A wireless ad-hoc network is a collection of nodes which are self-organizing and self-administering in nature. All nodes are connected by wireless links and are free to move randomly. Thus, the network topology keeps on changing rapidly and erratically. These kinds of networks are very flexible and don't need any existing infrastructure. In order establish communication within the network and to discover the routes between the nodes a routing protocol is used so that messages may be delivered in a timely manner.
