Ordinal optimization of admission control in wireless multihop voice/data networks via standard clock simulation

The authors study the voice-call admission control problem in integrated voice/data multihop radio networks. They develop an efficient simulation model based on the use of the standard clock (SC) approach, which permits the simultaneous simulation of a large number of admission-control policies, thereby reducing computation time significantly. They then demonstrate the effectiveness of ordinal-optimization techniques, which provide a remarkably good ranking of admission-control policies after relatively short simulation runs, thereby facilitating the rapid determination of good policies. Moreover, they demonstrate that the use of crude and inaccurate analytical and simulation models can provide highly accurate policy rankings that can be used in conjunction with ordinal-optimization methods, provided that they incorporate the key aspects of system operation
