Special Issue Information

Dear Colleagues,

Vehicular communications are seen as a key feature in the vehicle of the future. A connected vehicle has access to services that enable better safety and traffic efficiency while also providing information and entertainment (infotainment) to passengers. Communications are also an important tool for autonomous vehicles that need as much information about their surroundings as possible to travel safely.

Research and standardization efforts in the field of vehicular ad hoc networks (VANETs) have mainly focused on using a variant of Wi-Fi technology to communicate to vehicles (V2X, vehicle-to-everything): the IEEE 802.11 OCB (outside the context of a BSSID) mode. This mature technology is the basis for vehicular communication protocol stacks standardized in different regions of the world (e.g., ETSI ITS-G5 or IEEE/SAE WAVE). Moreover, different studies have proposed how to implement services for connected vehicles using this technology.

More recently, 3GPP has started to standardize solutions for the use of cellular technology in vehicular communications (C-V2X). This effort started in Release 14 (LTE), but it is expected that 5G will provide the necessary performance capability to support fully vehicular communications services. C-V2X enables the direct communication of 3GPP terminals with or without the assistance of the network.

Currently, several discussions considering technological, political, and business aspects are taking place about the convenience of using these two types of technology to enable vehicular communication services. In this Special Issue, we welcome articles analyzing the convenience of the application of any of these technologies to support particular services in connected vehicles. Articles comparing both types of technologies are especially welcome.

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

  • Communication technologies to support connected vehicles;
  • Standardization efforts in vehicular communications;
  • Network requirements for service support in VANETs;
  • Novel services for VANETs and how the network supports them;
  • Hybrid network solutions for VANETs;
  • Application of C-V2X to provide services in VANETs;
  • Application of protocol stacks based on IEEE 802.11 OCB to provide services in VANETs;
  • Comparison of the performance of C-V2X and protocol stacks based on IEEE 802.11 OCB;
  • Application of AI techniques in C-V2X and/or protocol stacks based on IEEE 802.11 OCB;
  • Network service for the autonomous vehicle;
  • Security in vehicular services (C-V2X- and IEEE 802.11 OCB-based);
  • Practical experiences with VANET deployments

This Special Issue solicits original theoretical and practical contributions, including review papers, on any area related to the application of communication technologies to the provision of services to connected vehicles.

Speeding up Discrete Event Simulations (DESs) is a broad research field. Promising Parallel Discrete Event Simulation (PDES) approaches with optimistic and conservative synchronisation schemes have emerged throughout the years. However, in the area of real-time simulation, PDESs are rarely considered. This is caused by the complex problem of fitting parallel executed DES models to a real-time clock. Hence, this paper gives an extensive review of existing conservative and optimistic synchronisation schemes for PDESs. It introduces a metric to compare their real-time capabilities to determine whether they can be used for soft or firm real-time simulation. Examples are given on how to apply this metric to evaluate PDESs using synthetic and real-world examples. The results of the investigation reveal that no final answer can be given if PDESs can be used for soft or firm real-time simulation as they are. However, boundary conditions were defined, which allow a use-case specific evaluation of the real-time capabilities of a certain parallel executed DES. Using this in-depth knowledge and can lead to predictability of the real-time behaviour of a simulation run. Full article
