Cross-Layer Optimization for Mobile Ad Hoc Networks Using SCA Compatible Smart Radio

Homeland Security/First Responder networks require increased bandwidth and reliable connectivity. Future networks such as Project SAFECOM may deploy software-defined radios (SDR) compatible with Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA). We leverage our SCA compatible, high assurance ¿Smart Radio¿ prototype being developed under an AFRL sponsored Phase II SBIR as a infrastructure testbed accesible by academic and industry researchers. Our prototype includes a CC EAL4+ laptop with SCA core framework, PCMCIA module with NSA Type I AIM CS/S, Xilinx Virtex II Pro FPGA, and a High Assurance Wireless Computing System (HAWCS¿) security layer which defeats blended wireless and Internet hacking attacks. In Phase I we define requirements and design cross-layer optimizer components, using MATLAB/SIMULINK to simulate their performance. COMMERCIAL APPLICATIONS: Develop innovative applications of mobile ad-hoc network (MANET) technologies to effectively increase the digital bandwidth and reliable connectivity to wirelessly connected users. Exploit the dense concentrations of wireless users to support high bandwidth but bursty applications such as image and video transfers. Develop new SCA compatible cross layer optimizing components which can be used in Smart Radio testbed. licensable commercial off the shelf (COTS) waveform stacks and JTRS waveform development. Develop SDR networking infrastructure testbed.
