Improving Geo-casting by Combining Any-cast and Hovering Information

Geocasting is a variation on the notion of multicasting in which messages are deliver to the nodes residing in a specific area. This paper proposed a novel geocast protocol based on any-cast and hovering information in order to improve the performance by balancing load between server and local nodes. Thus proposed technique has two phases for geocasting, 1) any-cast from source to geocast region and 2) distribution of messages using hovering information. Our results has shown that using hovering information and creating replicas for geocasting messages we can reduce the overhead of broadcasting messages several time that helps in reducing the bandwidth.
