Energy-efficient broadcast-based event update dissemination

In this paper we study a power-efficient event update dissemination system in a data broadcast environment for time-critical observations. We propose an on-line algorithm that can produce efficient broadcast schedules to disseminate event updates in linear time. Our algorithm assigns clients to a particular channel from where they can monitor updates of interest to reduce the channel monitoring energy consumption. Our simulation results suggest that our algorithm drastically improves power efficiency compared to previous algorithms.
