Abstract :
Mobile Ad hoc Networks (MANETs) is about mobile nodes roaming around the network area. Simulation is one of the methods for evaluating the characteristics of Ad Hoc networking protocols. Mobility model of the network simulator is very important. The mobility of the nodes directly impacts the performance of the protocols. The simulation results obtained with unrealistic movement models may not correctly reflect the true performance of the protocols. The majority of existing mobility models for ad hoc networks do not provide realistic movement scenarios; they are limited to random walk models without any obstacles hence the need to address mobility with obstacles. In this paper, we proposed a solution to realize a realistic movement models through the incorporation of obstacles by studying the Performance Evaluation of campus mobility model in Mobile Ad Hoc Networks. Therefore, the objective of our proposed Campus Mobility Model (CMM) has been designed to model the movement of mobile nodes in terrains that resemble the real world topographies. The objects model buildings and other structures that provide a barrier to both the movement of the mobile nodes, as well as the wireless transmission of these nodes. In modeling such a terrain, a user can define the positions, shapes and sizes of these objects. Finally we evaluated the Campus Mobility model based on physical characteristics and the impact on network topology and routing performance. Simulation results showed that the use of obstacles and pathways has a significant impact on the network topology and the performance of the routing protocol.
