In context-aware monitoring and control applications, multimedia data generated by multimedia sensors at a critical moment have to be delivered to a server reliably with tight time constraint. However, it is challengeable to process those data using a wireless multimedia sensor network with limited resources in terms of energy, bandwidth and processing power. Therefore, in this paper, we propose an energy-aware approach to deliver those event-driven bursty data in a reliable and timely manner by exploiting the advantage of slot scheduling technique and channel allocation. Our approach enables the concurrent transmission of a burst of multimedia data in order to shorten the multimedia data acquisition time and reduce the energy consumption. The simulation results show that the proposed approach can satisfy the requirements of multimedia applications in terms of data acquisition time and energy consumption compared with other approaches.
