Abstract:In order to solve the shortcomings of the current mobile wireless sensor network node localization scheme, such as more complex sensing process, lower localization accuracy, and more difficulty in adapting to the actual scene where the node topology changes frequently, a mobile wireless sensor network node localization algorithm based on virus body projection mechanism is proposed. Firstly, in view of the shortcomings of the current direct and indirect sequencing schemes in anti-noise ability, a multi-point positioning scheme is designed, and the joint positioning of multiple anchor nodes is introduced. In the positioning process, RSSI error is reduced by iteration, which effectively solves the circular distribution phenomenon in the positioning process. Subsequently, aiming at the fast speed of topological drift and the random distribution of coordinates in mobile wireless sensor networks, anchor nodes are regarded as virus bodies, mobile wireless sensor network nodes are regarded as sub-virus bodies, and for the random topological rules between virus bodies and sub-virus bodies, the virus body projection mechanism is introduced, and the distance location scheme is designed by iteration. The topological drift relationship between the location node and the node to be located in the positioning process of mobile wireless sensor network can improve the network's perception of the positioning process. Finally, the weight adjustment mechanism is introduced to eliminate the positioning coordinate errors, further improve the positioning accuracy of the network and stabilize the perception performance, strengthen the perception and monitoring of the topology between nodes in the mobile state, and reduce the impact of network jitter on the positioning process. The simulation results show that the proposed algorithm algorithm has higher convergence speed and lower positioning error compared with OECO algorithm, as well as AN-DV-Hop algorithm.
