A replica distrubution scheme for location-dependent information on vehicular ad hoc networks

In this paper we propose Road-aware Skip Copy (RSC) method for distributing replicas of location-dependent data on server-less vehicular ad hoc networks in urban areas. In the RSC method, mobile nodes broadcast replicas of data item near intersections in order to distribute replicas to many nodes with small number of broadcasts, and it limits the number of the holder of the replicas by the hop count from the source nodes in order to save the storage. The results of simulations using real map data show that the RSC method achieves higher access success rate than those of conventional methods.
