In this paper, a clustering based resource management scheme for latency and sum rate optimization in V2X networks is proposed to identify distinguished demands for different kinds of vehicular links, namely cellular-vehicle-to-vehicle (C-V2V) links and cellular-vehicle-to-infrastructure (C-V2I) links, and to improve the performance of cellular user in terms of sum rate, latency and throughput for C-V2I links while guaranteeing reliability for every C-V2V connection. To address the fast channel changes due to high mobility, we present a clustering based resource management model to achieve band sharing and efficient power management that depends on large scale fading. Besides, we have also considered the resource management problem of cellular V2X and VANETs users to reduce data transmission impacts. Firstly, the total average sum rate of each C-V2I links is used as an optimization goal to increase the throughput and to reduce latency of the entire C-V2I link. Secondly, cluster based optimum algorithms are proposed which give the optimum resource management. Simulation results reveal that the proposed scheme outperforms the existing scheme.

Legacy TCP/IP protocol has gradually revealed many deficiencies, such as poor mobility and scalability. The distribution of information based on the content has a possible number of practical applications in the vehicular environment, such as congestion detection, collision avoidance, emergency announcements, parking notifications, and advertising. In this study, we have presented a technique for the distribution of information based on the content in a hybrid vehicle-to- everything (V2X) environment. The COC-V2X technique relies on contents that each vehicle having by communicating with each other, and has the potential to solve some of the problems that present in IP-based VANETs. It can also gain edge of both the cellular eNodeB if there exists the decentralized vehicle-to-vehicle communication technologies. We evaluate the performance of the proposed approach via realistic VANETs traces based scenarios. The preliminary conclusions illustrate that our proposed novel approach is superior to current legacy TCP/IP in terms of message delivery, low latency, and low overhead.
