Table 1 Variable symbols and their meanings
From: Energy-efficient capture of stochastic events based on on-line scheduling scheme
Symbol | Meaning |
|---|---|
 r | Sensor perception radius |
k1 | Energy rate of sensor consumed in active state |
k2 | Energy rate of sensor consumed in inactive state |
 c | Energy consumed by the sensor to change between active/inactive states |
 ν | Average arrival rate of stochastic events at PoI |
 X | The time of an event arrives PoI and lasts for a stochastic event, that is, the duration of stochastic event |
 Y | The interval between the of disappearance of previous event and the arrival of latter event at PoI, that is, the interval between stochastic event |
Pc | Capture probability of stochastic events from arrival PoI until disappearance |
QE | Energy efficiency of sensor in capturing stochastic events |
