Previous research has illustrated that location-based routing protocols improve the effectiveness of mobile ad hoc network (MANET) routing. The goal of a location server, which may be used in conjunction with a location-based routing protocol, is to provide accurate location information on the mobile nodes in the network. In this paper, we propose an information dissemination protocol called LEAP (legend exchange and augmentation protocol), which we use to implement a location server for a MANET. We compare our legend-based location server to three other location service alternatives via extensive simulations, and illustrate that our LEAP implementation offers both effective accuracy and low overhead.
