Significance of Mobile AD-HOC Networks (MANETS)

Wireless networks use radio frequencies in air to transmit and receive data instead of using some physical cables. Wireless networks are formed of routers and hosts. In a wireless network, the routers are responsible for forwarding packets in the network and hosts may be sources or sinks of data flows .The fundamental difference between wired and wireless networks is the that the networks components communicate. A wired network relies on physical cables to transfer data. In a wireless network, the communication between different network components can be either wired or wireless. Since wireless communication does not have the constraint of physical cables, it allows a certain freedom for the host and/or router in the wireless network to move. This is one of the advantages of a wireless network.
