Abstract:

Aiming at the problem of current false data filtering strategies that cannot prevent legitimate packets from discarded by the malicious nodes selectively, an en-route filtering strategy was put forward against selectively discarding packets. In this strategy, each node keeps its one-hop and two-hop neighbor nodes' identifications as well as one-way chain keys. Moreover, what the forwarded packets attached is the latest one-way chain keys of L nodes, not the message authentication codes in traditional en-route filtering strategies. Additionally, this strategy uses the stepwise certification to submit data packets by monitoring the communications between common neighbor nodes. Experiment shows that the strategy not only can efficiently filter false data, but also can prevent malicious nodes from selectively discarding packets.

Key words: wireless sensor networks, neighbor watch, selective discarding, en-route filtering
