Energy Management Techniques for RF-Enabled Sensor Networks Based on Internet of Things

The vision of ubiquitous computing is based on the fact that future computers will merge up with the surrounding environment in IoT domain. Radio Frequency Identification (RFID) and Wireless Sensor Networks (WSN) are two important cornerstones for pervasive computing as they combine the physical and virtual world, thereby bridging the gap between cyber space and physical world of real things. RFID enables the identification and detection of entities while WSN are used to sense the condition of the environment or object. The integration of RFID and WSN have paved way for the existence of RSN (RFID Sensor Networks), thereby providing extended capabilities, scalability, portability, lower cost and novel perspective towards a broad range of applications. This paper presents a brief introduction about the evolution of RSN, major issues in RSN and energy management with regards to Energy Harvesting (EH), energy request and transfer. It also investigates into the problems encountered for efficient energy transmission. Differently from the classic schemes in the literature that deals with scalability, security and communication protocol aspects, the proposed methodology focuses on energy management issue which is of utmost importance for wide area RSN. Furthermore, the paper provides insights into the preliminary experimental evaluation and its comparative analysis with existing schemes pertaining to performance metrics.
