Abstract

Several fully distributed measurement-based dynamic channel assignment (DCA) schemes are compared for the large-scale uncoordinated deployment of in-building microsystems: DCA based on the first quality of service (DCA-FQZOS) channel selection, DCA based on best QOS channel selection (DCA-BQOS), DCA-WO (channel) (DCA with weighted channel orderings), and DCA-WO (carrier) (DCA with weighted carrier orderings). The DCA schemes are evaluated in terms of their blocking probabilities and algorithm processing delay. We also investigate how the DCA performance depends on the number of radio ports per base station, asynchronous time-slot transmission, and propagation conditions. Of the proposed DCA schemes, the simulation results show that there are tradeoffs in selecting a DCA scheme. Finally, a new scheme called DCA with limited selection weighted ordering (DCA-LSWO) is proposed that combines some previous strategies to improve performance for in-building microsystems
