One Kind of Distributed Localization Method for Sensor Networks
Authors: ,
Abstract: In order to solve the problem of localization of the acoustic source by using sensor networks, one kind of distributed location scheme was proposed, here. Firstly, the sensor networks reference node and network topologies were defined. Then, the pulse-coupled clock synchronization algorithm was introduced to synchronize all node clocks, and besides that, the time difference of arrival of the source sound signals to all the nodes was measured on the basis of the clock synchronization. Finally, the position of the sound source was located by sensor networks equipped with distributed localization algorithm. In case of completeness, the four different forms of configuration, classical wedge, quad, symmetric wedge and circle, were taken for examples to verify the suggested idea. And each kind of network distribution topological configuration form was computed repeatedly for 1000 times, under the linear iterative algorithm.
