Performance Evaluation of Wireless Networks With Power Saving Support

Ad hoc networks, a subset of wireless networks, allow the formation of a wireless network without the need for access point. All participating users in an ad hoc network agree to accept and forward messages, to and from each other. Mobility management with reference to handoff management has widely been recognized as one of the most important and challenging issue in ad hoc network. Mobility of node is defined by various mobility models. Evaluating mobility models within an ad hoc network gives solution to find out performance measures like blocking probability, handoff probability, dropping probability, hop count, delay etc. This research is an investigation in search of the effect of Random Walk, Random Waypoint and Gauss Markov mobility models on performance of mobile ad hoc network. Power of nodes in ad hoc networks is supplied with batteries hence power-saving is an important issue. This paper also focuses on energy calculations.
