Integer Linear Programming Optimization of Joint RRM Policies for Heterogeneous Wireless Systems
Wireless systems will be characterized by the coexistence of heterogeneous Radio
Access Technologies (RATs) with different, but also complementary, performance and technical
characteristics. These heterogeneous wireless networks will provide network operators the
possibility to efficiently and coordinately use the heterogeneous radio resources, for which novel
Joint Radio Resource Management (JRRM) policies need to be designed. In this context, this work
proposes and evaluates a JRRM policy that simultaneously determines for each user an adequate
combination of RAT and number of radio resources within such RAT to guarantee the user/service
QoS requirements, and efficiently distribute the radio resources considering a user fairness
approach aimed at maximizing the system capacity. To this aim, the JRRM algorithm, which takes
into account the discrete nature of radio resources, is based on integer linear programming
optimization mechanisms
