Special Issue Information

Dear Colleagues,

It is a fact that an increasing number of vehicles on the market have some kind of interface that allows them to connect both to services offered by the manufacturer and services offered by third parties. Thus, we can stream music or videos through the car’s HMI, or obtain real-time information on the status of the route we are following.

In addition, this communication channel can allow us not only to receive information in the vehicle but also to use it as a data generator. Thus, we can consider the vehicle as a mobile sensor within a wireless sensor network (WSN). However, it is a network in which the nodes (the vehicles) can move at high speeds, and where the orography in which they move can make it difficult to transmit information to a server or service deployed in the cloud.

The advantages of using vehicles as sources and transmitters of information can be great, including assisting in traffic management operations, access control in cities, and environmental monitoring, to name but a few examples.

This Special Issue welcomes contributions dealing with all the technological facets of sensor networks for vehicular communications, including architecture, communication technologies, and advanced applications, sensing, and algorithms, but also on deployment issues, such as the development street or road side units to gather information from the vehicles.

The topics of interest include, but are not limited to the following:

  • Vehicle-to-sensor and sensor-to-vehicle communication architectures
  • Cooperative sensing applications in the scope of VANETs
  • Cooperative vehicle–infrastructure systems and architectures
  • Vehicular system and communication technologies
  • Networks optimization and QoS guarantee
  • Big data applications for sensor networks in the scope of VANETs
  • Sensor networks to improve autonomous vehicle perception
  • In-vehicle wireless sensor networks

Vehicle automation is driving the integration of advanced sensors and new applications that demand high-quality information, such as collaborative sensing for enhanced situational awareness. In this work, we considered a vehicular sensing scenario supported by 5G communications, in which vehicle sensor data need to be sent to edge computing resources with stringent latency constraints. To ensure low latency with the resources available, we propose an optimization framework that deploys User Plane Functions (UPFs) dynamically at the edge to minimize the number of network hops between the vehicles and them. The proposed framework relies on a practical Software-Defined-Networking (SDN)-based mechanism that allows seamless re-assignment of vehicles to UPFs while maintaining session and service continuity. We propose and evaluate different UPF allocation algorithms that reduce communications latency compared to static, random, and centralized deployment baselines. Our results demonstrated that the dynamic allocation of UPFs can support latency-critical applications that would be unfeasible otherwise. Full article

Vehicular Ad hoc Network (VANET) is a modern concept that enables network nodes to communicate and disseminate information. VANET is a heterogeneous network, due to which the VANET environment exposes to have various security and privacy challenges. In the future, the automobile industry will progress towards assembling electric vehicles containing energy storage batteries employing these resources to travel as an alternative to gasoline/petroleum. These vehicles may have the capability to share their energy resources upon the request of vehicles having limited energy resources. In this article, we have proposed a trust management-based secure energy sharing mechanism, named vTrust, which computes the trust degree of nodes to authenticate nodes. The proposed mechanism is a multi-leveled centralized approach utilizing both the infrastructure and vehicles to sustain a secure environment. The proposed vTrust can aggregate and propagate the degree of trust to enhance scalability. The node that requests to obtain the energy resources may have to maintain a specified level of trust threshold for earning resources. We have also evaluated the performance of the proposed mechanism against several existing approaches and determine that the proposed mechanism can efficiently manage a secure environment during resource sharing by maintaining average malicious nodes detection of 91.3% and average successful energy sharing rate of 89.5%, which is significantly higher in comparison to the existing approaches.

Key application of an intelligent transportation system is traffic safety, and it provides driver assistance. Safety messages are of two types, beacon messages and event messages. The nodes broadcast these messages in the vehicular networks. The system must rely on a robust medium access control (MAC) protocol to support delivery of safety messages. The standard medium access scheme that is used in vehicular networks to provide service differentiation to support various applications is IEEE 802.11p. The emergency event messages should reach the drivers immediately to take necessary steps to avoid casualties on the road. In IEEE 802.11p, both of these messages are considered with the same priority so that no separate differentiation is created. The proposed work focuses on improving the quality of service for forward collision warning applications in intelligent transportation systems. The scheme proposes a priority-based cooperative MAC (PCMAC) for channel access that works on the context of information. Simulation and analytical results validate improved performance of PCMAC in terms of packet delivery ratio, throughput, and average packet delivery delay, as compared with other eminent MAC protocols. The simulation results show that it has a 9% higher improvement in throughput than IEEE 802.11p and has better performance in the increasing number of emergency messages. Full article
