“…The 5th generation technology is already launched to tackle these cellular issues for vehicular communication. The implementation of 5G technology permits vehicular communication to manage traffic systems efficiently and adjust the traffic routes according to the situation by providing the best available routes towards destination [17]. The 5G cellular technology exploiting mmWave technology is fundamental to provide ultra-low latency services.…”

Reliable communications are essential to provide intelligent services to connected cars. For operational services, connected vehicles in VANET (Vehicle Ad hoc Networks) regularly transfer large amounts of data related to vehicular safety. Similarly, V2X (Vehicle-to-Everything) communications include vehicles exchanging information with each other and with infrastructure that is, Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V). This paper has analyzed the performance of IEEE 802.11p and 5G test network in a collaborative manner under realistic conditions. For performance analysis the exchange of safety-critical road weather and traffic information has been performed to enhance the traffic safety and traffic efficiency in the domain of intelligent transportation system (ITS). The vehicular connectivity is provided in V2V and V2I scenarios by utilizing short-range IEEE 802.11 standard or cellular approaches, such as the 5G network. Here, we consider combining these technologies in a cooperative manner to exploit jointly their advantages. In this cooperative heterogeneous network, the IEEE 802.11p supports safety-related pilot use cases while the provision of non-safety-related pilot use cases are supported by the 5G test network. The performance analysis revealed that the IEEE 802.11p performs quite reasonably well with restricted mobility in contrast of 5G test network in a collaborative manner to avoid road accidents.

“…Moreover, the provision of acceptable levels of services in case of faults, errors or targeted attacks are big challenges. Therefore, more than ever before, the new trends and technical enhancements in V2X communications need a holistic, robust, resilient and reliable architecture to tackle the current issues [21]- [26].…”

The new developments in mobile edge computing (MEC) and vehicle-to-everything (V2X) communications has positioned 5G and beyond in a strong position to answer the market need towards future emerging intelligent transportation systems and smart city applications. The major attractive features of V2X communication is the inherent ability to adapt to any type of network, device, or data, and to ensure robustness, resilience and reliability of the network, which is challenging to realize. In this work, we propose to drive these further these features by proposing a novel robust, resilient and reliable architecture for V2X communication based on harnessing MEC and blockchain technology. A three stage computing service is proposed. Firstly, a hierarchcial computing architecture is deployed spanning over the vehicular network that constitutes cloud computing (CC), edge computing (EC), fog computing (FC) nodes. The resources and data bases can migrate from the high capacity cloud services (furthest away from the individual node of the network) to the edge (medium) and low level fog node, according to computing service requirements. Secondly, the resource allocation filters the data according to its significance, and rank the nodes according to their usability, and selects the network technology according to their physical channel characteristics. Thirdly, we propose a blockchain-based transaction service that ensures reliability. We discussed two use cases for experimental analysis, plugin electric vehicles in smart grid scenarios, and massive IoT data services for autonomous cars. The results show that car connectivity prediction is accurate 98% of the times, where 92% more data blocks are added using micro-blockchain solution compared to the public blockchain, where it is able to reduce the time to sign and compute the proof-of-work (PoW), and deliver a low-overhead Proof-of-Stake (PoS) consensus mechanism. This approach can be considered a strong candidate architecture for future V2X, and with more general application for everythingto-everything (X2X) communications.

“…Unknown interference can cause packet collisions resulting in packet losses in actual communication schemes, e.g. in 11p, where collided packets are dropped [3]. The necessity of integrating reliability requirements in the physical domain of wireless communication motivates the information-theoretic investigations in this contribution.…”

Time diversity for reliable communication is examined in an information-theoretic framework by investigating information transmission over an Arbitrarily Varying Channel (AVC) under maximum error criterion and introducing the concept of block-restricted jamming. Positivity of the maximum error capacity of an AVC is directly related to the invertibility of the corresponding channel matrix. It is shown that reliable communication over an AVC without additional coordination is possible under block-restricted jamming using repetition coding.Index Terms-Reliable communication, unknown interference, arbitrarily varying channel, block-restricted jamming.
