Wireless location has become one of the important technologies of wireless sensor network application. Due to the underground wireless location affected by various factors, the positioning system cannot meet the actual demand. In this paper, Time Difference of Arrival (TDOA) and Received Signal Strength Indicator (RSSI) location technologies have been investigated, then various impact factors on the TDOA and RSSI location systems have been discussed, multipath channel, different shapes of the roadway on the propagation loss. In order to reduce the error, estimation error has been correlated and compensated. Simulations show that the proposed system consistently outperforms other existing localization methods and can achieve higher accuracy.
