Abstract

Applications of mixed integer optimization are in a period of rapid development due to a combination of improved modeling approaches, faster computational capabilities, and enhanced solving techniques. This enables problem modeling and solution from larger and more complex sets of alternatives which is attractive to address planning, design, and scheduling problems in the field of wireless networks. This talk discusses the utilization of mixed integer programs and solution techniques to address specific problems relevant to the design of next generation wireless networks. First, cooperative content distribution in wireless networks will be discussed for various design alternatives including optimal grouping of the mobile terminals, unicasting/multicasting communications and multihop cooperation. Second, the problem of radio network planning will be discussed including multi-technology co-siting and planning with green considerations. Optimized solutions, complexity analysis along with various polynomial time heuristic solutions will be presented and analyzed.
