A Mobile Ad-hoc NETwork (MANET) is a self-configuring network composed of mobile nodes without any fixed infrastructure. In a MANETs, there are no difference between a host node and a router so that all nodes can be source as well as forwarders of traffic. Moreover, all MANET components can be mobile. They provide robust communication in a variety of hostile environment, such as communication for the military or in disaster recovery situation when all infrastructures are down. A very important and necessary issue for mobile ad hoc networks is to finding the root between source and destination that is a major technical challenge due to the dynamic topology of the network.
