Abstract
This paper suggests a new geocasting protocol which is used to transfer the geographic packets to the specific region in MANET. Geocasting protocol is basically different from the conventional multicasting protocol that needs group addition and maintenance. A geocasting protocol using the mobile node's position information is the new area of multicasting protocols. The existing geocasting protocols have the following problems; it may be impossible to transfer data to some mobile hosts even if there are alternate routes and they have low adaptability and efficiency when the number of mobile hosts increases. The proposed CBG (Cluster-Based Geocasting) uses the proactive routing strategy and clustering technique with mobile host's location information. The CBG achieves high successful data transmission ratio and low data delivery cost to mobile hosts at specific region.
