RMVRVM – A Paradigm for Creating Energy Efficient User Applications Connected to Cloud through REST API

The applications that run on resource-constrained devices, especially for batteries, pose a challenge. The activities such applications do while running on such devices consume energy and drain the device's battery. Many of these applications use REST API to communicate with their backend services running outside of the devices, primarily on the cloud. The paradigms like Model View View-Model (MVVM) used on the application side require data transformations that cause applications to consume more battery. There is a need for an improved approach and a paradigm that can be used to develop green software with reduced battery consumption. This paper proposes a novel Remote-Model View Remote-View-Model (RMVRVM) paradigm. The use of RMVRVM paradigm lowers the battery consumption on devices where the application is running and hence contributes to writing green software. In addition, RMVRVM makes an application more responsive and thus a delight to use. This paradigm has been implemented in industrial case studies, and significant gains in terms of the reduced amount of data transfer, reduced battery consumption, and faster response time were observed. Experiments were also done to further validate the paradigm with encouraging results. The practitioners can apply the RMVRVM to design applications for battery-constrained devices with smaller energy footprints and better response times.
