Analysis of Road Vehicle Density based VANET Routing Protocol in City Environments using QualNet
Abstract: During the last few years; continuous progresses in wireless communications have opened new research elds in computer networking; aimed at extending data networks connectivity to environments where wired solutions are impracticable. Among these; vehicular trafc is attracting a growing attention from both academia and industry; due to the amount and importance of the related applications; ranging from road safety to trafc control; up to mobile entertainment. Vehicular Ad-hoc Networks (VANETs) are self-organized networks built up from moving vehicles; and are part of the broader class of Mobile Ad-hoc Networks (MANETs). Because of their peculiar characteristics; Vanets require the denition of specic networking techniques; whose feasibility and performance are usually tested by means of simulation. In this paper; we have evaluated the road vehicle density based Vanet routing protocol in city environment where each vehicle computes the vehicle density of the road to which it belongs by using beacon messages and the road information table. Based on the real-time road vehicle density information; each vehicle establishes a reliable route for packet delivery. Finally; the performance of this routing mechanism is evaluated through QualNet 5.0 and it is observed that this routing mechanism performs well in terms of packet delivery and throughput.
