With the inclusion of usage data, App Annie's dashboard now shows total sessions, total time, average sessions per user (per day, week or month), average session duration, and active user data (DAU, WAU, or MAU).
The Web session and shopping cart examples are also representatives of another common key-value use case: the stored information is needed for a limited period of time only (the duration of the user session).
A Temp ID uniquely identifies a patient for the duration of a user session and is implemented as a hash value or a universally unique identifier (UUID) of sufficient length to prevent brute-force attacks.
In both experiments, each user was initially assigned a random application and a session duration of 15 minutes.
The session initialization constraint is 50 ms and the average session duration 40 s. Figure 9 shows the accumulated number of accepted user session requests over time.
The numerical examples therefore consider Φ(n) = n / 2 allocatable users, m = 10 waveform tasks, and 1 / μ = 40 s average data session duration.
The networks, revealing very different application mixtures, are investigated in terms of session duration and data volume, packet size distribution, application usage frequency and data volume, as well as user mobility.
User connection times and session durations are sampled from a Gaussian distribution (standard deviation 0.5), except for casual and power users, whose connection times are drawn uniformly from the [8,21] and [0,24] hour ranges, respectively.
Session duration was 45 minutes, 3 sessions per week.
To consider the high dimensionality of user session data, we propose a fuzzy approach for assigning weights to user sessions.
