Simulative study of random waypoint mobility model for mobile ad hoc networks

Connectivity of Mobile Ad-hoc Networks (MANET) is highly dependent on the mobility model it follows. From previous studies, it has been found that Random Waypoint Mobility Model (RWP) is widely used to simulate performance of the MANETs. This mobility model resembles the mobility of people using mobile phones in a given area. Connectivity is an important issue in a MANET following RWP model and hence researchers are trying out different ways to enhance connectivity. So, this model is considered and the variation of connectivity for different varying parameters is studied. The RWP model is simulated in MATLAB, followed by the study of the node connectivity by changing different parameters like number of user nodes, simulation time and simulation area. Further, it is shown that connectivity is enhanced in each case after introducing agent nodes. This study gives an estimate of number of nodes required for achieving desired connectivity of the network.
