Challenges and Opportunities in Vehicular Cloud Computing

Abstract

Vehicular ad-hoc networks (VANET) have become an important research area due to their ability to allow sharing resources among the users to carry out their application and provide services of transport and traffic management. VANET communication allows exchange of sensitive information among nearby vehicles such as condition of weather and road accidents in order to improve vehicle traffic efficiency through Intelligent Transportation Systems (ITS). Many technologies have been developed to enhance ITS. Recently, vehicular cloud computing (VCC) has been developed in order to overcome the drawbacks VANET. VCC technology provides low-cost services to vehicles and capable of managing road traffic efficiently by using the vehicular sources (such as internet) to make decisions and for storage. VCC is considered as the basis for improving and developing intelligent transportation systems. It plays a major role in people's lives due to its safety, security, trust, and comfort to passengers and drivers. This chapter investigates the vehicular cloud computing. The authors first concentrate on architectures. Then, they highlight applications and features provided by VCC. Additionally, they explain the challenges for VCC. Finally, the authors present opportunities and future for VCC.

Performance Evaluation of Downlink Coordinated Multipoint Joint Transmission under Heavy IoT Traffic Load

“…FI indicates of fairness degree in the assigned rates or throughput performance between users in the network. The FI value ranges from zero to one, where FI = 1 means all IoT nodes have equal throughput on average [32]. In JT-CoMP, a UE is served by multiple TPs depending on the received signal powers from the different transmitters.…”

“…Accordingly, the percentage of users that have average spectral efficiency for intrasite is less than the percentage of users that have average spectral efficiency for intersite. In addition, when the number of users increased, the UE spectral efficiency decreased in the two cases of intersite and intrasite CoMP because the network resources will be divided on a larger number of users as in throughput [32].…”

An Effective and Secure Key Management Protocol for Message Delivery in Autonomous Vehicular Clouds

“…Hussain [ 13 ] in 2012 proposed a three-architecture framework including vehicular clouds, vehicles using clouds (VuC), and hybrid vehicular clouds (HVC). Ahmed [ 3 ] in 2018 proposed a novel privacy-preserving mechanism for VCs. In this paper, the authors focus on the architecture and highlight applications and features in VCs.…”

“…VCC is a new paradigm that has a prominent impact on traffic management and road safety [ 2 ] and it has been developed to overcome the drawbacks in VANET. Nowadays, VCC is considered as the key measure to improve and develop ITS [ 3 ].…”

“…In the study of AVCs, most studies only focus on the security challenges [ 2 , 3 , 7 , 8 ], the architecture and traffic flow control [ 1 , 9 , 10 , 11 , 12 , 13 ], but in the literature, just a few studies have addressed a specific solution to these security challenges in AVCs. Furthermore, among these existing protocols in the active network, most of them have addressed authentication but fail to propose an authentication as well as confidentiality protocol.…”
