For content request pattern, content requests are usually assumed to arrive in the network exogenously and the content request arrival process usually follows the Poisson process.
(a) Connection duration = 2 min. (b) Connection duration = 80 min. It is interesting to point out that owing to the issues that imply rekeying the end-to-end associations, a Poisson process was assumed to model the rekeying requests of the MNNs.
Only one user in relay set 1 is assumed to vary the data rate request, whereas all the other user requests remain unchanged.
To this, the overall power request was assumed to be satisfied in three possible ways: a battery (electric power system), a generator powered by a two-stroke internal combustion engine (thermal power system), and both battery and engine (hybrid power system).
Leaving a choice to the users to decide what and when should be requested is assumed to increase autonomous motivation of the user, which is more likely to lead to behavioural change [ 42, 43].
Users requesting inelastic services are assumed to have service rate target of 96 Kbps (e.g., simple video upload).
Note that for illustrative purposes we assumed that the page request phase cannot be done in a cooperative way, and the air interface should be used exclusively for each mobile device in this given phase, which can be assumed to be rather small.
Biographer John Canemaker assumed McCay's request to tour Europe was turned down, and that the refusal added to McCay's growing frustration with the Herald.
They know something is wrong but they don't… sometimes some people can't deal with it.' Such a response was particularly the case when patients wrongly assumed the request for a stool sample was linked to colorectal cancer screening.
In our simulation, we assumed that request arrival follows a Poisson process with an average arrival rate λ, and the request holding time follows an exponential distribution with an average holding time μ.
