An Ad Hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Nodes in mobile and ad hoc network communicate with one another via packet radios on wireless multihop links. Because of node mobility and power limitations, the network topology changes frequently. Routing protocols therefore, plays a important role in mobile multihop network communications. Routing protocols used inside ad hoc must be prepared to automatically adjust to an environment that can vary between the extremes of high mobility with low bandwidth and low mobility with high bandwidth.
