Abstract: A false report filtering scheme based on neighbor watch was proposed, in which information from two-hop neighboring nodes was stored, which included IDs and MACs of T nodes from different zones. Each forwarding node sent an ACK message to its upstream node after sending a report to its downstream node. False reports generated with keys from other zones would be detected by the one-hop neighbors of the malicious node. Meanwhile, forwarding nodes and the Sink would verify the authenticity of other reports. Analysis and experimental results show that this scheme improves filtering efficiency significantly, thus reducing the impact of malicious nodes and extending the life of the sensor network.

Key words: wireless sensor networks, neighbor watch, two-hop node information, false data filtering
