“…These routing protocols uses forwarding concept of the protocol based on geographical location of the vehicles. A location service [30] like predictive hierarchical location service (PHLS) and global positioning system (GPS) are assumed to be implemented in vehicles to find out the location of the next node. The complete vehicular network is divided into a structure of hierarchal form of very small areas in PHLS.…”

Vehicular ad hoc network (VANET) is an emerging category of mobile ad hoc networks (MANET). It is a collection of vehicles rather than mobile nodes to communicate with other vehicles and road side infrastructure units. Because of constraint road patterns and very high speed of vehicles, routing is a challenge in VANET. Most of the authors analyzed the performance of topology based routing protocols. This paper analyzed the performance of location aided routing (LAR) and zone routing protocol (ZRP) geographical protocols for city environment. Real time traces of vehicular movements are generated using a traffic simulator-VanetMobiSim with intelligent driver model (IDM). Packet delivery ratio, throughput, average delay, normalized routing load and lost packet ratio metrics are used to evaluate the performance of LAR and ZRP using ns2 along with IEEE802.11p. The analysis of results is performed using AWK programming script.

“…There is a growing body of work that uses location information for routing in MANETs and numerous protocols for location services [7,8,9,10,11,12,13,14,15,16,17,18,19] have been proposed to solve location tracking. [20] provides a recent survey and presents a qualitative comparison of different location services found in the literature of MANETs, while [21,22] provide a realistic, quantitative analysis comparing the performance of some location services.…”

Position-based routing protocols take advantage of location information to perform a stateless and efficient routing. To enable position-based routing, a node must be able to discover the location of the messages' destination node. This task is typically accomplished by a location service. Recently, several location service protocols have been developed for ad hoc networks. In this paper we propose a novel location service called PHLS: Predictive Hierarchical Location Service. In PHLS, the entire network is partitioned into a hierarchy of smaller and smaller regions. For each node, one node in each-level region of the hierarchy is chosen as its local location server. When the network initializes or when a node attaches the network, nodes contact their local location server with their current location information (ie. position and velocity). Then, they only need to update their location server when they move away from their current region. Finally, nodes query their location servers and get the exact or predicted location of destination nodes.Comment: 14 Pages, IJCNC Journa
