Overall outage event of self-sustaining low-power cooperative relaying networks
This paper investigates the implementation of the household low-power
energy harvesting (LoPEH) wireless sensor networks (WSN) over
log-normal fading channels. The relays are battery-operated and the
stochastic harvested energy flow to the…
