Research on Random Access of Air-sea Ad-hoc Network
Addressing the air-sea information collaboration and sharing requirements for UAVs in distant maritime operations,a dynamic priority-based transmission protocol is proposed for random access.Firstly,this protocol is designed to ensure stable telem-etry and remote control information transmission within the cluster measurement and control communication ad-hoc network through efficient cluster networking signaling.Secondly,combines an improved TDMA network time-slot structure for fast node en-rollment and dynamic time slot allocation.Finally,an OPNET network simulation is used to analyze the random access,low latency,high throughput,and low end-to-end latency performance of the designed cluster air-sea self-organizing network system.The results indicate that the network establishment time under this signaling scheme requires only 2-3 flight control cycles.In a scenario with 32 nodes,the average delay for nodes to complete random Aloha network access is less than 0.6 seconds.Additionally,the improved TDMA protocol reduces end-to-end latency by 1/3 compared to traditional TDMA protocols.
