To optimize the topology of self-organizing wireless sensor networks and improve the networks" overall perform- ance, an algorithm for generating wireless sensor networks based on Delaunary is proposed according to the node tri- angulation characteristics of wireless sensor networks. Meanwhile, the working mechanism and the rotation mecha- nism of information nodes and energy nodes in the network system is given in detail. The simulation results show that the Delaunay topology structure generated in this study using the proposed algorithm is suitable for node com- munication and data acquisition in a complex environment. And compared with the structures of star network, mesh network and mixed network, the Delannary network topology structure has the shortest length of the network topolo- gy, and the longest lifetime at the same nodes within the fixed region.
