Research on DV-HOP Algorithm for Wireless Sensor Networks.

The DV-Hop algorithm is a typical location algorithm in wireless sensor networks. This paper gives Mesh-like distribution nodes and randomly distributed nodes in the square area, and analyzes the algorithm several important parameters, including the number of anchor nodes, communication radius and the total number of nodes, of which parameters impact on the positioning error, and gives the simulation results and analysis. Through the simulation results, the optimum value of the parameter in DV-Hop algorithm have been obtained. Theoretical analysis and simulation results demonstrate that parameters of the optimized algorithm effectively reduce the node positioning error.
