Research on Time Slot Allocation Technology of Air-Sea Ad-Hoc Network

Air-sea ad-hoc network is widely used in various maritime activities due to its advantages of strong flexibility and low cost. Time Division Multiple Access (TDMA) is suitable for the design of network MAC layer protocol, so it is of great significance to design efficient and reasonable time slot allocation algorithm to improve network performance. To solve the problem of time slot waste of traditional dynamic TDMA protocol, this paper proposes a dynamic TDMA protocol with time slot reclamation (TSR-DTDMA). The cluster head performs message listening and time slot reclamation decision, reclaims the long-term idle time slots, allocates them to nodes with higher traffic rates, and informs the entire network through the signaling frame. The simulation results show that the TSR-DTDMA protocol can optimize the network throughput, average delay, packet loss rate and improve time slot utilization as well as network quality of service (QoS) effectively.
