False Data Detection Using Trusted Group Membership Service

Wireless sensor networks are vulnerable to many types of security attacks, including false data injection, data forgery, and eavesdropping. Sensor nodes can be compromised by intruders, and the compromised nodes can distort data integrity by injecting false data. The transmission of false data depletes the constrained battery power and degrades the bandwidth utilization. False data can be injected by compromised sensor nodes in various ways, including data aggregation and relaying. Because data aggregation is essential to reduce data redundancy and to improve data accuracy, false data detection is critical to the provision of data integrity and efficient utilization of battery power and bandwidth.
