A route control method based on cross layer approach between Physical and Media Access Control layer

In this paper, a route control method for ad-hoc networks in a multipath fading environment is studied which is based on received power of repeater nodes and the history of established links. When repeater nodes received HELLO Message, these nodes obtain the received power information from Physical Layer in order to decide whether a link is stable or not. If the received power is lower than a threshold, repeater nodes start route discovery procedure while maintaining the link by referring the history of established link. From the results of computer simulations, it has been clarified that the route discovery time of the proposed method is shortened by about up to 1.8 s, the route effective time is lengthened by about up to 13 s and the average throughput is improved by about up to 50 kbps from the previous proposed method which is an improved method of AODV.
