Mobile Ad-hoc NETwork (MANET) is a peer-to-peer wireless network. They are self-configuring, capable of self-directed operation and hastily deployable. In MANET nodes communicate with each other without the use of topology. Nodes are itinerant, topology can be very dynamic and nodes must be able to relay traffic because corresponding nodes might be out of range. The dynamic nature of MANET makes network open to attacks and unreliability. Routing is always the most noteworthy element for any networks. Node misbehavior due to selfish or malicious intention could significantly degrade the performance of MANET.
