Abstract
In Vehicular Ad hoc Networks (VANETs) the mobility of the nodes is the main concern. This mobility of nodes makes the route unstable andunreliable for the information exchange and communication between two nodes in the network. To enhance the performance and throughput of the VANETs, routes between nodes must be reliable and stable. In this paper, we study the significance of path durationand link duration in Vehicular Ad hoc Networks (VANETs).Because of this mobility, connectivity graphs changes very frequently and it affects the performance of VANETs. Therefore, path duration can be used to predict the behaviour of the mobile nodes in the network. Estimation of the path duration in VANETs can be a key factor to improve the performance of the routing protocol. Estimation of path duration is a challenging task to perform as it depends on many parameters including node density, transmissio n range, numbers of hops, and velocity of nodes. This paper will provide a comprehensive study for estimating the path duration in VANETs.
Highlights
Vehicular Ad hoc Networks (VANETs) is a subclass of Mobile Ad hoc Networks (MANETs)
VANETs are the special subclass of MANETs but some of the parameters are very different in VANET when we do comparison
VANETS are fast moving ad hoc network, so MANETs routing protocols are not able to provide the maximum throughput with VANETs
Summary
VANET is a subclass of Mobile Ad hoc Networks (MANETs). VANETs are special in the sense of their mobile nodes, these nodes are vehicles on the roads and the mobility of these vehicles is very high. VANETs are real time network, used in the daily life or practically on the roads. The increasing traffic on the roads causes accidents and a matter of concern worldwide. Increasing vehicular crime is an important issue for the nations worldwide. These accidents and crimes cause loss to life, economy, and security of human beings. VANETs will help in making the road safer and well organized in future. The Intelligent Transportation System (ITS) has been working since long time to make the road safe, secure, and has improved efficiently in way to travel and transportation [1]. DSRC service is using the 5.850-5.925 GHz for the communication between vehicles-to-vehicles (V2V) and vehicles to road-side units (V2R)
