Abstract
A system is disclosed that improves quality-of-service (QoS) by parallel operation in a multiple access network and offers a flexible way to adjust network performance by dynamically allocating channels to be assigned dynamically to communicating nodes. The multiple access operation is improved via parallel operation for non-contending nodes, and smaller group of nodes for contention resolution. When a collision is detected by the communicating nodes in a communication system nodes engaged in a contention switch to a contention resolution channel to resolve contention while nodes not engaged in the contention continue their normal operation in the regular channel. After the contention is resolved and communication is accomplished, the nodes that have switched will switch back to their regular channel. Support of different service quality levels based on varying group size is made possible in a multiple access network while providing compatibility with existing protocol.
