Special Issue Information

Dear Colleagues,

A lot of platforms for wireless sensor networks (WSNs) are designed to run on batteries, which have a very limited lifetime. This energy constraint causes a severe problem for applications in which a sensor system is supposed to operate for long periods. Longer lifetimes are necessary if WSNs are to become a ubiquitous part of our environment. While a lot of effort has been put into developing techniques to make more efficient use of limited amounts of energy, alternative power sources will eventually need to be employed.

Environmental energy has recently emerged as a feasible supplement to battery power for wireless sensor systems where manual recharging or replacement of batteries is not practical. Since solar energy has a high-power density (compared to other renewable energy sources) and a periodic charge cycle, it is one of the most attractive energy sources. Therefore, we invite cutting-edge scientific researchers to draw a picture of the use of solar energy to WSNs. Topics of interest include, but are not limited to, the following research issues:

  • Network-wide distributed protocols to enhance QoS for solar-powered WSNs (e.g. routing protocol, MAC protocol);
  • Resource management for energy neutral operations;
  • Advancements on circuits of solar-energy harvesting for embedded systems;
  • Power management algorithms for solar-energy harvesting sensing systems;
  • Architectures for energy-neutral sensing systems;
  • Middleware support for interoperability among WSNs using heterogeneous energy sources;
  • Online measurement and forecasting algorithms of solar energy intake and consumption;
  • Simulation tools and modelling of solar-powered WSNs;
  • Practical deployments and implementation experiences.

The Internet of Things (IoT) is demonstrating its huge innovation potential, but at the same time, its spread can induce one of highest environmental impacts caused by the IoT industry. This concern has motivated the rise of a new research area aimed at devising green IoT deployments. Our work falls in this research area by contributing to addressing the problem of assessing the environmental impact of IoT deployments. Specifically, we propose a methodology based on an analytical model to assess the environmental impact of an outdoor IoT deployment powered by solar energy harvesting. The model inputs the specification of the IoT devices that constitute the deployment in terms of the battery, solar panel and electronic components, and it outputs the energy required for the entire life-cycle of the deployment and the waste generated by its disposal. Given an existing IoT deployment, the models also determine a functionally equivalent baseline green solution, which is an ideal configuration with a lower environmental impact than the original solution. We validated the proposed methodology by means of the analysis of a case study conducted over an existing IoT deployment developed within the European project RESCATAME. In particular, by means of the model, we evaluate the impact of the RESCATAME system and assess its impact with respect to its baseline. In a scenario with a 30-year lifespan, the model estimates for the system more than 3 times the energy required by its baseline green solution and a waste for a volume 15 times greater. We also show how the impact of the baseline increases when assuming deployments in locations at increasing latitudes. Finally, the article presents an implementation of the proposed methodology as a web service that is publicly available. Full article
