Abstract:
Multilevel security serves a unique and vital function within a network: restricting access of users where necessary and protecting the flow of information between nodes. Such software-defined networks are marked by their central controller, which deploys rules on switches across the network. The advent of software-defined networks opened an avenue for a multilevel security algorithm managed by the central controller; said algorithm was defined as MLSnet by researchers at Penn State and boasts impressive improvements over similar algorithms. However, MLSnet has been primarily studied in wired networks with end nodes that do not move. In this work we expand the algorithm by considering wireless networks with end nodes that can move between access points, characterizing the overhead of MLSnet and its impact on performance with mobile users. Finally, we discuss methods for improving this performance.
