to optimize the AODV routing protocol. In this paper, we will analyze the performance of our proposed protocol in term of energy consumption, packet delivery ratio, end to end delay and routing overhead. We evaluate our proposed protocol with NS-2, with some scenario using random waypoint and reference point group mobility model. In the Random Waypoint model (RWP), each node chooses a new destination randomly and then moves towards the destination at a constant speed. In RPGM, it will create some group of nodes. Each group has a logical center that defines the entire groups motion behavior, including location, speed, direction, and acceleration. The simulation result shows that our modified protocol is outperform in random waypoint rather than in rpgm. In term of energy consumption, our protocol achieved lower consumption for random waypoint mobility compare to the reference point group mobility model.
