Energy harvesting for WSN and IoT: Recent advances and applications in smart cities
Energy efficiency in wireless sensor network (WSN) and Internet of Things (IoT) has been gaining increasing attention due to the limited battery powered devices. Notably, despite recent technological advances, batteries are expected to be consumed hastily for many applications. This problem is particularly severe when devices are deployed in hostile environments, where the replacement of batteries are prohibitively expensive and impractical. Therefore, energy efficiency is the main requirement in designing effective WSN/IoT structures for smart cities. The design of energy efficient protocols involves several aspects, including physical, MAC and network elements as well as application aspects.
Recently, energy harvesting (EH) has merged as a key approach that addresses the problem of restricted batteries by scavenging energy from ambient environments. Sensor networks and IoT devices can be made self-sustaining by harvesting energy from rich sources including solar power, electromagnetic waves, thermal energy, wind energy, salinity gradients, and kinetic energy. Continuously providing energy, and storing it for future use, energy- harvesting subsystems enable WSN and IoT devices to last potentially for a long time. Moreover, the advent of green communications also provides a strong motivation for developing energy harvesting based communication approaches. This has become mandatory due to the significant growth of energy-centric IoT applications.
The objective of this special session is to disseminate the latest research and innovations on energy harvesting systems and communications-based energy harvesting WSN and IoT for the smart cities. Suitable topics include, but are not limited to, the following:
