Abstract: The data in the Internet of Things needs to be aggregated and disseminated effectively．There are always central massive storage to manage the numeric data produced by sensors．Proper data forwarding mechanism is necessary for such a system．We proposed a design of content-based data forwarding network．This network can combined with the node network of massive storage,that is,utilizing the scattered computing resources of each node in a massive stora-ge network to take up the challenging task of dissemination of a great amount of data．Inspired by the system virtuali-zation,we introduced "workers" and "function bricks" to dynamically balance the loads of different nodes and tasks between nodes in the network automatically．We also proposed a distributed content-based publish/subscribe algorithm using Bloom filter．By efficiently using Bloom filter to represent the object as well as the set of constrains which is satisfied by the object,a large number of redundant computing can be eliminated to sure the algorithm’s efficiency.
