Secure data aggregation using mobile agents in wireless sensor networks

Data aggregation is a widely used technique in wireless sensor networks. The security issues, data confidentiality and integrity, in data aggregation become vital when the sensor network is deployed in a hostile environment. There have been many related work proposed to address these security issues. In this paper, we introduce the concept of mobile agents for secure data aggregation in sensor networks. We propose an algorithm that can be used to track a malicious node in the network and hence maintain data confidentiality and data integrity in data aggregation.
