Adaptive Route Selection in mobile ad hoc networks

This paper presents an adaptive routing protocol named Adaptive Route Selection in Mobile Ad Hoc Networks (ARSMA). The aim of this work is to improve the delivery ratio and reduce the end-to-end delay. In the route request phase, source nodes will discovery multiple routes to the destination node, one for primary path, and the others for the backup paths. During the discovery procedure, each node will estimate the link expire time by way of the moving speed and direction of the precursor node. When a link breakage is about to occur, source node will try to switch the transmission to the backup route. The simulation result shows that ARSMA is able to improve the delivery ratio and reduce the end-to-end delay.
