Summary: This paper proposes a decentralized cooperative broadcasting protocol for Vehicle-to-Vehicle (V2V) communication, which allows vehicles to piggyback received messages in their routine broadcasts to help others recover lost traffic information. By introducing a bitmap data structure to record the receiving status of each vehicle, the protocol enables efficient detection of lost messages, estimation of wireless link quality, and achieves high reliability in message delivery.

Summary: Vehicular ad-hoc networks (VANETs) pose challenges for robust and scalable communication. Existing clustering techniques generate excessive clusters, leading to resource consumption and increased communication overhead. To address this, a novel clustering algorithm based on the Harris Hawks Optimization algorithm (HHOCNET) is proposed. Simulations show that HHOCNET outperforms state-of-the-art schemes in optimizing the multi-objective clustering problem in VANETs.

Summary: In this paper, a three-dimensional universal cooperative localizer (3D UCL) is proposed for vehicular ad-hoc networks (VANETs), and a 3D geographical information enhanced UCL (3D GIE-UCL) is developed by combining 3D UCL with a NLOS identification mechanism assisted by geographical information. Both 3D UCL and 3D GIE-UCL show significant improvement in positioning performance after the application of acceleration techniques.

Summary: In this paper, a distributed contention-free cooperative medium access control (CFC-MAC) protocol is proposed to reduce heterogenous collisions and unintended access delay in stochastic traffic scenarios. A cooperative communication system model, cooperative forwarding mechanism, and vectorized trajectory estimation mechanism are developed to explore the optimum road path between the source and destination and suppress merging collisions. Performance analysis and simulation results show that the proposed protocol outperforms existing solutions in terms of access delay and collision rate.
