“…The performance optimization of a single objective protocol does not consider varying aspects of the vehicular network. However, in a practical real environment, a trade-off may exist between multiple metrics, such as delay and throughput [114], fairness and spectrum spatial reuse [115], energy and throughput [116], to name a few. Hence, there is a need to design CVN protocols, which considers these trade-offs to fulfill the requirements of a practical real environment.…”

With the remarkable progress of cooperative communication technology in recent years, its transformation to vehicular networking is gaining momentum. Such a transformation has brought a new research challenge in facing the realization of cooperative vehicular networking (CVN). This paper presents a comprehensive survey of recent advances in the field of CVN. We cover important aspects of CVN research, including physical, medium access control, and routing protocols, as well as link scheduling and security. We also classify these research efforts in a taxonomy of cooperative vehicular networks. A set of key requirements for realizing the vision of cooperative vehicular networks is then identified and discussed. We also discuss open research challenges in enabling CVN. Lastly, the paper concludes by highlighting key points of research and future directions in the domain of CVN.

“…However, it also increases the interference which degrades the chances of transmission success. Hence, the CST imposes a delicate tradeoff between the transmission quality, measured by the probability of transmission success, and the spatial frequency reuse (SFR), quantified by the spatial density of concurrent transmitters [11]. This performance tradeoff has been well recognized in literature and attempts have been made to maximize the spatial density of successful transmissions by tuning the CST [12].…”

Mission critical data dissemination in massive Internet of things (IoT) networks imposes constraints on the message transfer delay between devices. Due to low power and communication range of IoT devices, data is foreseen to be relayed over multiple device-to-device (D2D) links before reaching the destination. The coexistence of a massive number of IoT devices poses a challenge in maximizing the successful transmission capacity of the overall network alongside reducing the multihop transmission delay in order to support mission critical applications. There is a delicate interplay between the carrier sensing threshold of the contention based medium access protocol and the choice of packet forwarding strategy selected at each hop by the devices. The fundamental problem in optimizing the performance of such networks is to balance the tradeoff between conflicting performance objectives such as the spatial frequency reuse, transmission quality, and packet progress towards the destination. In this paper, we use a stochastic geometry approach to quantify the performance of multi-hop massive IoT networks in terms of the spatial frequency reuse and the transmission quality under different packet forwarding schemes. We also develop a comprehensive performance metric that can be used to optimize the system to achieve the best performance. The results can be used to select the best forwarding scheme and tune the carrier sensing threshold to optimize the performance of the network according to the delay constraints and transmission quality requirements.

“…To overcome this problem they developed Carrier Sense based Medium Access (CSMA) protocols to attain high spatial reuse by proper transmissions coordination among the neighbouring nodes to reduce congestions. Increase in spatial reuse for wide range of node densities is achieved by QT-CSMA [22] than O-CSMA. The dominated sets of spatial fairness-reuse pair under QT/O-CSMA shows the relationship between joint spatial reuse and fairness performance to understand the interactions between the nodes.…”

The present wireless routing protocols does not increase the end-to-end throughput by reducing the number of hops to deliver a single packet from a source to a destination node. To maintain the proper link among the nodes in multihop wireless ad-hoc networks, the medium access control (MAC) protocol plays a vital role. The spatial reuse and throughput of a multihop network is greatly affected in assessing the level of interference, channel sharing was not expeditiously utilized by the prevailing methodology of the IEEE 802.11.Routing protocols are generally depends on transmission cost, minimizing routing metrics. But they fail to give assurance for increasing end-to-end throughput. The existing protocols don't take spatial reusability of the remote correspondence media into account. This paper overviews numerous techniques to upgrade the effective channel use by enhancing the spatial reuse.
