The MANET in wireless sensor networks is preferred because of its mobility and scalability. This makes the use of MANETs in wide range of applications. The important criteria of the MANETs are its decentralized architecture. It does not require fixed infrastructure such as a base station for its operation. Instead it requires mobile nodes for transmitting the messages among the network. MANET is a collection of nodes connected with a wireless links either directly or indirectly. These nodes have ability to communicate among themselves by maintaining their mobility. Another important criteria of MANETs is its ability of self configuring.
