Research And Implementation Of Mobility Control Algorithms In Wireless Ad Hoc Networks

Nowadays, wireless ad hoc networks has been one hot research subject in telecommunications technology fields because of it's wirelessness, self-organizing and multihop characteristic. How to maintain the Ad Hoc network connectivity is one of the basic problem.Since every node in a multihop (or ad hoc) network is responsible for forwarding packets to other nodes, the failure of a critical node can result in a network partition and communication interrupt. In the paper, we develop a distributed self-repairing mobility control algorithms that move correlative nodes to repair the network connectivity if a critical node was failure, and then efficiently prolong the network's lifetime.The rest of this paper, we establish a OPNET simulation model and simulate the distributed self-repairing mobility control algorithms via this model. In the end, we analyze the simulation result.
