Abstract

Routing in mobile ad hoc network (MANET) is challenging due to its mobility feature. The main reasons of link failures are mobility, interference and congestion. Mobility means, each node is free to move within its transmission range. Interference occurs due to collision and hidden nodes. Signal strength is considered as cross layer interaction parameter for implementing cross layer design (CLD). Received signal strength is taken from physical layer and is checked at MAC layer, whether it is above certain threshold. If it is above threshold then link is strong, otherwise it is a weak link, which can cause route failure; this condition is applied under mobility of nodes. When a route is likely to fail due to weak signal strength of a node, it will find an alternate path. Ad hoc on demand distance vector (AODV) has better performance in MANET. This review paper studies different issues of AODV protocols and CLD.
