Secure Location-Aided Routing Protocols With Wi-Fi Direct For Vehicular Ad Hoc Networks
Secure routing protocols are proposed for the vehicular ad hoc networks. The protocols integrate the security authentication process with the Location-Aided Routing (LAR) protocol to support Wi-Fi Direct communications between the vehicles. The methods are robust against various security threats. The security authentication process adopts a modified DiffieHellman key agreement protocol. The Dif...
متن کاملImproving Performance of Opportunistic Routing Protocol using Fuzzy Logic for Vehicular Ad-hoc Networks in Highways
Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...
متن کاملInter-Vehicular Communications Using Wireless Ad-Hoc Networks Comunicación inter-vehicular utilizando redes ad-hoc inalámbricas
This paper proposes a new routing algorithm to facilitate communication in highly mobile wireless ad-hoc networks for motorway environments with no physical infrastructure which undergo frequent topological changes. This new reactive routing algorithm for inter-vehicular communication is based on location information in which the source node ascertains the position of its communication partner ...
متن کاملExperimental Characterization of Communications in Vehicular Ad Hoc Network Experimental Characterization of Communications in Vehicular Ad Hoc Network
Majority of characterization studies on Vehicular Ad Hoc Network (VANET) are based on simulations that assume little network errors and consistent signal strength. Existing VANET experiments, on the other hand, focus mostly on single-hop communication and they are conducted with external antennas or other built-in equipments in small areas. This thesis surveys the challenges in VANET and conduc...
متن کاملWi-Fi Assist: Enhancing Vehicular Wi-Fi Connectivity with an Infrastructure-driven Approach
Vehicles access the Internet via cellular networks, instead ofWi-Fi networks. This choice has been mostly justified by the ubiquitous coverage of cellular networks: Wi-Fi coverage has been shown to be inadequate in the past, even in urban areas. We argue that providing Internet connectivity to vehicles via WiFi is worth a revisit. Motivated by improvements inWi-Fi network coverage in recent yea...
