“…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.…”

“…DT-MAC 20 introduces a novel frame structure to effectively accommodate dynamic event traffic by varying the number of slots and their lengths according to the QoS requirements of different services. The shortest job first (SJF) and knapsack algorithms in BS-MAC 21 and BEST-MAC, 22 respectively, allow sensor nodes to transmit their data as a whole in order to avoid the energy consumption due to frequent radio switching.…”

Summary Recent advances in microelectronics have encouraged the implementation of a wireless sensor network (WSN) in intelligent monitoring systems (IMSs). The IMS for time‐critical applications requires timely and reliable data delivery without sacrificing the energy efficiency of the network. This paper proposes FPS‐MAC, a fuzzy priority scheduling‐based medium access control protocol, designed for event critical traffic in hierarchical WSN. The FPS‐MAC allows time‐critical event traffic to opportunistically steal the data slots allocated for periodic data traffic in event‐based situations. Additionally, a fuzzy logic‐based slot scheduling mechanism is introduced to provide guaranteed and timely medium access to emergency traffic load and ensures the quality‐of‐service (QoS) requirements of IMSs. Both analytical and simulation results for data throughput, energy consumption, and transmission delay of FPS‐MAC, TLHA, E‐BMA, and BMA‐RR have been analyzed to demonstrate the superiority of the proposed FPS‐MAC protocol.

“…Lei et al [56] proposed a dynamicTDMA‐based MAC protocol called DT‐MAC to facilitate QoS assurance in fullyconnected ad hoc networks. The DT‐MAC protocol comprises aflexible frame structure in which the length of the TDMA frame and the number ofslots in each frame is adjusted dynamically according to the QoS requirements ofsensor nodes as shown in Fig.…”
