In this work we report on the analysis, from an energy consumption point of view, of two communication methods in the Web-of-Things (WoT) framework. The use of WoT is seducing regarding the standardization of the access to things. It also allows leveraging on existing web application frameworks and speed up development. However, in some contexts such as smart buildings where the objective is to control the equipments to save energy, the underlying WoT framework including hardware, communication and APIs must itself be energy efficient. More specifically, the WoT proposes to use HTTP callbacks or WebSockets based on TCP for exchanging data. In this paper we introduce both methods and then analyze their power consumption in a test environment. We also discuss what future research can be conducted from our preliminary findings.
