Biologically inspired architecture for security management on wireless self-organized networks

This work presents SAMNAR, a survivable architecture for wireless self-organized networks (WSONs). SAMNAR is inspired on the human body immune system and focuses on providing network essential services, as link-layer connectivity, routing and end-to-end communication, even in the presence of attacks or intrusions. It employs a new approach for security management consisting in the coordinated use of preventive, reactive and tolerant defense lines in an adaptive way. The main goal lies in managing different levels of obstacles for attacks and intrusions, and adapting them when necessary. Based on SAMNAR, we present in this paper a path selection scheme for survivable routing as case study. Results show improvements in terms of security and performance, when SAMNAR approach is employed.
