Incumbent Detection and Avoidance

Description

Current and future wireless communication systems must provide for both higher mobility and greater functionality. They must support increasingly time-critical applications while remaining easy to maintain and administer. They must adapt appropriately and quickly to rapidly changing environments and new applications/user requirements. They must also be portable, low-cost, and have a long operating lifetime in the field. Satisfying these and other demands will require a systems approach that enables distributed detection of all types of events/changes, facilitates analysis  of the changes and their consequences, notifies all relevant systems of these changes, and coordinates a correct response to the situation. We thus propose to:

(1) Develop algorithms for distributed detection of incumbents in any frequency band of interest.

(2) Determine the correct response to detected incumbents.

(3) Utilize the eStadiumTM wireless testbed in Ross-Ade Stadium at Purdue to test algorithms.
