Different ways to simultaneously control event sensing reliability and device utilization in a beacon-enabled IEEE 802.15.4 sensor cluster are investigated. Activity management is achieved through probabilistic control of the duration of active and inactive (i.e., service and sleep) periods. The probabilistic control parameters are derived as functions of the required event sensing reliability, device utilization, medium access control and physical layer parameters, and network size
