In this paper, we propose a practical implementation of a location identification approach. In this approach, only the basic assumptions that are realistic in most types of Ad Hoc/Sensor networks are required, which means that this system is implementable in most kinds of Ad Hoc/Sensor networks. By introducing the idea of cell-based location identification method into the system, some drawbacks to the TDOA (Time Difference of Arrival) system are resolved. More importantly, by employing the new theory, the location estimation accuracy of the proposed system is improved without costing extra resources. Finally, simulations show that the proposed Hybrid TDOA (HTDOA) location estimation system performs better in different environments compared with the current TDOA method.
