An MDP-Based Dynamic Optimization Methodology for Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are distributed systems that have proliferated across diverse application domains (e.g., security/defense, health care, etc.). One commonality across all WSN domains is the need to meet application requirements (i.e., lifetime, responsiveness, etc.) through domain specific sensor node design. Techniques such as sensor node parameter tuning enable WSN designers to specialize tunable parameters (i.e., processor voltage and frequency, sensing frequency, etc.) to meet these application requirements. However, given WSN domain diversity, varying environmental situations (stimuli), and sensor node complexity, sensor node parameter tuning is a very challenging task.
