A MANET Routing Algorithm Based on Difference Degree and Stability of Nodes

Aiming at the team-based mobile ad-hoc networks (MANETs), this paper proposes a main-route mechanism by the mobility difference degree of nodes and a backup route mechanism by the nodes stability. In this paper, the whole network is divided into different partitions, and the prediction node computes the changing rate of local topology to determine whether local status broadcast is needed. In order to reduce the similarity of the main route and backup route and minimize the probability of simultaneous failure of the two routes, different routing metrics are used to discover these two routes to ensure reliable data transmission. As a result, the availability of backup route can be increased when the main route fails. While a link is broken, we advance a novel local confirmation method of link interruption and local route reparation. The simulation results shows that our routing algorithm is effective and can improve the network performance significantly. Copyright © 2013 IFSA.
