This paper presents a definition, the design space, three reasonable implementations, and an ns-2 simulation study of a new type of geocast protocol, called stored geocast. A stored geocast is a time stable geocast, which is delivered to all nodes that are inside a destination region within a certain period of time. When used in a mobile ad hoc network (MANET) it allows to realize a persistent message valid for a certain geographic region, possibly combined with a time limit. Stored geocast is of particular interest in the automotive domain, since it allows realizing virtual traffic signs or for location-based services in general. The simulation results investigate the delivery success ratio and the resulting message overhead in several scenarios with random waypoint movement and in realistic vehicular traffic scenarios gathered from a driver behavior simulator.
