Abstract

The primary work of vehicular ad hoc network (VANET) is to route the packets and to can handle a high mobility of vehicles in the frequently changing topology. The fast dynamic changing topology is the major problem in VANET, so it is necessary to compute the link estimation time (LET) of every relay node in the network. The LET is one of the recent research finding to solve VANET routing issues. This paper depicts the overall survey of different V2V (or) V2I link estimation techniques developed for VANET and also compare the Position based protocol, cross-layer and prediction based protocol. The objective of this paper is to analyse the performance of the different protocols by applying various types of LET in terms of speed, distance and signal and noise rate (SNR) using NS3. The results show that cross-layer protocol has significant performance than comparing to other routing protocols in VANET with the help of plotted graph.
