Benefits of technology

This invention relates to methods or systems used with mobile devices such as smartphones to improve their performance and reduce power consumption during data communication sessions between them. It involves updating MAC layers based upon failures detected from received packets instead of relying solely on previous ones. By doing this, it ensures fair competition across multiple user groups while reducing energy usage compared to traditional techniques like random backoff.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving media access control protocols' ability to distinguish between high or low user preferences while ensuring fairness across diverse applications like audio streaming over mobile phone connections. Current methods require specific settings when transmitting packets through these protocols due to their fixed nature.

Abstract

A method provides differentiated quality of service (QoS) by providing adaptive updates to media access control (MAC) layer parameters on a distributed basis. The method includes calculating a failure probability for a transmission over the network, determining a target value for determining a contention window according to a mapped function of the failure probability, and altering the contention window according to a scaling function of the target value. The mapped function and the scaling can provide QoS differentiation. A wireless device ensures fairness in a wireless time slotted network and includes a network interface card (NIC), a network driver interface, a network monitor, a statistics engine, and an adaptive parameter engine for determining a target value for determining a contention window according to a mapped function of the one or more probabilities to enable an alteration of the contention window and provide new parameters for the MAC layer.
