MANET stands for Mobile Ad hoc Network. Mobile ad hoc network is an arrangement of wireless nodes which are free to move and are not controlled by any centralized mechanism. Nodes in mobile ad hoc network act both as hosts as well as routers. The nodes establish a dynamic network. Due to this dynamic nature of topology, Link Failure problem often degrades the network performance. This paper outlines link failure problem in Mobile Ad hoc Network. A new method has been proposed to eliminate link failure in Mobile ad hoc network by using signal strength parameter in AODV and provide a stable path for data transmission.

Keywords: MANET, link failure, AODV, signal strength.
