Vehicular emission is a major environmental health problem in the world today especially developing countries including Nigeria. This study was centered on assessing vehicular emissions pollutants such as Carbon monoxide (CO), Hydrogen Sulphide (H2S), Formaldehyde (HCHO) and Total Volatile Organic Compound (TVOC) Benin City, Edo State, The sampling of CO H2S gaseous done using H-4S gas analyzer...

During the last few years, continuous progresses in wireless communications have opened new research fields in computer networking, aimed at extending data networks connectivity to environments where wired solutions are impracticable. Among these, vehicular communication is attracting growing attention from both academia and industry, owing to the amount and importance of the related applicatio...

Greenhouse gas (GHG) emissions from the global shipping sector have been increasing due to economic growth. The International Maritime Organization (IMO) has set a goal of halving GHG by 2050 as compared with 2008 levels, and responded introducing several international regulations reduce maritime transportation. impact emissions’ regulation measures curb them evaluated in IMO’s studies. However...

This study assessed pollutants concentration at selected markets in Owerri. These were purposively after careful consideration of all major the area; considered to be more congested during day as a result open assess road junctions coupled with high density vehicular movement, presence offices, residential buildings, and human activities. Five air from emissions monitored, namely: carbon monoxi...

In vehicular-to-roadside (V2R) communications of vehicular network, the bandwidth from roadside unit (RSU) can be shared among vehicular users to improve the utilization and reduce the cost. In this paper, the coalition game is formulated to model the situation in which multiple vehicular users can cooperate to share the bandwidth to RSU. First, the rational coalition formation is considered in...

The successful deployment of vehicular ad hoc networks (VANETs) has to overcome the serious security threats which impair the operation of different vehicular applications. This paper presents the vulnerabilities of vehicular ad hoc networks and analyzes some of the security problems inherent in VANETs and also presents proposed solutions to overcome some of the vulnerabilities and security pro...

A vehicular ad hoc network (VANET) is a type of mobile network whose nodes are traveling cars which communicate with one another using short-range wireless communications. These cars can exchange and share different information among them, which can lead to the development of interesting applications that require the cooperation of vehicles or using the vehicular network as a distributed comput...

Trust is a useful model for the interactions of Vehicular Ad Hoc Network (VANET) in Vehicular Cyber-Physical System (VCPS). Given a dynamic nature in transportation, traditional static trust models cannot effectively create the trust relationship among moving vehicles, and cannot handle quickly and dynamically the frequent vehicular interactions in a network topology. A novel trust model of VAN...

In this paper, we investigate the performance of LTE Multicast-Broadcast Single-Frequency Networks (MBSFN). LTE-MBSFN is viewed as one of the most promising candidates for vehicular communications which can enhance reliability of vehicular application traffic. This is achieved due to the possibility to efficiently support message exchange in-between vehicles by multicasting information to sever...
