Many emerging applications in both wired and wireless networks need support of secure group communications. There have been many secure group communication schemes in the setting ...
This paper presents a proof-of-concept wireless sensor network for detecting and tracking friendly objects and detecting and localizing foreign objects. The network incorporates a...
– Integration of beamforming to sensors is very beneficial for a reduction of transmission power consumption and for improvement of the overall system performance. Unfortunately,...
— A fundamental goal of a wireless sensor network (WSN) is to collect and deliver data to external applications. Due to the strong constraints of these networks, routing algorith...
