Abstract Air pollution is a Worldwide challenge that reason for premature death. It affects both developing nations and developed nations. In particular, the air so much polluted cities are fighting to fulfill quality range protect humans from harmful substances. One of greatest global challenges 2050 reduction greenhouse gas emissions. Besides emissions, major problems in many urban areas this...

Vehicular-to-anything (V2X) technology is attractive for wireless vehicular ad-hoc networks (VANETs) because it allows for opportunistic choice of a vehicular protocol between vehicular-to-vehicular (V2V) and vehicular-to-infrastructure (V2I) communications. In particular, achieving seamless connectivity in a VANET with nearby network infrastructure is challenging. In this paper, we propose a d...

With the development of IoT, Vehicular Ad-hoc Network will be shifted to Vehicular Ad-hoc Network managed cloud in near future. As the traditional cloud, VMM is a crucial problem in Cloud Based Vehicular Networks. Due to the distinct feature of high mobility, VMM Cloud Based Vehicular Networks need to be addressed to keep cloud services running on. When a vehicle moves on the road, it moves out...

In this paper, we develop a novel link reliability model for vehicle ad hoc networks, which consist of vehicular wireless mobile terminals. In order to accurately present the vehicular mobility of the node, classic traffic theory is applied that discards the dependence on different vehicular mobility scenarios. Road density and terminal relative speed are introduced in our model. We demonstrate...

With growing interest in using cognitive radio (CR) technology in wireless communication systems for vehicles, it is envisioned that future vehicles will be CR-enabled. This paper discusses CR technologies for vehicular networks aimed at improving vehicular communication efficiency. CR for vehicular networks has the potential of becoming a killer CR application in the future due to a huge consu...

With the rapid growth and evolution of the vehicular network with the highly increasing demand of vehicular traffic management, vehicular infotainment applications, and the vehicular cloud computing, massive vehicular information is required to be downloaded from roadside-deployed gateways. With the nature of high mobility and intermittent connectivity, it is challenging to provide a highly rel...

With an increasing number of vehicles with significant computing and communication, many applications such as vehicular Internet hot-spots, digital and entertainment content’s broadcast, Intelligent Transportation Systems applications, and highway management will become possible. This “vehicular mobile commerce” will actively involve vehicles and users in both extending the existing mobile comm...

In Inter-Vehicular Adhoc Network (IVAN) does not have a fixed network topology but is highly dynamic. The topology of the network changes frequently because wireless links are established and broken down due to certain factors such as the velocity of the vehicles, their mobility patterns and their spatial density. These high dynamics also cause very short times for data transfer. This paper pre...

Vehicular emission (VE) is one of the important anthropogenic sources for airborne carbonyls in urban area. Six types of VE-dominated samples were collected at representative locations in Hong Kong where polluted by a particular fueled type of vehicles, including (i) a gas refilling taxis station (liquefied petroleum gas [LPG] emission); (ii) a light-duty passenger car park (gasoline emission);...
