MANET is a self-organized, decentralized wireless network with mobility as core functionality. Routing is key in to enhance MANET performance. Routing in mobile ad hoc networks and some fixed wireless networks use multiple-hop routing. Routing protocols for this kind of wireless network should be able to maintain paths to other nodes and in most cases, must handle changes in paths due to mobility. AODV is most popular routing protocol among others. It is on-demand type routing protocol and its performance is better than other routing protocols in MANET environment. This paper focus on AODV routing protocol to enhanced the break avoidance mechanism using multipath extension in core AODV to avoid route break problem in existing AODV method.
