Energy efficiency is a major concern in the design of Wireless Sensor Networks (WSNs) and their communication protocols. As the radio transceiver typically accounts for a major por...
—WPAN technologies such as IEEE 802.15.4 have been introduced to allow for energy-efficient communication of control and sensor data. In certain application areas, it is benefici...
—Location information should be verifiable in order to support new computing and information services. In this paper, we adapt the classical challenge-response method for authen...
When the range of single-hop wireless communication is limited by distance or harsh radio propagation conditions, relays can be used to extend the communication range through mult...
