Fault-Tolerant Data Aggregation in Wireless Sensor Networks
نویسنده
چکیده
Accurate information is most important in Wireless Sensor Networks (WSNs). Incorrect (faulty data) information makes wrong decision; it decreases the reliability in communication. Fault tolerance is one of the issues in WSNs .Proposed fault tolerant data aggregation scheme for identifying the faulty data sent by the sensors to the cluster head, where the aggregation is performed. Identified faulty data eliminated before aggregation. It improves the data aggregation accuracy. Consequently, the transmission overhead is reduced. The proposed scheme provides better performance in discovering faulty data and nodes. The incorrect data detected and eliminated in wireless sensor networks. General terms Wireless sensor networks, Rough set theory.

This paper investigates the design of fault-tolerant TDMA-based data aggregation scheduling (DAS) protocols for wireless sensor networks (WSNs). DAS is a fundamental pattern of communication in wireless sensor networks where sensor nodes aggregate and relay data to a sink node. However, any such DAS protocol needs to be cognisant of the fact that crash failures can occur. We make the following ...
