Mobile ad-hoc network is characterized by infrastructure less nature. It is a collection of wireless mobile nodes dynamically forming a temporary network. Each node in MANETs can act as a router or host on the network. The nodes are free to move randomly. Mobile Ad hoc NETworks (MANETs) are characterized by rapid change, dynamic multi-hop topology. The main types of routing strategies are proactive, reactive and hybrid. Traditionally, routing protocols for ad-hoc wireless networks provide a non-adversarial environment and an environment of cooperative network.
