abstract = {This paper provides network designers and
operators with simple guidelines on traffic measurements and efficiency
evaluation of various channel allocation schemes in digital mobile
telecommunications networks. The paper evaluates the efficiency obtained by
implementing the following channel allocation schemes: (1) fixed uniform channel
allocation (FUCA); (2) fixed nonuniform channel allocation (FNCA); (3) dynamic
channel allocation (DCA) where the number of frequency carriers is adaptive and
dependent on the load; and (4) dynamic frequency/time channel allocation (DFTCA)
(a new scheme which is the most efficient) where the number of channels is
adaptive (based on the load), allowing two channels of the same frequency
carrier to be used in two neighboring cells. The analysis is based on standard
queuing models under the following assumptions: (1) Poisson call arrivals in
each cell; (2) exponential call holding time; (3) exponential mobile travel
time; and (4) exponential sojourn time of a mobile in a cell. Numerical results
are presented to provide insight into the accuracy of the models and efficiency
gain by dynamic frequency time channel allocation under different traffic
conditions (including conditions related to highway traffic).}
