Novel Energy Efficient Schemes for Wireless Sensor Networks Utilizing Mobile Sensors

Wireless sensor networks (WSNs) facilitate many applications in different fields and are well-known in both academic and industrial areas. The networks mainly include sensors, networking parts and a data processing center to collect data for a variety of purposes. However, the energy consumption problem in the networks is always a critical problem that many researchers are looking for good solutions. In this paper, we propose a data collection method that uses mobile sensors attached with bigger energy storages to collect data from static sensors. In addition, we propose a hybrid energy harvesting scheme to harvest energy from ambient environments to support static sensors to prolong the network lifetime. Some algorithms are provided to support the networks either with data collection or harvesting energy. We outline various possibilities for powering the gadgets with solar and RF energy gathering. In particular, all the circuits that are constructed using mathematical equations are offered. All of the network possibilities are clarified using simulation and experimental results. The outcomes are encouraging and useful.
