According to the strategy mobile application scenario, when a user detects more high quality communication links, its movement state tends to be stable, i.e., the probability of large-scale stochastic move is relatively low.
That is, if there is a malicious user detected in the system, they have to reset their encryption system to revoke the user.
Traditional detection probability can be defined as the probability that a secondary user detects a primary signal under the condition that the primary signal occupies the channel during the sensing duration[3 5, 10].
The probability that a secondary user detects the primary signal within n detection opportunities, P d (n), is given by P d n = ∑ i = 0 n P d, i = 1 − 1 − p d n. (4).
If the residual number of sensing periods overlapped with a primary signal until the primary signal disappears is n (say that a secondary user has n detection opportunities), then the probability P d,i that a secondary user detects the primary signal at its i th detection opportunity is P d, i = { p d 1 − p d i − 1, if 1 ≤ i ≤ n, 0, otherwise ( n = i = 0 ).
If a femtocell user detects that the femto signal is going down, the MS sends a report to the connected FAP (steps 1 and 2).
If a femtocell user detects that the femto signal is going down, the MS sends the report to the connected FAP (steps 1 and 2).
The intent is well-meaning: a sensor behind the user detects when they move away and the flushing occurs automatically.
On the other hand, if a user is detected to be walking, biking, or riding in a vehicle, the app starts logging location data.
"In contrast to a search of a home or a seizure of physical property, there may be no way for a user to detect that the provider has disclosed information stored in the account to the government," the brief filed by Amazon, Google and others said.
