Traditional wireless and cellular offer a limited range of mobile communication and are constrained in their deployment by their need for underlying network infrastructure. Demands for user mobility have created interest in the development of an emerging class of self organizing, rapidly deployable network architecture called Mobile Ad-hoc Networks. Mobile Ad-hoc Networks consist of several mobile nodes that are capable of communicating with each other without the use of a network infrastructure. Since MANETs are infrastructure less, each node acts as a router forwarding data packets to other nodes and it can be used for emergency situations like military applications, disaster relief and emergency services.
