Platforms and Testbeds for Experimental Evaluation of Cognitive Ad Hoc Networks
This paper reviews, discusses, and classifies the existing experimental platforms and testbeds for experimental evaluation of CR ad hoc networks. The paper first describes the internal organization of typical existing software defined radio platforms. Then, the existing software frameworks are discussed and classified. Consequently, the challenges involved in integration of these platforms to form multihop networks are discussed, and the major efforts for large-scale testbed implementations described. Finally, limitations of existing platforms and future research challenges toward the design of accurate open testbeds that will enable sound experimental evaluation of CR networks are discussed.
