QoS MANAGEMENT FOR MULTI-USER AND SINGLE USER EDCA TRANSMISSION MODE IN WIRELESS NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18154648 titled 'QoS MANAGEMENT FOR MULTI-USER AND SINGLE USER EDCA TRANSMISSION MODE IN WIRELESS NETWORKS
Simplified Explanation
The abstract describes a communication method in a network with multiple nodes, where each node has different traffic queues for serving data traffic at different priorities. The method involves computing queue backoff values based on queue contention parameters in different contention modes, and obtaining quality of service requirements for data stored in a traffic queue. If the requirements cannot be fulfilled using a second contention mode, access to resource units provided by other nodes is disabled within transmission opportunities granted to those nodes. Data stored in the traffic queue is then transmitted using a first contention mode.
- The method involves managing traffic queues in a communication network with multiple nodes.
- Queue backoff values are computed based on queue contention parameters in different contention modes.
- Quality of service requirements for data stored in a traffic queue are obtained.
- Access to resource units provided by other nodes is disabled if quality of service requirements cannot be fulfilled using a second contention mode.
- Data stored in the traffic queue is transmitted using a first contention mode.
Potential Applications
- This communication method can be applied in various network environments, such as wireless networks, cellular networks, or data centers.
- It can be used to prioritize and manage different types of data traffic based on their quality of service requirements.
Problems Solved
- The method addresses the challenge of managing data traffic at different priorities in a communication network.
- It ensures that quality of service requirements are met by dynamically adjusting the contention mode and resource access.
Benefits
- The method allows for efficient utilization of network resources by adapting to different contention modes.
- It ensures that data traffic with specific quality of service requirements is given priority, improving overall network performance.
- By disabling access to resource units when quality of service requirements cannot be fulfilled, it prevents degradation of service for other nodes.
Original Abstract Submitted
A communication method in a communication network comprising a plurality of nodes, at least one node comprising a plurality of traffic queues for serving data traffic at different priorities, each traffic queue being associated with a respective queue backoff value computed from respective queue contention parameters having first and second values in, respectively, a first and a second contention modes, obtaining quality of service requirements of data stored in a traffic queue of the node; checking whether the quality of service requirements can be fulfilled when accessing the communication channel using the second contention mode; if the requirements cannot be fulfilled as the result of the checking, disabling access to resource units provided by the other node within one or more transmission opportunities granted to the other node on the communication channel; and transmitting data stored in the traffic queue using the first contention mode.
