Integrated Fuzzy Control to Power Management on Event-Based Sensor Node.

This paper demonstrates how a fuzzy controller based dynamic power management (FCDPM) model for wireless sensor node saves a significant amount of power than traditional systems. The stochastic behavior of input event arrival is modeled with first-in-first-out (FIFO) queue and single server handled with FCDPM that improves lifetime and minimizes the delay in servicing the events. Compared with the previous research on power consumption of a wireless sensor node, this SimEvents model gives an easier implementation of sensor node with its system-level performance metrics in terms of power consumption, delay, lifetime and processor utilization for non-stationary workloads. The power saving of a single sensor node is analysed for forest fire detection and it can be further implacable in several energy-hungry wireless sensor network applications. [ABSTRACT FROM AUTHOR]
