A utility-based priority scheduling scheme for multimedia delivery over LTE networks
Date
2013
Abstract
With the mobile networks migrating towards LTE-Advanced and all-IP networks, people expect to connect to the Internet anytime, anywhere and from any IP-connected device. Moreover, nowadays people tend to spend much of their time consuming multimedia content from various devices with heterogeneous characteristics (e.g., TV screen, laptop, tablet, smartphone, etc.). In order to support uninterrupted, continuous, and smooth video streaming with reduced delay, jitter, and packet loss to their customers, network operators must be able to differentiate between their offerings according to device characteristics, including screen resolution. This paper proposes a novel Utility-based Priority Scheduling (UPS) algorithm which considers device differentiation when supporting high quality delivery of multimedia services over LTE networks. The priority decision is based on device classification, mobile device energy consumption and multimedia stream tolerance to packet loss ratio. Simulation results demonstrate the benefits of the proposed priority-based scheduling algorithm in comparison with two classic approaches.
