Traditional approaches to guarantee quality of service (QoS) work well only with predictable channel and network access. In wireless mobile networks, where conditions dynamically change as nodes move about the network, a stateless approach is required. As wireless networks become more widely used, there is a growing need to support advanced services, such as multimedia streaming and voice over IP. Since shared wireless resources are easily over-utilized, the load in the network must be controlled so that an acceptable QoS for real-time applications can be maintained. If minimum real-time requirements are not met, these data packets waste bandwidth and hinder other traffic, compounding the problem. To address this issue, we propose the Perceptive Admission Control (PAC) protocol. PAC monitors the wireless channel and dynamically adapts admission control decisions to enable high network utilization while preventing congestion. Through discussion and simulations, we show that PAC achieves this goal and ensures low loss and delay for all admitted flows.
