Abstract

In a wireless packet switched integrated service network, it is important to guarantee the quality of services, which makes it necessary to police the traffic at the edge of the network. It is a tremendous waste if the scheduler assigns a particular time slot to a mobile and the mobile does not have a packet to transmit in that time slot. It is equally wasteful if the mobile has a packet to transmit, but the packet is dropped, marked or delayed by the traffic regulator/policer in the base station. To avoid such inefficiency, we propose a joint control of the slot assignment to the mobiles and the policing of the traffic. We formulate integer nonlinear programming; to solve for the optimal joint control problem. We also use simulation to study several suboptimal heuristic joint control methods and compare them with the optimal control. Finally, we carry out a queueing analysis of the wireless multiple access system to capture the effect of joint control of slot assignment and traffic regulation
