With the development of internet vehicles, traditional centralized content caching mode transmits through core network, which causes a large delay and cannot meet demands for delay-sensitive services. To solve these problems, on basis vehicle we propose an edge collaborative scheme. Road side unit (RSU) mobile computing (MEC) are used to collect information, predict cache popular content, there...

In recent years, the development of the Intelligent Transportation System (ITS) has increased the popularity of vehicular ad hoc networks (VANET). A VANET is designed to enable vehicles to exchange information about traffic or vehicle conditions to help other vehicles avoid traffic accidents or traffic jams. To resist malicious attacks, all vehicles must be anonymous and their routings must be ...

Abstract: We propose and analyze a MAC Protocol for multiple service channels (SCHs) based on reservation by distributed coordination function (DCF) on control channel (CCH) for IEEE 802.11p and IEEE 1609.4 wireless access in vehicular environments (WAVE) networks. Specifically each user sends a request for service (RFS) packet to the Road-Side Unit (RSU) on the CCH by DCF method in order to re...

A vehicular ad hoc network (VANET) is a mobile composed of communication between vehicles, vehicles and roadside units, pedestrians, in order to achieve traffic safety entertainment services. The design the routing protocol very important for realization service function VANET. Local optimum congestion problems are restraints traditional geographic protocols In this paper, software-defined (SDN...

Connected vehicles in vehicular networks will lead to a smart and autonomous transportation system. These have large number of applications that require wireless connectivity by using cellular vehicle-to-everything (C-V2X). The infrastructure C-V2X comprises multiple roadside units (RSUs) provide direct with the on-road vehicles. Vehicular traffic are mainly categorized into three major groups ...

VANET (Vehicular adhoc network) this provide intelligent service to the real time road information by using navigation service. Service support is required to reach specific destination. The RSU (road side unit) is use to find best route and also source information can be authenticated using real-time road information. Security services provide protection to driver and support to query of drive...

As an important direction of topology management and infrastructure construction in Internet Vehicles (IoV), the problem roadside unit deployment has been discussed a lot. Considering communication occlusion caused by mobile vehicles, novel multi-objective optimization under constraints target road coverage reliability is proposed this paper. Firstly, traffic flow model vehicle introduced, chan...
