Back to Results Prototyping an Energy Harvesting Wireless Sensor Network Application Using HarvWSNet

International audienceIn this article, the HarvWSNet simulation framework is used to explore the feasibility of a structural health monitoring application based on a wireless sensor network. The aim is to show the value of a simulation-based approach for the architecture exploration and prototyping of severely energy constrained applications. In the target application, each network node performs a reading of temperature and/or acceleration and transmits the data to a base station every given period. A second objective of this work is to test the relevance of a power management algorithm whose role is to adapt the application quality of service to the instantaneous state of the energy harvesting module. The final goal is to propose a perpetually powered node architecture compatible with the user application requirements

A proposal for an Internet of Things-based monitoring system composed by low capability, open source and open hardware devices

The Internet of Things makes use of a huge disparity of technologies at very different levels that help one to the other to accomplish goals that were previously regarded as unthinkable in terms of ubiquity or scalability. If the Internet of Things is expected to interconnect every day devices or appliances and enable communications between them, a broad range of new services, applications and products can be foreseen. For example, monitoring is a process where sensors have widespread use for measuring environmental parameters (temperature, light, chemical agents, etc.) but obtaining readings at the exact physical point they want to be obtained from, or about the exact wanted parameter can be a clumsy, time-consuming task that is not easily adaptable to new requirements. In order to tackle this challenge, a proposal on a system used to monitor any conceivable environment, which additionally is able to monitor the status of its own components and heal some of the most usual issues of a Wireless Sensor Network, is presented here in detail, covering all the layers that give it shape in terms of devices, communications or services
