General hardware architecture of an energy-harvested wireless sensor network node (EH-WSN) can be divided into power, sensing, computing and communication subsystems. Interrelation between these subsystems in combination with constrained energy supply makes design and implementation of EH-WSN a complex and challenging task. Separation of these subsystems into distinct hardware modules simplifies the design process and makes the architecture and software more generic, leading to more flexible solutions. From the other hand, tightly coupling these subsystems gives more room for optimizations at the price of increased complexity of the hardware and software. Additional engineering effort could be justified by a smaller, cheaper hardware, and more energy-efficient a wireless sensor node. The aim of this paper is to push further technical and economical boundaries related to EH-WSN by proposing a novel architecture which-by tightly coupling software and hardware of power, computing, and communication subsystems-allows the wireless sensor node to be powered by a thermoelectric generator working with about 1.5 • C temperature difference while keeping the cost of all electronic components used to build such a node below 9 EUR (in volume).

Wireless sensor networks (WSNs) consist of a number of sensor nodes, which are able to collect information from the environment by measuring diverse environment variables, like temperature, humidity, sound etc. Sometimes the sensor nodes (SN) are expected to be deployed in unattended environments for long durations; the major challenge is tapping on ambient energy to power such networks. This paper investigates on providing dedicated power supply to all static sensor nodes (SN) through mobile power nodes (MPNs); which is equipped with solar cells and super capacitors to store harvested energy. The MPNs are used to supply energy to all other static sensor nodes which has energy below minimum threshold level. The super capacitor guarantees a longer lifetime in terms of charge cycles, it presents itself as a "green" technology compared to batteries and it has a wide range of operating temperature.
