Generally, the unicast and the multicast routing protocol are used to deliver messages between randomly chosen nodes. The major problem with these type of routing is that they do not process the distributed information's. Several algorithms or protocols such as shortest routing protocol and position based protocol are found to ensure effective routing in sparse network. These techniques focus on delivering the messages to certain nodes. However these techniques or protocols limit the process of retaining the information regarding the missing nodes. The proposed boomerang protocol effectively receives the messages from the nodes at any geographical area. The boomerang protocol attempts to utilize the physical location based information to increase the performance of geo cast delivery. A unique feature of this protocol is that it records the geographical trajectory while moving away from the origin, thus paving a way to exploits the recorded trajectory in case of returning back. This protocol simply attempts to provide more efficient routing method while maintaining the information of the missing node. Boomerang protocol finds a wide application in LAN, WAN, and other mobile communication network.
