Impact of Mobility-Adaptive Mechanisms on Stability-Orient Routing in Mobile Ad Hoc Networks

Although establishing stable routes for routing can improve the performance of mobile an hoc networks (MANETs), the improvement will be weakened to a degree for the stability of route is sensitive to the motion of node. In this paper, based on a basic stability-oriented routing scheme, named FORP, we involved two mobility-adaptive mechanisms in it. One mechanism is the real-time update of stability with the motion of node. The other one is the pre-discovery of the backup route and we gave the rule to regulate this process. The aims of the mechanisms are to make the stability of route be adaptive to the mobility and weaken the bad impact of motion on performance of MANETs further. Then NS-2.29 is used as the simulation tool to study the impact of the mechanisms on FORP. The results show the two mechanisms can further improve the performance of MANET effectively.
