A Localization Algorithm Based on Particle Swarm Optimization and Quasi-Newton Algorithm for Wireless Sensor Networks
نویسنده
چکیده
The position information is becoming more and more important for application in WSNs. So aiming at the location problem, the paper proposes a localization algorithm based on PSO (particle swarm optimization) and Quasi-Newton algorithm, which use PSO to get a satisfying value and then use it as the initial value of Quasi-Newton algorithm to iterate. The simulation experiments are carried out. The results show that the proposed algorithm not only fastens the localization speed and has improved the localization precision effectively.
