Efficient Mobile node Hand-Over Mechanism using AOL by setting RWPB

Mobile nodes are not static. They will move on random possibilities within and beyond boundaries. Identifying node's random movement for data transmission is addressed in this paper. The common problem identified in Random waypoint movement is the lack in velocity distribution and solution addressed to this problem is Random Waypoint on the Border (RWPB). It has been addressed earlier and the solutions for this problem were velocity distribution. Generally poor velocity distribution will stop mobile nodes and make them stationary. Such nodes will remain idle over a period of time depending on velocity distribution. This scenario will effect node movement particularly in the aspect of mobile node handover management. We have proven this result in MANET for avoiding delay in mobile handover management by keeping every mobile node active. Mobile handover mechanism is the way for changing mobile control from one node to another without any latency. If latency prevails it leads to packet loss and delay distortion. Hence RWPB along with efficient Handover mechanism makes the MANET efficient in terms of its service and accessibility. The simulated results of this work were done with NS2 mobility pack.
