Abstract: Wireless sensor networks (WSN) constitute a key technology for many applications that require virtual-physical interactions, such as military surveillance, environmental monitoring, home automation and health monitoring. For many long-term applications, a severe bottleneck is the limited amount of energy provided by individual batteries commonly used to power WSN. Energy harvesting forms a promising technology to tackle this problem. Moreover, the most energy consuming task in a wireless node is usually communication. Recent improvements in wake-up receivers (WURx) hardware make them a privileged direction to reduce the consumption of radio on wireless nodes. Using both technologies can enable WSN to achieve long term sustainability while maintaining quality of service requirements fulfilled. However, this requires careful design of both power managers (PMs) and MAC protocols to efficiently use these two emerging technologies together. The aim of our work is to design efficient PMs and MAC protocols for multihop energy harvesting wireless sensor networks (EH-WSN) in which each node is equipped with a WURx. In this paper, we present the energetic model and two PMs on which we are currently working on.

Abstract: In last years, the wireless sensor networks (WSNs) have take the interest of researchers since they have a number of potential applications in many domains of daily-life such as environment monitoring, healthy monitoring, medicine, surveillance, military, etc. The innovation of digital electronics, micro controller, wireless communications have facilitated the development of small tiny devices with these characteristics: low-cost, low-power and multi-functional. Due to the small size and the difficult access of a sensor node, the power source has limited capacity and can- not be replaced (non-replaceable). Therefore, energy consumption is an important constraint in WSNs. Energy harvesting (from many natural environment re- sources such as the heating, the sun light, the wind etc.) provides an effective option to increase the life- time of the sensor network but it is not a complete solution. In some cases, these resources are not enough to be ensure a sufficient reliability. Thus the reduction of energy consumption is still one important focus of research in WSNs domain.
