GOAL: A Parsimonious Geographic Routing Protocol for Large Scale Sensor Networks

Geographic routing protocols have attracted significant attention from the Wireless Sensor Network (WSN) research community, because they are simple and scalable. In geographic routing, a source node obtains the location of a destination node from a location service, or through a hash-function in a data centric storage scheme. A packet is then forwarded to the neighbor that is geographically closest to the destination. This greedy approach allows near-optimal path length in uniform and dense networks without obstacles (i.e., network holes).
