Abstract
In Heterogeneous Networks (or HetNets), resources (both bandwidth and power) are apportioned by the Macro Base station to multiple User Equipments (UEs) with the intention of providing maximum possible date rate to all UEs. Concurrently, UE’s received power has to be above its receiver sensitivity. In addition, cross-tier co-channel interference to the nearest Femto Base station must be limited. This resource allocation problem is solved using Particle Swarm Optimization (PSO) method. However, this paper procures optimal solution with lesser number of iterations by properly choosing minimum and maximum possible powers in PSO.
