Spectrum allocation in C-NEDAT: A tool to automate MANET design and opportunistically adapt network spectrum use

The advancements in cognitive radios coupled with the ever increasing demand for spectrum have propelled research into dynamic and adaptive spectrum management techniques. More specifically, the need to support a wide variety of network centric warfare(NCW) applications combined with the dearth in `available´ spectrum underscores the need for opportunistic spectrum use, whereby idle spectrum can be `borrowed´ used opportunistically by applications that need it. To this end, Telcordia and CERDEC have developed a cognitive network design tool called C-NEDAT to provide for a systematic method to design NCW-like networks. An important aspect that we address with C-NEDAT is spectrum assignment in multiple time scales.
