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.
