Geocasting is a mechanism to disseminate data messages within a certain geographical region. Since packet forwarding is based on the location information of nodes, it is known to reduce the path maintenance cost significantly. The geocasting can be suitable for several applications in tactical ad hoc networks, such as an event to alarm enemy's missile attack, guerilla appearance, or local weathercast...
This paper considers the problem of geocasting in mobile ad hoc networks. Geocasting, a variation on the notion of multicasting, is a mechanism to deliver messages of interest to all nodes within a certain geographical target region. Although several geocasting protocols have already been proposed for mobile ad hoc networks, with the goal of achieving an efficient message delivery, most of these algorithms...
