    • A distributed positioning algorithm for cooperative active and passive sensors 

      Gholami, M.R.; Gezici, Sinan; Rydström, M.; Ström, E.G. (IEEE, 2010)
      The problem of positioning a target node is studied for wireless sensor networks with cooperative active and passive sensors. Two-way time-of-arrival and time-difference-of-arrival measurements made by both active and ...
    • Hybrid TW-TOA/TDOA positioning algorithms for cooperative wireless networks 

      Gholami, M.R.; Gezici, Sinan; Ström, E.G.; Rydström, M. (IEEE, 2011)
      The problem of positioning an unknown target is studied for a cooperative wireless sensor network using hybrid two-way time-of-arrival and time-difference-of-arrival measurements. A maximum likelihood estimator (MLE) can ...
    • Positioning algorithms for cooperative networks in the presence of an unknown turn-around time 

      Gholami, M.R.; Gezici, Sinan; Ström, E.G.; Rydström, M. (IEEE, 2011)
      This paper addresses the problem of single node positioning in cooperative network using hybrid two-way time-of-arrival and time-difference-of-arrival where, the turn-around time at the target node is unknown. Considering ...
    • Static positioning using UWB range measurements 

      Gholami, M.R.; Ström, E.G.; Sottile F.; Dardari, D.; Conti, A.; Gezici, Sinan; Rydström, M.; Spirito, M.A. (IEEE, 2010)
      The performance of several existing and partly new algorithms for positioning of sensor node based on distance estimate is compared when the distance estimates are obtained from a measurement campaign. The distance estimates ...
