The node localization algorithms based on distance measurement are mainly studied in this paper.A stepwise weighted positioning algorithm based on distance measurement is designed on the basis of analyzing several typical positioning algorithms,static nodes positioning under natural environment is achieved. On this basis,with STMS32 selected as a core chip in the paper,the basic system circuit and peripheral interface circuit of node device is designed,and then using the development software BeeKit and CodeWarrior for node software design,localization algorithm is testedthrough experiment.After analyzing the results,the algorithm is mostly influenced by the RSSI ranging error,the coarse positioning of node can be achieved. |
