In wireless sensor networks (WSNs) duty cycling has been an imperative choice to reduce idle listening but it introduces sleep delay Thus, the conventional WSN medium access control protocols are bound by the energy-latency tradeoff. To break through the tradeoff, we propose a radio wave sensor called radio frequency (RF) wakeup sensor that is dedicated to sense the presence of a RF signal. The distinctive...
In wireless sensor networks (WSNs) duty cycling has been an imperative choice to reduce idle listening but it introduces sleep delay. Thus, the conventional WSN MAC protocols are bound by the energy-latency tradeoff. To break through the tradeoff, we propose a radio wave sensor called RF watchdog that is dedicated to sense the presence of a RF signal. The distinctive feature of our design is that...
Conventional MAC protocols for wireless sensor networks have adopted duty cycling to reduce idle listening, but duty cycling leads to energy-latency tradeoff, which is one of the major challenges for designing energy efficient and high performance MAC protocols for wireless sensor networks. To break through the energy-latency tradeoff caused by duty cycling in the existing wireless sensor network,...
