Efficient location management is one of the major challenges in Vehicular Ad Hoc NETworks (VANETs). Due to the high mobility of vehicles and the increase in their number, the location information updating and querying messages will consume the limited bandwidth of VANETs. This involves the development of a scalable and locality-aware location service management protocol. In this paper, the authors propose a promising solution called the Modified Region-based Location Service Management Protocol (MRLSMP), which utilizes the existing infrastructure on the road as a location management service entity. To evaluate the efficiency of their proposal, they compare their scheme with existing solutions using both analytical and simulation approaches.
