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...

Smart City comprises numerous technologies and depends on sensors to be aware of its environment. Vehicular sensing where vehicles on the road continuously gather, process, and share location-relevant sensor data (e.g., road condition, traffic flow) is emerging as a new network paradigm for sensor information sharing in urban environments. In this chapter, we introduce the vehicular network and...

In this paper, the lattice vehicular model, which is in the form the lattice Boltzmann equation is directly derived from the Boltzmann equation. It is shown that the lattice Boltzmann equation is a special discretized form of the Boltzmann equation. A 3-bit approximation, which describe uncongested traffic flow, for the discretization of the Boltzmann equation in both time and phase space is di...

Vehicular Ad-hoc Networks (VANETs) are the most prominent enabling network technology for Intelligent Transportation Systems(ITS).VANETs provides many new exciting applications and opportunities albeit transportation safety and facilitation applications are their core drivers. Security of vehicular networks remains the most significant concern in VANETs deployment – because it is mandatory to a...

Among civilian communication systems, vehicular networks emerge as one of the most convincing and yet most challenging instantiations of the mobile ad hoc networking technology. Towards the deployment of vehicular communication systems, security and privacy are critical factors and significant challenges to be met. Thanks to the substantial research efforts carried out by the community so far, ...
