A New Proactive Routing Protocol for MANET

In this paper, we introduce a new proactive routing protocol (NPRP) in which a link breakage prediction algorithm is used for the routes selection. The link breakage prediction algorithm is based on the signal power strength. Each mobile node uses signal power strength from the received packets to predict the link breakage time, and sends a warning to the source node of the packet if the link is soon-to-be-broken. If source receive this message it starts using backup route and if back route also fails then it finds alternative route. The backup route will minimize the time consuming process of finding an alternative route to some extent. Experiments demonstrate that adding link breakage prediction to DSR can significantly reduce the total number of dropped data packets by at least 25%. Simulation results show the probability of the communication breakage decreases when parallel routes are used and comparisons between DSR and Modified DSR with respective to no of broken paths and routing overhead.
