The signal tracking accuracy in the magnitude-driven sampling scheme

The paper discusses the possibility of the analytic design of the discrete-event state space in the event-driven sampling scheme to approximate the continuous-time signals monitored by the sensor node. The sufficient and the necessary conditions for threshold selection are specified. The accuracy of the analytical approximation of the mean sampling rate is discussed. The maximum overestimation of the real observation traffic for narrow-band signals is derived. The analysis is based on the analytic approach and the simulation verification.
