Book excerpt: The application focus of our cross-layer design is towards enabling rapid, mobile-centric, handoffs in pseudocellular networks with small AP coverage areas as in Wireless Local Area Network technology, but supporting real-time applications under vehicular mobility as in cellular networks. To develop a design framework, we provide an analytical model of the cross-layer design that includes the new MPR and multiplicity feedback features and apply it to two classes of users: delay-constrained, Hi-priority users; and delay-tolerant, Lo-priority users whose throughput we wish to maximize, while guaranteeing QoS for the Hi-priority users. The channel throughput and the achievable QoS are characterized as functions of the arrival rates for Hi- and Lo-priority users and we obtain contention policies that ensure QoS and stability. Finally, we apply these methods to simulations of the DMMSE-based cross-layer design, and show that the analytical model provides accurate guidelines for design and performance predictions.
