The Research of Cooperative Location Model in Wireless Sensor Network based on Four-cross Array

摘要：

Four-cross array location is widely used in sensor network, but the location accuracy of four-cross array is affected by time-delay error, array size error and so on. This paper derives the relationship of errors between array size with location based on TDOA, and proposes a model which is cooperative location in wireless sensor network based on fourcross array. The simulation results show that the model has better location accuracy relative to the single four-cross array.
