HARVESTING-AWARE ENERGY MANAGEMENT FOR TIME-CRITICAL WIRELES
SENSOR NETWORKS WITH JOINT VOLTAGE AND MODULATION SCALING
ABSTRACT:
As Cyber-Physical-Systems (CPSs) evolve they will be increasingly relied on to support time-
critical and performance- intensive monitoring and control activities. Further, many CPSs that
utilize Wireless Sensor Networking (WSN) technologies will require the use of energy
harvesting methods to extend their lifetimes. For this application class, there are currently few
algorithmic techniques that combine performance sensitive processing and communication with
efficient management techniques for energy harvesting. We first propose a general purpose,
multihop WSN architecture capable of supporting time-critical CPS systems using energy
harvesting.
We then present a set of Harvesting Aware Speed Selection (HASS) algorithms. Our technique
maximizes the minimum energy reserve for all the nodes in the network, thus ensuring highly
resilient performance under emergency or fault-driven situations. We present an optimal
centralized solution, along with an efficient, distributed solution. We propose a CPS-specific
experimental methodology, enabling us to evaluate our approach. Our experiments show that our
algorithms yield significantly higher energy reserves than baseline methods.
