“…To coordinate the access of the control channel, we adopt a self‐organized time division multiple access (STDMA) setup, as illustrated in Figure . It has been demonstrated that STDMA can achieve faster schedule reconfiguration than TDMA and more predictable communication delay in comparison with IEEE 802.11p, especially in the presence of vehicle crowding and broadcast storms . Each vehicle periodically broadcasts CAMs, and the time interval between CAM generation should be no larger than 100 ms, as suggested by the ETSI standard .…”

Summary The rapidly growing demand for accident‐free driving in intelligent transportation makes reliable broadcast a critical factor for vehicular ad hoc networks. Existing solutions always try to improve the broadcast reliability by retransmitting lost packets. However, the excessive retransmissions can easily cause unpredictable time delay and even broadcast storms, rendering the reliable broadcast problem unsolved. In this paper, a novel reliable broadcast scheme is proposed by exploring the advantages of lost data piggybacking. Our scheme allows all the vehicles to piggyback some received packets cooperatively to help other vehicles to recover the lost packets. We formulate the cooperative piggybacking problem as a cooperative offloading game and present a decentralized solution to compute the optimal data piggybacking solutions based on only partial network information. A reward‐penalty scheme is designed for the offloading process to impel all the vehicles' decisions that converge to the Nash equilibrium, which is proved to be the global optimal solution to the decentralized offloading scheme. Simulation results show that the proposed cooperative offloading scheme can achieve much higher broadcast reliability and lower propagation delay, in comparison with existing solutions. In a small vehicle network, all lost cooperative awareness messages can be successfully recovered within 25 ms after the initial broadcast by using the data traces generated by GEMV2.

“…The overall structure is considered in the context of a timevarying environment where UAV swarm missions are classified depending on their requirements on bandwidth, latency, throughput, and packet loss. Then, the controller train a DNN that, based on data analysis and mission requirements, select the optimal medium access control mode among CSMA/CA [82], DTDMA [83], ESTDMA protocol which is used for multi-hop communication with slight modification of STDMA [84]. Simulation results illustrated how the controller is able to provide efficient decisions and to release them to the physical entity in a very timely way.…”
