Behavioral study of Random Waypoint Mobility Model based energy aware MANET

Mobility pattern of an adhoc network affects its connectivity. Random Waypoint Mobility Model is widely followed by Mobile Adhoc Networks (MANET) in real world scenario. This mobility model is popular because it represents random motion of nodes which can move in any direction at any moment at a random speed. In this paper, the connectivity of a MANET, following Random Waypoint Mobility Model has been studied. Its formula contains two parameters among which, the first one is the number of nodes that are within the transmission range of each other. Residual energy of the nodes is the other parameter that has been introduced in establishment of connectivity between nodes. Energy consumption of a node depends on the number of applications running in it. Here, the energy consumption index is proportional to the number of applications running. The number of applications running in a node is a random function which attributes to energy consumption. Also, there are two cases among which, the first one considers all the nodes are fully charged initially. In second case, initial energy of each node is a random function which also attributes to energy consumption. For both the cases, we have studied node connectivity by changing different parameters like number of user nodes, simulation time and simulation area dimensions. This study of connectivity was never done before and hence the need was felt.
