Abstract
VANET is a special type of MANET which consists of moving vehicles as nodes that form a temporary network in an Adhoc fashion. In recent years, many protocols and techniques are available to share the traffic information in VANET. This study focuses on forwarding the road safety information from source vehicle to destination vehicle with RSU (Road Side Unit) and SP (Service Provider). RSU and SP are made to transmit the information to ongoing vehicles without missing the clarity and reliability. The main objective of this study is to find the reliable path from the source vehicle to destination vehicle to transmit the traffic information. Universal Generating Function Technique (UGFT) is one of the important techniques to assess the network reliability in real life. UFGT is applied to find the reliability of nodes and links used in this VANET. Results are obtained by using Network Simulator (NS-2). Simulation results show that information dissemination with RSU and SP outperforms without RSU and SP in terms of Delay, Throughput and Packet loss.
Highlights
VANET, a subclass of MANET, is a promising approach for future Intelligent Transportation System (ITS)
We introduced Service Provider (SP) and Road Side Unit (RSU) to take the responsibility for disseminating the information to ongoing vehicles on the roadside
This study proposes the method to calculate the reliability by using UGF techniques
Summary
VANET, a subclass of MANET, is a promising approach for future Intelligent Transportation System (ITS). Intelligent Transportation System is very important in terms of improving safety, user convenience of our personal and commercial travel. VANETs are considered as a highly dynamic version of MANET. Data exchanged in VANET may be Traffic/Road conditions, Accidents/Events and Commodity/Entertainment, Ad dissemination etc. Some drivers try to maximize their profit from the network by taking advantage of the network resources illegally. A selfish driver can tell other vehicles that there is congestion on the road ahead and they must choose an alternate route. This will cause severe damage via the applications available on the network and to the ongoing vehicles in the network
