Abstract:
As the energy consumption in an energy harvesting wireless sensor network is constrained, applications that can run on the nodes are limited as well. Thus, it is not only important to know how much energy can provide a harvesting system, but also how much energy will consume a specific application running on a node, and match both models to achieve a functional system from an energy point of view. Much literature can be found regarding energy harvesting models to predict energy produced but little about how this energy will be used. This paper presents an energy consumption model for nodes in a Wireless Sensor Network (WSN), which depends solely on the Duty Cycle. Likewise, applications are characterized for their duty cycle and this parameter will determine if a particular application can run on the node. The novelty of this model is the division of the duty cycle into smaller duty cycles for each of the WSN application components, allowing more control over the energy consumption. To the best of our knowledge, no other related studies have been carried out so far and we believe that this approach will contribute to develop applications for energy constrained system according to a maximum duty cycle. This approach has been tested against real data showing a relative error up to 3.14%.
