A Malicious AgreementMalicious Agreement • January 9th, 2012
Abstract—A Wireless Sensor Network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions. Usually, as they are deployed to an open and unprotected region, they are vulnerable to various types of attacks. For wireless networks, a stable topology is an important research topic that provides good environment for transmission data in WSN. Further, the fault-tolerance and reliability of the WSN 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 agreement problem is revisited in a WSN, which the sensor nodes maybe subject to Byzantine (malicious) failure.
