An Anycast-Based Geocasting Protocol for Mobile Ad Hoc Networks.

The goal of geocasting protocols is to deliver data packets to a group of nodes that are within a specified geographical area, i.e., the geocast region. In an ad hoc environment, there are numerous scenarios which benefit from geocast communication. In this paper, the network is divided into grids, we propose a new routing protocol for geocasting, which combines anycast and flood. The proposed protocol utilizes the location information to route messages in grid-by-grid manner. The routing path by using proposed protocol is the shortest route between hosts in grids. The grid structure is successfully used to eliminate redundant transmission of geocasting messages. The time complexity of route discovery and the routing overhead are reduced. [ABSTRACT FROM AUTHOR]
