Data Transmission in Mobile Ad Hoc Network Using Multicast Routing Protocol

In mobile ad hoc networks, when a mobile host receives a data request from another host, the host usually transmits the requested data item by unicast. However, if mobile hosts hold data items that are frequently requested by others, they have to transmit the data items many times and consume a large amount of power. In this research work, i propose a data transmission method for not only maintaining data availability but also reducing traffic for data access. In this proposed method, each mobile host sends a data request attached with the deadline to receive the requested item by the determined time. Moreover, each mobile host collects multiple requests for data items and transmits the requested data items by multicast, and thus, reduces data traffic. Multicasting plays a crucial role in many applications of mobile ad hoc networks (MANETs).
