Abstract

Wireless sensor networks (WSNs) are set to form a significant part of the new pervasive Internet, often referred to as the Internet of Things. WSNs have traditionally been powered by limited energy sources, viz. batteries, limiting their operational lifetime. To ensure the sustainability of WSNs, researchers have turned to alternative energy sources for power. Harvesting ambient energy from the environment to power WSNs is a promising approach, but it is currently unable to provide a sustained energy supply to support continuous operation. Sensor nodes therefore need to exploit the sporadic availability of energy to quickly sense and transmit the data. We first review the recent developments in energy harvesting technology and research on networking protocol design for WSNs powered by ambient energy harvesting. Then, we discuss some of the challenges faced by researchers in designing networking protocols and summarize the open research problems.
