Joint radio resource management based on the species competition model

For optimal radio resource utilization in heterogeneous wireless networks, joint radio resource management (JRRM) is required. In distributed JRRM, each radio each access network (RAN) adjusts network parameters to affect user´s RAN selection, thereby indirectly implementing joint radio resource allocation. The mathematical method for instructing such adjustment is lacking. In this article, the relationship between different RANs is mapped into the competition between species in the well-known L-V model developed by ecologists. Based on this model, an adjustment algorithm of distributed joint radio resource allocation is proposed. The simulation results show that compared with no adjustment or over adjustment, our adjustment algorithm can: 1) obtain proper resource allocation; 2) guarantee network coexistence
