Research and Simulation of Node Localization in WSN Based on Quantum Particle Swarm Optimization

There're so many kinds of localization algorithms with a big localization error. And how to reduce this error is really a very important problem. This paper studies four distributed localization algorithms in WSN, and introduces a pretty popular optimization algorithm named quantum particle swarm optimization algorithm into it. In the end, this paper does some simulations with mat lab. And it proves that the QPSO algorithm works well in node localization algorithm.
