Improving Energy Efficiency of Mobile WSN Using Reconfigurable Directional Antennas

Reconfigurable directional antennas (RDA) bring new opportunities to reduce data collision in wireless sensor networks (WSN). In this letter, a new reconfigurable directional antenna-based receiver-Initiated cycled receiver (RDA-RICER) medium access …

WSN-based solutions for security and surveillance

Wireless sensor networks (WSNs) are composed of autonomous sensor nodes that cooperate among themselves to monitor scenarios in environmental, industrial, civilian and military applications. The wide applicability of such systems stimulates the …
