A self-calibrated centroid localization algorithm is presented for wireless sensor networks based on IEEE 802.15.4 radio standard. Beside common issues in ranging accuracy using either received signal strength (RSSI) or link quality (LQI), it is challenging to cope with the fast changing environments. Although good accuracy has been achieved with methods such as Weighted Maximum Likelihood Estimation...
Precise location information is crucial for many wireless sensor network (WSN) applications. Location aware WSN sensor nodes can normally exchange information by knowing each other coordinates. In this paper we study and evaluate an algorithm based on parametric loop division (PLD), where anchor nodes form a triangle which uses coordinate of anchor nodes for three-dimensional (3D) nodes localization...
