The explosive growth in the density of wirelessly connected devices and their traffic load is creating interference and gradually leading to a severe spectrum shortage. Approaches to address this challenge include dynamic spectrum allocation (cognitive radio) and pro-active interference mitigation strategies requiring coordination between heterogeneous networking technologies. In this project we are investigating and developing a modular and scalable methodology and architecture, called Connectivity Brokerage, that enables pro-active co-existence and collaboration between diverse technologies, making joint optimization of the scarce spectrum resources possible.
