  channel utilization
    The simulation results show that the strategy can reduce the new call blocking probability,improve the channel utilization and QoS while guaranteeing the handoff blocking probability compared with FCRS (fixed channel reservation scheme).
    仿真结果表明,与传统的固定分配预留保护信道FCRS(fixed channel reservation scheme)的策略相比,在保证一定切换呼叫阻塞概率的情况下,该策略能有效地降低新呼叫阻塞概率,提高信道利用率和系统的QoS(quality of service)。

  channel utilization
Experiments have been performed to measure the effectiveness of the priority system that use the mean access delay, throughput, and channel utilization as figures of merit.
      
The protocol also provides improved channel utilization with increasing high priority load, with no penalty in SP class performance at low to medium network loads.
      
This bound is then applied to the computation of the average channel utilization in a fully connected network with a large number of stations.
      
Simulation results show that M-EMAC outperforms EMAC in the wireless domain by improving channel utilization while reducing packet losses.
      
The channel utilization is examined analytically by introducing two capture models based on Rayleigh-distributed envelopes of the captured and the interfering frames divided into two local-mean power classes.
