Multi-Level Detection and Characterization Mechanisms against the Intentional Hidden Node Problem
ABSTRACT: The advent of cognitive radio networks (CRNs) presents myriad security threats, which inspires a growing need for increased capabilities for discovering and localizing non-cooperative nodes with either a selfish or malicious intent. In this proposal, Intelligent Automation, Inc. (IAI), along with its collaborators, propose to develop a Multi-Level Detection and Localization approach to defense against the intentional hidden node problem in CRNs. Our approach is based on our extensive investigation and understanding of the intentional hidden node problems in the context of CRNs, and utilizing mechanisms from multiple disciplines including RF characterization, anomaly/misuse detection, and localization. In Phase I, we have designed the system architecture and performed feasibility studies. In Phase II, we will implement a system prototype and test the system in terms of detection accuracy, efficiency, and robustness. BENEFIT: We note that hidden node detection and localization is a vital military issue that needs to be resolved. The proposed solution has potential to greatly tighten the security of future cognitive radio networks for military and commercial applications. Such potential DoD acquisition programs include but not limited to WIN-T, TTNT, WNW, N-CDL, JTRS GMR, and JTRS HMS. The proposed effort will provide an efficient detection and localization capability that enables secure CRN operation with heterogeneous communication demands in a distributed operation. There also exist a variety of commercial applications for the proposed multi-level hidden node detection system for heterogenous communications, such as transitioning this service to the communications industry for use in software-defined-radio (SDR) products and cellular networks. Packaging the proposed solution with the Commercial Off the Shelf (COTS) SDR hardware would increase the performance of standard networks. The defined market for SDR is rapidly expanding. Venture Development Corp. forecasts that the overall market for SDR will grow at a 31-percent rate from $2.2 billion (USD) in 2006 to nearly $10 billion by 2011. Such a large market need will help attract a great amount of potential investment.
