• Trilateration technique measures the _______to all anchors and Triangulation measures ________to all anchors,
• Node gather enough anchor points and measurements, they compute their own locations. Once they have localized, they also declare themselves as an anchors. In this way, sensor nodes without enough anchors get a chance to localize. This approach is called as ____________ localization.
