A Grid-Based Linear Least Squares Self-Localization Algorithm in Wireless Sensor Network

International Journal of Distributed Sensor Networks, 2015
Self-localization is one of the key technologies in the wireless sensor networks (WSN). Some traditional self-localization algorithms can provide a reasonable positioning accuracy only in a uniform and dense network, while for a nonuniform network the ...

Linear approaches to resilient aggregation in sensor networks

Journal of Mathematical Cryptology, 2015
A sensor network is a network comprised of many small, wireless, resource-limited nodes that sense data about their environment and report readings to a base station. One technique to conserve power in a sensor network is to aggregate sensor readings hop-
