A novel approach for duty-cycled wake-up radios (WuRs) is proposed with focus on environmental monitoring applications involving wireless sensing devices left unattended in harsh conditions. In this scenario, a higher data latency (on the order of seconds or minutes) is potentially acceptable if ...
It also permits the ordinary (member) nodes in a cluster to turn off their radios whenever they enter inactive TDMA slots. However, LEACH does not consider broadcast messages, and the member nodes scheduling is established as a sequence of Time Division Multiple Access (TDMA) without any common...
We discuss practical implementation issues of PCOs for these radios and show that such systems can be created with extremely low cost and low complexity integrated components with acceptable synchronization performance. Finally, we demonstrate simple wireless synchronization of PCOs, and show that ...
Sensor nodes in duty-cycle networks schedule the transmission and reception of data during active periods, and switch the radios off completely during sleep periods to conserve energy. Huang et al. [1] and Ahmad et al. [2] provide comprehensive reviews of duty-cycle MAC protocols for WSNs. ...
