Gl. Stuber et Mj. Ho, DISTRIBUTED DYNAMIC CHANNEL ASSIGNMENT FOR IN-BUILDING MICROSYSTEMS, IEEE transactions on vehicular technology, 47(4), 1998, pp. 1292-1301
Several fully distributed measurement-based dynamic channel assignment
(DCA) schemes are compared for the large-scale uncoordinated deployme
nt of in-building microsystems: DCA based on the first quality of serv
ice (DCA-FQOS) channel selection, DCA based on best QOS channel select
ion (DCA-BQOS), DCA-WO (channel) (DCA with weighted channel orderings)
, and DCA-WO (carrier) (DCA,vith weighted carrier orderings). The DCA
schemes are evaluated in terms of their blocking probabilities and alg
orithm processing delay. We also investigate how the DCA performance d
epends on the number of radio ports per base station, asynchronous tim
e-slot transmission, and propagation conditions. Of the proposed DCA s
chemes, the simulation results show that there are tradeoffs in select
ing a DCA scheme. Finally, a new scheme called DCA with limited select
ion weighted ordering (DCA-LSWO) is proposed that combines some previo
us strategies to improve performance for in-building microsystems.
