Generalized Queue-Aware Resource Management and Scheduling for Wireless Communications

Location-Aware Dynamic Resource Management for High-Speed Railway Wireless Communications

With the fast development of high-speed railway (HSR), the demand for mobile communication on high-speed trains is increasingly growing. This leads to significant attention on the study of resource management in HSR wireless communications with limited bandwidth. Resource management is a challenging problem due to heterogenous quality of service (QoS) requirements and dynamic characteristics of...

Web Session-aware Queue Scheduling

本稿では過負荷時にWeb アプリケーションサーバの性能低下を防ぐ Session-aware Queue Scheduling(SQS)を 提案する.既存の多くのアドミッション制御はサーバ全体またはページを単位として制御を行うため,セッション を利用する現実のワークロードには適していない.実際のワークロードを重視したスケジューリングを行うために, SQS ではページ単位のスケジューラとセッション単位のスケジューラを連携させる.ページスケジューラはWeb アプリケーションの進捗を監視することで,最適なページ処理並行度を動的に決定する.セッションスケジューラ はページスケジューラの待機リクエストのためのキューを監視することで最適な同時セッション数を動的に決定す る.我々はこれらのスケジューラを Tomcat 上に実装し,セッションを考慮したワークロードを用いて実験を行っ た.その結果,S...

Human-in-the-Loop Wireless Communications: Machine Learning and Brain-Aware Resource Management

Human-centric applications such as virtual reality and immersive gaming will be central to the future wireless networks. Common features of such services include: a) their dependence on the human user’s behavior and state, and b) their need for more network resources compared to conventional cellular applications. To successfully deploy such applications over wireless and cellular systems, the ...

Channel Aware and Queue Aware Scheduling in LTE Uplink

Long Term Evolution (LTE) uses single carrier frequency division multiple access (SCFDMA) technique as the multiple access scheme in the uplink, due to its low peak to average power ratio (PAPR) compared to orthogonal frequency division multiple access (OFDMA). This advantage is achieved when the Resource Blocks (RBs) allocated to a user are contiguous in frequency domain. Considering this cons...
