An Optimal Agreement in a Cluster-based Wireless Sensor Network with Malicious Faulty Nodes

Abstract - A cluster of sensor nodes in Cluster-based Wireless Sensor Network (CWSN) is cooperating to achieve some objectives. For CWSN, the fault- tolerance and reliability has been an important topic. The problem of reaching agreement in the distributed system is one of the most important issues to design a fault-tolerance system. In previous works, reach a common agreement among healthy nodes to cope with the influence from faulty components is significant in a fault-tolerance system. In this study, the Optimal Malicious Agreement Protocol (OMAP) is proposed in a CWSN, which the sensor nodes maybe subject to Byzantine (malicious) failure.
