The fast topology changes in vehicular ad hoc networks (VANETs) may be caused by fading of the wireless link as well as mobility of nodes. Link stability is often measured using mobility parameters (e.g, location, velocity, direction), and disregarding multipath fading of the signal. This may cause network performances degradation. In this paper, we have improved the relay selection scheme by integrating...
Vehicular Ad Hoc Networks (VANETs) offer great prospects for the future intelligent transportation system (ITS), which are receiving much attention thanks to the wide variety of services they can provide a lot of work and research around the globe is being conducted to define the standards for VANETs, which depend on the vehicles themselves to provide network functionality rather than the traditional...
This paper designs a new scheme based on Controlled Vehicular Internet Access (CVIA), a protocol that divides a straight road into several segments. To avoid hidden nodes and reduce unnecessary CTS/RTS, vehicles send the packet to the road side unit (RSU) segment by segment. The features of CVIA include its high end-to-end throughput and fairness between road segments. However, a significant problem...
The ability to realize an Intelligent Transportation System (ITS) to improve driver safety has attracted huge interests from researchers this decade. Vehicular Communication covering vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) communication supported by ITS provide ubiquitous internet connectivity among the vehicles to improve safety for drivers. In addition to carrying driver safety...
The Internet access from vehicular networks is gaining great interest from the research community. In fact, vehicles should be able to connect to the Internet and communicate with different networks through gateways. Guaranteeing safety on the roads is the main objective of vehicular networks. Safety applications need to collaborate with other types of services for efficient safety assurance. Consequently,...
