Research on biological immunity principle based security model for Wireless Sensor Network

Wireless Sensor Network is typically a distributed system. It has the features of self-organization, sensor node collaboration and dynamic network topology. All these characters are quite similar to the biological immunity system. In this paper, we use the biological immunity principle for reference and propose a data-centric security immunity model for wireless sensor network. Sensor nodes can recognize the non-self node and its data by digital gene and behavior mode determinant. An immune response strategy is also included into this security immunity model. It can defend against the intrusion node and minimize the influence of malevolence data.
