Wireless multimedia sensor network (WMSN) is an emerging type of sensor network that contains sensor nodes equipped with cameras, microphones, and other sensors producing multimedia content. These sensors require sufficient energy to acquire, transmit, and process heterogeneous and relatively large volume of raw data. Due to resource restrictions of wireless sensor nodes, it is important to minimize the amount of redundant data transmission so that the average sensor lifetime and the overall bandwidth utilization are improved. Data aggregation is vital in conserving energy by eliminating the inherent redundancy of raw data in WMSNs. While WMSNs incur high maintenance overhead in dynamic scenarios, WMSNs should be capable of timely fulfilling its mission without losing important information in event-based applications. This paper focuses on designing a tree-based data aggregation scheme. Using simulations, we investigate the performance of the data aggregation in terms of aggregation gain and energy consumption for WMSNs.
