Mobile Ad hoc NETworks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among them without the need of fixed infrastructure. Due to limited transmission range of wireless network nodes, multiple hops are usually needed for a node to exchange information with any other node in the network. Thus, routing is a crucial issue in the design of MANET. On-demand routing protocols for mobile ad hoc networks discover and maintain only the needed routes to reduce routing overheads.
