Implementation and Evaluation of Resilient Network Based on Cognitive Wireless Network Framework

Since the conventional communication means are severely damaged and cannot be functioned at the occurrence of disaster, more robust and redundant information infrastructure has to be constructed to prepare the estimated large disasters. In this paper, we reported the implementations and evaluation of the resilient network system, which is based on cognitive wireless network framework in order to provide a robust and quick recovery from the damages. In the proposed methods, we introduced autonomous wireless link and path changes by the network environment and user policy changes, and the prototype is used for the evaluation of the proposed methods.
