For Wireless Sensor Networks (WSNs), although many localization techniques have been proposed, development of effective localization techniques for sensor nodes, which do not require any hardware or computational burdens on them, continues to be a challenging task. Motivated by this need, this paper proposes a new location discovery scheme in WSNs so called Sectoral Sweeper based Location Estimation...
Advancements in directional antennas or adaptive antenna arrays (AAA) provide potential benefits in solving various problems in wireless sensor network (WSN). Our earlier studies have investigated feasibility of applying smart antennas for task dissemination and localization purposes [4], [6]. Network connectivity or connectivity probability is also an important issue for smart antenna capable WSN...
We introduce a novel sensor node management and location estimation method referred as sectoral sweeper (SS) scheme that uses an adaptive antenna array (AAA) at a central node in wireless sensor networks (WSNs). With the SS scheme, the central node can activate or deactivate the nodes in a desired region which is specified by beam direction and beam width of the transmit beam and also by minimum and...
