Abstract:In many applications of wireless sensor network (WSN), the location of sensors is a necessity to evaluate the sensed data and it is not energy and cost efficient to equip all sensors with global positioning systems. In WSN localization, some sensors (called anchors) are aware of their location. Then, the distance measurements between sensors and anchors are used to localize the whole network. WSN localization is a non-convex optimization, however, relaxation techniques such as semi-definite programming (SDP) a… Show more
