<p style="margin: 0in 0in 10pt;"><span style="-ms-layout-grid-mode: line;"><span style="font-family: Times New Roman; font-size: small;">The traditional multi-hop positioning algorithm is easily affected by the network anisotropy, thus resulting in unstable positioning performance. The wireless sensor network multi-hop positioning algorithm based on continuous regression is put forwarded in the paper to address this problem. By utilizing the continuous regression model, the mapping relationship between the hop count and Euclidean distance is constructed so as to transform the positioning process model into regression prediction. Theoretical analysis and simulation results show that the improved algorithm improves the positioning accuracy, and avoids the influence of the network topology anisotropy on the performance of the algorithm. The algorithm requires little expenditure and few parameters so it can be adapted to wireless sensor networks with irregular nodes distribution, and can be of great engineering application value.</span></span></p>

Wireless sensor network positioning technology has become one of research hotspots today. This paper mainly studies the TOA positioning algorithm based on WSN. The number of beacon nodes used to locate unknown nodes is discussed. There are four situations for the number of beacon nodes n=3, 4, 5, 7 that are analyzed via simulation, also locating error. We get the optimum value of n via simulations.

High speed stackers are the critical equipments for automated storage/retrieval systems to improve efficiency and throughput. And the positioning technique is the key to speed regulating. The low cost and easy installation indoor positioning of wireless sensor network is applied in this situation. A novel quadrilateral projection algorithm taken advantage of the linear moving of stackers is proposed to reduce the complexity of the algorithm and improve ranging accuracy of positioning.
