The phrase "active duration" is correct and usable in written English.
It can be used in contexts related to time management, project planning, or any situation where the length of time something is actively engaged or in use is being discussed.
Example: "The active duration of the project was six months, during which the team worked diligently to meet all deadlines."
Alternatives: "engagement period" or "operational time".
WI consists of two parts (Figure2): Active Duration and Inactive Duration.
The proposed scheme is designed to have variable active duration of nodes according to their variable traffic load.
However, if the active duration is a long interval, the reservation request message may be forwarded over a bigger number of hops reaching more nodes as well.
When this error exceeds a given threshold (selected by the designer), the synchronization process starts during the active duration in course.
When the active duration is a short interval, the reservation request message is forwarded covering few hops, and therefore few nodes.
Within the active duration all the nodes trying to transmit information compete for accessing to the physical medium according to the CSMA-CA mechanism.
Therefore, the number of synchronization processes on the closest nodes is reduced, leaving the available active durations for data message transmissions.
The variable active durations are assigned to the nodes based on node distance from the sink node, node topological importance, and occurrence of event in its vicinity.
It will enable the nodes to gracefully handle the traffic, as nodes are dynamically assigned active durations according to their expected traffic load.
Therefore, we must also take into account that the probability of transmitting the synchronization message is also conditioned to the occurrence of the synchronization event during the previous active durations, as Equation (2) indicates.
We noted no differences in average activity onset times, activity offset times, or overall active phase duration.
