In this report, the problem of providing a geocast service in mobile ad hoc networks is considered and a novel geocasting algorithm combining unicast and flooding presented. Geocast is useful for sending messages to everyone in a specified geographical region. The proposed protocol is named "GeoTORA," because it is derived from the TORA (unicast) routing protocol. Flooding is also incorporated in GeoTORA, but it is limited to nodes within a small region. This integration of TORA and flooding can significantly reduce the overhead of geocast delivery, while maintaining high accuracy.
