A fast and tolerant voting mechanism in wireless sensor networks

Abstract

In wireless sensor networks, the voting technique is used to extract a reliable result from redundant information. This paper proposes a fast and tolerant voting mechanism (FTVM), which greatly reduces the polling delay at one election with the CDMA technique. This work also adopts intrusion detection techniques to identity the compromised nodes and replaces them with backup nodes, such that the tolerance of the network is improved by a large degree. © 2011 Springer-Verlag.
