摘要：
In order to solve the problems of high-speed mobility, energy limitation and communication delay of nodes in networked navigation systems(NNSs), a cross layer medium access control (MAC) protocol based on graded nodes(GN-MAC) is designed by which a routing algorithm combining cross routing tree construction based on mobile sink and chain clustering(CRTCC) is mixed. GN-MAC adopts the way of media access based on competition, defines the packet format according to the characteristics of CRTCC, and completes the virtual clustering with multi-level nodes. At the same time, an improved node mobility detection algorithm is designed, the optimal inter cluster handoff decision is made, and the priority based competition and multi-channel communication are proposed. Finally, the simulation shows that the delay and energy consumption are effectively controlled in the case of high-speed mobile nodes and multiple mobile nodes. © 2022, Editorial Office of Systems Engineering and Electronics.
