Sensor location information is a prerequisite to the utility of most sensor networks. In this paper we present a robust and low-complexity algorithm to self-localize and orient se...
— Key management has long been a challenging problem in wireless Distributed Sensor Networks (DSNs) due to their high security requirements and strict resource constraints. Recen...
Recently, a semidefinite programming (SDP) relaxation approach has been proposed to solve the sensor network localization problem. Although it achieves high accuracy in estimating ...
Abstract--Sensor networks can benefit greatly from locationawareness, since it allows information gathered by the sensors to be tied to their physical locations. Ultra-wide bandwid...
The wireless sensor network based localization system—Cicada is designed to support the locationawareness in indoor environment. The system is based on TDOA (time difference of ...
