Adaptive Distance Estimation Based on RSSI in 802 . 15 . 4 Network

  title={Adaptive Distance Estimation Based on RSSI in 802 . 15 . 4 Network},
  author={Miroslav Botta and Milan Simek},
This paper deals with the distance estimation issue in 802.15.4 wireless sensor networks. On a basis of signal strength of received frames a distance between two sensor nodes is estimated. Estimation is done by using the log-normal shadowing radio propagation model (LNSM). Basic problems of signal strength based systems are variation of RSSI parameter and correct calibration of coefficients for the LNSM model. For distance estimation in wireless networks, static and dynamic methods of… CONTINUE READING
