Spatial Models for Human Motion-Induced Signal Strength Variance on Static Links

  title={Spatial Models for Human Motion-Induced Signal Strength Variance on Static Links},
  author={Neal Patwari and Joey Wilson},
  journal={IEEE Transactions on Information Forensics and Security},
A wireless network can use the variance of measured received signal strength (RSS) on the links in a network to infer the locations of people or objects moving in the network deployment area. This paper provides a statistical model for the RSS variance as a function of a person's position with respect to the transmitter (TX) and receiver (RX) locations. We show that the ensemble mean of the RSS variance has an approximately linear relationship with the expected value of total affected power… CONTINUE READING
