Monitoring the environment is one of the main applications of wireless sensor networks. Given that these networks are densely populated and that local variations in the environmental variables are small, a large amount of redundant data is generated by sensor nodes. In this paper we present a protocol for data dissemination in hierarchical sensor networks that integrates security and reduces communication overhead by removing data redundancy from the network. Furthermore, we show that by using
