This paper demonstrates the advantages of using cognition when solving impairment-aware virtual topology design problems. Two new multiobjective cognitive genetic algorithms are presented and a performance comparison between them and a non-cognitive method is shown.
This article presents a new and robust watermarking method in the frequency domain that improves over the existing ones. It is robust to JPEG compression, very configurable, simple, efficient and very easy to implement. Apart from JPEG test, it shows very good results in all tests applied.
