碩士 === 國立臺灣科技大學 === 資訊工程系 === 96 === In a typical wireless sensor network application, the sensor nodes collect environmental data and forward it back to the base station via multi-hop communications. Therefore, the traffic load on the nodes close to the base station is relatively heavier that an adversary may identify the location of the base station and cause security breaches by analyzing the traffic. In this thesis, we create traffic decoys that also sustain higher communication traffic to mask the location of the base station. Compared with previous approaches, our method provides defenses against adversaries with the global monitoring capability, and the true location of the base station is better protected.
