A Research on the Localization Technology of Wireless Sensor Networks Employing TI's CC2530 Instrument

Many applications of wireless sensor networks depend on the location information of sensor nodes and how to obtain the localization has become the focus of research activities in WSN. In order to solve the problem the log-normal shadow model and the trilateration method is used to estimate location of a sensor node in the paper. Many Experiments have been done to reduce the distance error and the experiment results show that the method is a better way for node position.
