Dynamic Beacon Mobility Scheduling for Sensor Localization

Mobile-Assisted Anchor Outlier Detection for Localization in Wireless Sensor Networks

“…Several methods can be used to compute the location of an unknown node such as triangulation [5], multilateration [8], and trilateration [21]. The choice of which methods to use depends on ranging technique used in step (1).…”

“…In these applications, it is necessary for the nodes to know their own physical locations. In addition, location information provides essential network operations such as routing protocols, clustering, data centric storage and geographic key distribution [1][2][3].…”

Outlier Detection Techniques for Localization in Wireless Sensor Networks: A Survey

“…In environmental monitoring applications such as water quality monitoring, bush fire surveillance, and precision agriculture, the measurement data are meaningless without knowing the location from where the data are obtained [18]. In addition, location estimation plays an important role in some network functionalities such as geographic routing and data centric storage [19].…”

“…However, this solution is impractical since GPS are expensive and high energy consuming [3,18,19]. In recent years, a number of localization algorithms have been proposed to reduce or remove the dependence on GPS in WSNs [9][10][11][21][22][23][24][25].…”
