The optimization research of node localization algorithm based on wireless sensor network

Wireless Sensor Network as an important technology of Internet of things´ development, is more and more widely used in various research fields. This paper mainly researches the part of localization application based on wireless sensor network, focuses on DV-Hop localization algorithm, and gives its algorithm simulation and analysis of the simulation results. Also this paper improves the algorithm from the defect problems of the original algorithm to get this improved algorithm and the simulation is in comparison with the original algorithm. The simulation results shows that the localization accuracy of the improved DV-Hop algorithm is better, less number of anchor nodes, improving the positioning performance significantly.
