Location server selection techniques in vehicular ad-hoc network

In Vehicular Ad-Hoc Networks (VANETs), location service protocol is utilized to locate locations of nodes to be used by position-based routing algorithms before the start of communication between source and destination. The existing location services proposed for Mobile Ad-Hoc Networks (MANET) suffer from poor scalability in VANET environments. Due to importance of positioning in VANET environment and reliability of number of applications on locations of mobile nodes, Location-Based service protocols designed for VANET is increasing. Providing locations in challenge and rapid changing topology such as VANET need to be up-to-date, accurate retrieved with low latency and low overhead. This paper reviews critically the proposed techniques for selecting location server of location- based protocols for VANET environment
