| Abstract: | In order to solve the problem that wireless sensor network positioning accuracy is sensitive to the environmental impact,we researched on the localization algorithm to improve positioning accuracy through the experiment on a wireless sensor network.The system use CC2430 wireless module as node transceiver,build a wireless sensor network platform based on ZigBee wireless sensor network protocol for positioning system development and the improved algorithm.Because of the complexity of the wireless signal strength error,we improve the localization algorithm one by one stage improvement through the experimental error analysis.The test results in wireless sensor network platform show that precision obviously improved and the improvement wireless sensor network localization algorithm is worthy of using and achieved the anticipated effect. |
