A Wireless Multimedia Sensor Network (WMSN) is often partitioned into a set of spatial clusters to save energy for data collection. Each cluster includes sensor nodes with similar sensing data, and only a few sensor nodes (samplers) report their sensing data to a base node. Then the base node may predict the missed data of nonsamplers using the spatial correlation between sensor nodes. The problem is that the WMSN is vulnerable to internal security threat such as node compromise. If the samplers are compromised and report incorrect data intentionally, then the WMSN should be contaminated rapidly due to the process of missed data prediction at the base node. In this paper, we propose Energy-Efficient Secure Routing algorithm to detect compromised nodes for secure data collection in the WMSN. Experiment results indicate that the proposed algorithm can detect compromised nodes with a high accuracy and an energy-efficient manner.
