REN Zhong-yuan, CHEN Jia-pin, LI Zhen-bo, et al. Research on a RF localization algorithm based on wireless sensor networks[J]. 2012, 31(7): 52-54. DOI: 10.13873/j.1000-97872012.07.019.
A novel estimation method based on radio frequency(RF) localization is presented.The received signal strength(RSS) from unknown node at the anchor nodes is measured
and the RSS information is transformed into distance estimations.By using these estimations
a probability distribution model of the unknown node is got and location when the probability is maximum is found as the destination.Using Matlab as simulation tool
the result shows that compared with previous methods
