3MOKAN: A Novel Mobility Management Mechanism Based on Keeping Alternative Nodes

A mobile ad hoc network (MANET) is a network without any predefined infrastructure in which every node not only enjoys the services from the network, but serves the network as a relaying router. Because of nodes mobility, these kinds of networks are highly dynamic. Therefore, link failure is so frequent. In this paper we propose a novel mobility management method which is independent of underlying routing protocol. Based on this mechanism, a node tries to keep an alternate node for its next hop and when a link breakage occurs, simply node uses its alternate node as next hop. Simulation results show that this mechanism can reduce average number of hop counts, number of selected routes and number of broken links, and provide longer network lifetime.
