Tells about the difficulties of the trek: snow, walking on narrow mountain paths, unreliable porters & guides.
In cognitive wireless networks, the spectrum sensing outcomes are often unreliable due to the path loss, channel fading, noise uncertainty, shadowing, etc.
In addition, the unstable acoustic channel condition and the dynamic network topology of UWSNs make the conventional single path forwarding protocols very unreliable.
However, the local spectrum sensing is often unreliable due to the impact of path loss, channel fading, shadowing, noise uncertainty, etc.
Thus, we can simply use Q Δ to probe whether or not the path d cp to be with unreliable transmission condition (high loss).
In research that does take into account physical-layer aspects, the authors use very simple (and less accurate) isotropic path loss models, which are often unreliable in indoor environments.
Overlap paths supported by a single read were unreliable and were removed.
It assumes that sub-Saharan Africa will instead follow the path of Nigeria, where the country's notoriously unreliable demographic data suggest that a decline in fertility has stalled at about five children.
This kind of ventriloquism allows for savage satire, because the book is effectively one long skein of unreliable narration; the reader is forced to pick a desolate path through a wilderness that thinks itself a garden.
In sensornets with heterogeneous duty cycles, the heterogeneity of duty cycles and unreliable links collectively impact the network performance in terms of path delay, delivery ratio, and energy efficiency, in a sophisticated way.
