“…It is a name we have chosen to identify a protocol class that is briefly described in [18]. This protocol encompass two phases: the unicast forwarding from the initial sender until the first node inside the destination region is reached, and the flooding inside the destination region.…”

Geocasting is the delivery of a message to nodes within a geographical region. With geocast, new services and applications are feasible, such as finding friends who are nearby, geographic advertising, and accident or wrong-way driver warning on a motorway. In this article we present a survey on geocast routing protocols. The protocols mainly differ in whether they are based on flooding, directed flooding, or on routing without flooding, and whether they are suitable for ad hoc networks or for infrastructure networks. Based on these criteria we propose a classification of geocast protocols. Our protocol comparison includes message and memory complexity, robustness, and the ability to deliver geocast packets in partially partitioned networks. Finally, we present simulations to compare the approaches based on flooding, directed flooding, and routing without flooding.

“…Uni cast forwarding can be realized with any available unicast pro tocol. For example, in [18] a position-based greedy routing algorithm that was derived from GPSR [9] is used. The uni cast destination is selected to be the center of the geocast des tination region.…”

“…Once a message reaches its destination region, the receiver broadcasts the message to all of its neighbors within the region. For instance, in [16], Maihofer et al propose using general unicast routing approaches to forward messages to the destination area. Each node on the unicast forwarding path checks whether it is in the geocast destination region.…”

“…Although several data forwarding approaches have been proposed [4,6,9,11,12,14,16,18], they are not specialized for VSN applications, and they do not consider the fact that, in VSNs, the geocast destination region is usually centered at the event source.…”
