Activity-based cloud sending: Push services for user device multiplicity

With increasing numbers of devices per user, data delivery and annoyance problems arise from sending real-time or near real-time application push notification messages to all these devices. This paper presents a push notification service approach that is based on a user-centric viewpoint to deliver notification messages to the right device at the right time. The approach increases the chances of a user to timely respond to a notification without annoyance. As side benefit, the overload on the server side can be significantly reduced in terms of minimizing unnecessary duplicate notification messages sent to an individual user´s multiplicity of devices. We exemplarily discuss a prototypical implementation based on cross-platform web technologies that can be readily implemented.
