Intersection-Based Routing Protocol for VANETs

2015

Wireless Netw

Routing protocols in vehicular ad hoc network (VANET) mainly depends on the correct information provided by the neighbor vehicles in the form of beacons. If the on board unit is soft faulty, it provides incorrect data and reduces the performance of the system. In this paper, a novel self soft fault detection based routing protocol is proposed for VANET in city environment to send the data quickly to the destination by detecting the soft faulty vehicles. The vehicle itself detects whether it is soft faulty or fault free by using the decisions made by the neighbor vehicles and exclude itself from the routing process. The data is forwarded through the fault free vehicles in a mostly connected path. The best path is selected at every junction by finding path values for the paths connected to the junction. The path with the minimum path value is selected as the next path through which the data is forwarded. The performance of the fault detection method is evaluated by fault detection rate and false alarm rate. Simulation results show that, proposed protocol performs better than GyTAR, A-STAR, P-GEDIR, and GSR routing protocols in terms of end-to-end delay, number of network gaps, and path length.

“…Chou et al [24] proposed an intersection based routing protocol, where an intersection with the minimum delay is selected as the next intersection through which the data is forwarded. To calculate the data transmission delay from one junction to another, the authors uses the forwarding delay and carrying delay.…”

A Road Selection Based Routing Protocol for Vehicular Ad Hoc Network

2015

Wireless Pers Commun

Vehicular ad hoc network is an advanced wireless communication technology to provide intelligent transportation system services to the drivers and passengers. High mobility of vehicles in the network creates gaps between the vehicles, which reduces the performance of the system. If network gaps in a path are predicted earlier before sending the data, then the performance of the system increases. In this paper, a novel position based routing protocol is proposed to send the data quickly from the source to the destination. This is performed by selecting a best road from a junction to the neighbor junction. The road is selected by calculating road ratings for each road connected to the junction. A recovery method is proposed to connect the vehicles which suffers from the network gap problem by adjusting the speed of the sufferer vehicles. Simulation results show that, proposed method performs better than P-GEDIR, GyTAR, A-STAR and GSR routing protocols in terms of average end-to-end delay, network gap encounter and number of hops.

“…Intersection Based Routing (IBR) [54] protocol uses the junction with minimum delay. The delay is the total of forwarding delay, carrying delay, and queuing delay.…”

RVCloud: a routing protocol for vehicular ad hoc network in city environment using cloud computing

2015

Wireless Netw

Routing in Vehicular Ad hoc Network (VANET) is a challenging task due to high mobility of vehicles. In this paper, a RVCloud routing protocol is proposed for VANET to send the data efficiently to the destination vehicle using cloud computing technology. In this protocol, vehicle beacon information is send to the cloud storage through the Road Side Unit (RSU). As vehicles have less storage and computing facility, the information of all the vehicles moving in the city is maintained by the cloud. Source vehicle sends the data to the destination by sending the data to the nearby RSU. After receiving the data, RSU sends a request to the cloud for an optimal RSU information, that takes minimum packet forwarding delay to send the data to the destination. Cloud provides location service by providing destination location and optimal RSU information. Then RSU sends the data to the optimal RSU using internet. By using the internet facility, packet forwarding delay and link disruption problem are reduced. Simulation results show that, RVCloud performs better than VehiCloud, P-GEDIR, GyTAR, A-STAR, and GSR routing protocols.
