An En-Route Scheme of Filtering Data in Wireless Sensor Network

Monitoring and controlling physical systems through geographically distributed sensors and actuators have become an important task in numerous environment and infrastructure applications. Unlike more traditional embedded systems. The existing en-route filtering schemes are based on T authentication, i.e., a legitimate measurement report must carry at least T valid Message Authentication Codes (MACs) generated by different valid sensor nodes in CPNS, where T is the threshold and predefined before CPNS is deployed. When a report is transmitted from a sensor node to the controller, each forwarding node checks whether the forwarding reports actually carry T valid MACs.
