Abstract :
A system of T resources (wireless channels) shared by a number of un-buffered applications is considered. The shared transmission resources are defined to be the slots (packet transmission times) of a TDMA frame (service cycle). Packets which are not allocated a channel within the current service cycle are dropped. The quality of service (QoS) vector is equivalently described in terms of (diverse) packet dropping probabilities (pi), or (diverse) packet dropping rates (di). From a precisely defined region of achievable QoS vectors, easy to implement scheduling policies that deliver the achievable QoS vectors are derived. As an example, a policy that delivers a target QoS vector is derived; its performance is verified through simulations
