In wireless sensor networks, adversaries can injectfalse data reports via compromised nodes and launch DoS attacks against legitimate reports. Recently, a number of filtering schemes against false reports have been proposed. However, they either lack strong filtering capacity or cannot support highly dynamic sensor networks very well. Moreover, few of them can deal with DoS attacks simultaneously. In this paper, the authors propose a dynamic en-route filtering scheme that addresses both false report injection and DoS attacks in wireless sensor networks.
