Many data dissemination techniques have been proposed for wireless sensor networks to facilitate data dissemination and query processing. However, these techniques may not work well in a large scale sensor network where a huge amount of sensing data are generated. In this paper, we propose an integrated distributed Connected dominating set Based Indexing (CBI) data dissemination scheme to support scalable handling of large amount of sensing data in large scale wireless sensor networks. Our CBI can minimize the use of limited network and computational resources while providing timely responses to queries. Moreover, our data dissemination framework ensures scalability and load balance. Analysis and simulations are conducted to evaluate the performance of our CBI scheme. The results show that the CBI scheme outperforms the external storage-based scheme, local storage-based scheme and the data-centric storage-based scheme in overall performance.
