Ad-hoc networks are decentralized, self-organizing networks capable of forming a communication network without relying on any fixed infrastructure. Each node in an ad-hoc network is equipped with a radio transmitter and receiver which allows it to communicate with other nodes over wireless channels. All nodes can function, if needed, as relay stations for data packets to be routed to their final destination. In other words, ad-hoc networks allow for multi-hop transmission of data between nodes outside the direct radio reach of each other. Ad-hoc networks have distinct advantages over traditional communication networks. For example, ad-hoc networks can be more economical as they eliminate fixed infrastructure costs, and they can be more robust because of their non-hierarchical distributed control and management mechanisms. Adhoc networks increase mobility and flexibility, as they can be brought up and torn down in a very short time...
