Abstract:

Aiming at the problems of node energy limitation and network communication delay in networked navigation systems, a routing algorithm combining cross routing tree construction based on mobile sink and chain clustering (CRTCC) is designed. CRTCC plans the path of the mobile sink, creates the cross region centered on the mobile sink and constructs the cross routing tree with the nodes in the cross region as the objects. At the same time, for the nodes outside the cross region, according to the characteristics of the ant colony algorithm, the angle between the candidate cluster heads is introduced, the cluster head selection strategy is reformulated, the chain cluster structure is constructed, and the data transmission path planning is completed. Finally, an example simulation is given to verify the effectiveness of the algorithm.

Key words: networked navigation system, mobile sink, routing protocol, cross routing tree, chain clustering
