Complete sharing versus partitioning: quality of service management for wireless multimedia networks

This paper is concerned with performance and quality of service (QoS) guarantees for wireless networks that support multiple types of traffic. QoS is maintained by a distributed adaptive event-based admission control scheme. We compare the case where cell capacity is completely shared by the calls to the case where the cell capacity is partitioned for different types of traffic. Complete capacity sharing networks may give higher system utilization due to statistical multiplexing gain, but need to adopt the tightest QoS bound among all traffic types. Partitioning will result in a less complex management system which provides independent QoS controls for different traffic types at the expense of possible lower overall utilization. The analytic results are verified by simulation experiments.
