Abstract : In this report, we investigate the admission control problem for voice traffic in integrated multihop radio networks. We consider only those admission control policies that yield a 'coordinate convex' state space. This restriction, in conjunction with the use of a 'blocked-calls-cleared' mode of operation and the assumption that the voice process is Markovian, results in a product-form stationary distribution for the voice state of the system. The product-form distribution allows the straightforward evaluation of network performance when subject to different admission control policies. A large number of coordinate convex admission-control policies must be searched to determine the optimal policy. We develop a recursive procedure to speed the evaluation of a large number of different policies, as well as descent-search method to reduce significantly the number of policies that must be evaluated in searching for the optimal one. The numerical examples we present indicate that improved performance can be obtained by administering admission control, but this improvement is typically small unless different revenues or costs are associated with the various call types....
