A Majority Voting Scheme in Wireless Sensor Networks for Detecting Suspicious Node

In wireless sensor networks, a majority voting scheme is proposed by us to identify the suspicious node. We take the cluster-head as the counter and see attested node as the voter. The attested information will be collected and counted by the cluster-head. The final voting result that is generated by the majority voting principle decides on the authenticity of suspicious node. Through the theory and the computation deducing, it can be demonstrates that the credible rate of voting scheme can surpass 90% in heterogeneous sensor network. Thus, our voting scheme for detecting suspicious node is more accurate and more reliable. It helps to improve the security of wireless sensor networks.
