Radio Environment Map Based Radio Resource Management in Heterogeneous Wireless Network

Abstract

This work uses radio environment map (REM) to allocate spectrum dynamically among the heterogeneous base stations (BSs) within a particular geographical area. With the knowledge of BSs location and their power models, this work first forms a REM of the corresponding coverage area by considering serving BS and interfering BSs, then uses this REM for radio resource management (RRM) among different BSs to minimize outage probability and reducing service blocking to the users. The simulation result shows that the REM-based resource allocation performed better with increasing complexity.
