Collaborative beamforming has been recently introduced in the context of wireless sensor networks (WSNs) to increase the transmission range of individual sensor nodes. In this pap...
Abstract— This paper proposes a simple yet efficient localization algorithm for GPS-free sensor nodes in wireless sensor networks (WSN). Our approach is hybrid in the sense that...
—In wireless sensor networks, sensor nodes are expected to gather specific information about the environment and send it to the user. The data dissemination usually involves many...
