Abstract

The localization and tracking of mobile nodes is a study focus in the application of wireless sensor networks. This paper makes a research on localization of mobile nodes in wireless sensor network and proposes a kind of mobile nodes localization algorithm based on ant colony algorithm. The novel algorithm uses distribution probability and transition probability of ant colony algorithm from one node to the other to calculate the weight coefficients of samples, and then determine the possible locations of mobile nodes. The simulation results show that using probability selection strategy to estimate the locations of nodes has lower computational complexity, higher positioning accuracy and stronger robustness.
