Security-Aware Dynamic Lightpath Allocation Scheme for WDM Networks

Abstract

In recent years, there is growing recognition of the need to develop suitable mechanisms for reducing the adverse effects of malicious attacks such as high power jamming and tapping attacks. A number of recent papers have proposed static lightpath allocation approaches that take such security issues into consideration. Most of these approaches consider the routing problem separately from the wavelength assignment problem. In this paper we propose a new security-aware ILP formulation, as well as an efficient heuristic for the complete security-aware dynamic routing and wavelength assignment (RWA) problem. To the best of our knowledge, this is the first such work to jointly consider in-band and out-of-band attacks, for either static or dynamic case.
