“…Two of the most promising classifications developed for TDMA-based contention-free MAC protocols are centralized and distributed schemes [ 18 , 30 ]. In centralized TDMA-based contention-free MAC protocols, the central coordinators, i.e., roadside units (RSUs) or cluster heads (CHs), allocate and control message forwarding in the network [ 22 , 31 , 36 ]. In the RSU-based approach, RSUs act as intermediate relays for inter-cluster communication.…”

“…Since a large number of RSUs are required to facilitate high traffic, this approach is not suitable for highway roads [ 37 ]. For the cluster-based approach, the clusters have to form and change over time in high-mobility scenarios, and the dramatic change in vehicle mobility has an impact on cluster stability due to cluster splitting and merging, which results in consequential network overheads and performance degradation [ 22 , 36 , 38 ].…”

“…In distributed TDMA-based contention-free MAC protocols, the cooperative communication-based method is an excellent way to improve transmission performance in high-density traffic as compared to low-density traffic [ 17 , 35 ]. Based on this, [ 20 , 22 , 24 , 39 , 40 ] propose increasing channel capacity in VANETs and satisfying the latency requirements of various applications. In multi-hop wireless networks, cooperative communication is an effective and successful way to improve performance [ 20 , 41 , 42 ].…”

“…As a matter of fact, when a vehicle wishes to send its data packets, it competes for channel access without guaranteeing successful packet transmissions. They also have some limitations that cause broadcast storm problems, severe packet collisions, large average coverage delay, and diminished reachability [ 20 , 22 ]. In contrast, the main idea of contention-free schemes is to eliminate unnecessary collisions and avoid predicaments via the periodic exchange of control messages to maintain the scheduled table and network time in synchronization [ 17 ].…”

“…It is undeniable that delay is one of the most crucial metrics to evaluate the QoS of a network [ 22 , 23 ]. In principle, the delay for successfully transmitting a data packet from one vehicle to another consists of various elements, including processing delay, queuing delay, local delay, and access delay over a link [ 23 ].…”

In vehicular ad hoc networks (VANETs), efficient data dissemination to a specified number of vehicles with minimum collisions and limited access delay is critical for accident prevention in road safety. However, packet collisions have a significant impact on access delay, and they may lead to unanticipated link failure when a range of diversified collisions are combined due to complex traffic conditions and rapid changes in network topology. In this paper, we propose a distributed contention-free cooperative medium access control (CFC-MAC) protocol to reduce heterogenous collisions and unintended access delay in stochastic traffic scenarios. Firstly, we develop a cooperative communication system model and cooperative forwarding mechanism to explore the optimum road path between the source and destination by identifying the potential cooperative vehicles. Secondly, we propose a vectorized trajectory estimation mechanism to suppress merging collisions by identifying the relative velocity of vehicles with different speeds in a specific time interval. Based on the case study, typical heterogeneous collisions and aggregated heterogeneous collisions at dissociated positions and associated positions are investigated. In both cases, we propose the corresponding collision-resolving mechanisms by methodically recapturing the colliding time slot or acquiring the available free time slots after identifying the access vehicles and comparing the received signal strengths. Performance analysis for collision probability and access delay is conducted. Finally, the simulation results show that the proposed protocol can achieve deterministic access delay and a minimal collision rate, substantially outperforming the existing solutions.

The Internet of Things (IoT) is a network of physical objects or “things” implanted with electronics, software, sensors, and connectivity to allow them to exchange data with servers, centralized systems, and other connected devices using several communication systems. IoT data is assembled from various sensors, nodes, and collectors and sent to the cloud. It is the most reliable framework for improving the quality and comfort of human life. It has made a substantial contribution to a wide range of applications. By 2020, it is expected that 31 billion IoT devices will be deployed worldwide. The rapid growth of smart devices and their reliance on wireless mechanics for data transfer have increased their vulnerability to cyberattacks. As a result, studying IoT security dangers and viable countermeasures can aid academics in discovering acceptable solutions to various cybercrime investigation challenges. In this study, various security vulnerabilities at each layer are also examined in‐depth and corrective options for smart city applications and Industry 4.0. A comparison analysis of IoT/IIoT wireless communication features and security challenges in IoT systems is also part of this study. The relevance of IoT forensics in cybercrime investigation in many areas such as smart homes, smart cities, automated cars, and healthcare is also discussed in this study. This article presents IoT security concerns and open issues, laying the groundwork for future research.
