Mobile Ad-hoc Network (MANET) is a Network, which permits the mobile nodes to commune in lack of a permanent Infrastructure. Nodes in MANET communicate via wireless multi hop links. MANET provides a good platform for any time anywhere networking. Due to frequent node movement routing algorithm in wired network is not suitable for MANET. Several separate routing algorithms have been designed for MANET. Among this, AODV is the most popular routing algorithm. AODV is the on demand routing algorithm and two phases of this are route establishment and route maintenance. Route maintenance is the major issue in AODV when there is only one path is established between source and destination. Wireless link breakage is higher in ad-hoc networks due to the node movement, so alternative paths are needed for the route maintenance. This paper explores the need for saving the alternate path for path maintenance and also gives a new idea for finding an alternative path in AODV during link failure.
