    TCP-Aware Backpressure Routing and Scheduling

    Full text link
    In this work, we explore the performance of backpressure routing and scheduling for TCP flows over wireless networks. TCP and backpressure are not compatible due to a mismatch between the congestion control mechanism of TCP and the queue size based routing and scheduling of the backpressure framework. We propose a TCP-aware backpressure routing and scheduling that takes into account the behavior of TCP flows. TCP-aware backpressure (i) provides throughput optimality guarantees in the Lyapunov optimization framework, (ii) gracefully combines TCP and backpressure without making any changes to the TCP protocol, (iii) improves the throughput of TCP flows significantly, and (iv) provides fairness across competing TCP flows

    Enhancing Integrated Communication Network Service Using a Queueing Model

    This paper describes a strategy for efficiently constructing the demand servicing process of an Integrated Communication Network (ICN). Performance analysis, service problems, and relief action of ICNs are provided. End-to-end statistical performance parameters are first used to measure network compliance over a given fixed period. If any of the performance objectives are not satisfied, a servicing function determines the corrective action required to maintain service quality. The advantage of this network model is its efficiency and flexibility in handling a variety of services and applications. Enhanced network service and ICN traffic problems are solved using adaptive queuing models
