Abstract :
This paper develops an analytical model for evaluating the quality of service (QoS) in wireless ad-hoc networks. In doing so it extends the trunking theory concepts to encompass the effect of co-channel interference. Chosen as the QoS figure of merit, the transmission blocking probability is derived as a function of the number of nodes, the network density and parameters of a Markov chain model for the multiple user channel access protocol. This expression is validated by computer simulations.
