Abstract

Clustered routing protocols in wireless sensor networks (WSN) provide significant advantages in energy saving and data preprocessing. However, the communication greatly depends on cluster heads, which leads to severe security problems. In order to solve this problem, a clustered routing protocol with distributed intrusion detection for WSN (WSN_DID) is proposed in this paper. In WSN_DID all nodes are organized to identify intruding cluster heads in a distributed way by predistributed random keys. The experiments demonstrate that compared with classic cluster-based routing protocol in WSN, energy dissipation in WSN_DID is rather less and the toleration of intrusion is elevated.
