Wireless communication is indispensable to Internet of Things (IoT). Carrier sensing multiple access/collision avoidance (CSMA/CA) is a well-proven wireless random access protocol and allows each node of equal probability in accessing wireless channel, which incurs equal throughput in long term regardless of the channel conditions. To exploit node diversity that refers to the difference of channel...
In this paper, an approach was proposed based on coalitional games to solve the problem that packets of boundary nodes cannot be forwarded. This approach can effectively motivate backbone nodes to forward packets for the boundary nodes. In order to prevent "monopoly" behavior of backbone nodes, we proposed auction mechanism for competition using auction theory. Finally, we develop a packet-forwarding...
Inter-vehicle communication among great deals of vehicles plays an important role in providing a high level of safety and convenience to drivers. Geographic routing protocol has been identified to be suited as a result of the special nature of vehicular ad hoc networks (VANETs), such as high dynamic mobility and large network size. Although there is considerable functional research about geographic...
Vehicle-to-vehicle communication among vehicular ad hoc networks (VANETs) plays an important role in providing a high level of safety and convenience to drivers. Geographic routing protocol has been identified to be suitable for VANETs because of the special nature of such networks, e.g., frequently changed network topology and high dynamic mobility. There is considerable functional research about...
Developing routing protocol for vehicular ad hoc networks (VANET) is a challenging task due to potentially large network sizes, rapidly changing topology and frequent network disconnections, which can cause failure or inefficiency in traditional ad hoc routing protocols. We propose an adaptive connectivity aware routing (ACAR) protocol that addresses these problems by adaptively selecting an optimal...
Multi-hop car to car communications are useful for supporting many vehicular applications that provide drivers with safety and convenience ranging from office on the wheel to real traffic query, vehicle safety, parking space searching and on-road advertisement. Developing multi-hop communication in vehicular ad hoc networks (VANET) is a challenging problem due to the rapidly changing topology and...
