Condition-based Key Dissemination Period Determining Method in Sensor Networks

Sensor networks have some security problems to use it in the real world. Sensor networks are typically deployed in open and unattended environment. Owing to these features, an adversary can compromise the deployed sensor node and inject a fabricated report with a malicious goal. One of the proposed solutions is a dynamic enroute filtering scheme. In this scheme, the determination of the point of the time for exchanging keys is important since it affects the detecting power. We propose the fuzzy rule-based determining method. The simulation results show that the proposed method can conserve energy, while provides sufficient detecting power.
