Protocols and resource allocation for future cooperative wireless networks

Wireless communications and network services are penetrating our society at an explosive rate, while the engineering community is setting ambitious goals for rapidly advancing their capabilities. My research program stems from two challenges in wireless communication systems and networks: first, wireless systems should deal with time-varying channel conditions; and second, the capacity of wireless communication is fundamentally limited by the spectrum bandwidth and transmission power. Therefore, efficient use of wireless resources is extremely critical. To that end, the main objective of my research program is to discover practical and near-optimal protocols and algorithms that can make timely decisions in response to changing environments in order to dynamically allocate resources of wireless networks. In addition, this research program will investigate fundamental and practical issues arising from dynamic resource allocation mechanisms.
