Download or read book QoS Based Centralized Routing in Wireless Hybrid Networks written by Sandeep Adimadhyam and published by . This book was released on 2008 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in wireless networking facilitated high speed wireless communication through various personal handheld devices supporting voice, data and other high bandwidth applications. Coverage and quality of service have become key requirements. Wireless Hybrid Networks facilitate seamless internet access to various devices with a wireless interface through multiple short hops. Routing in such multi-hop networks, supporting high bandwidth applications, is challenging due to the interference, mobility of nodes and delay. QoS based routing is one such effort to find optimal route from a source node to an access point to meet desired QoS criterion. QoS based routing requires a quality metric. In this research, various quality metrics in place were studied. A link quality metric based on models for interference and average delay, developed from simulation studies had been proposed. A centralized search for routes was implemented. This search selects routes based on their quality figure and also the overall performance of the network. The search was performed for multi-channel multiple access point and multiple user node scenarios. The results obtained were tabulated compared with those from computer simulations.

Download or read book Future Intent Based Networking written by Mikhailo Klymash and published by Springer Nature. This book was released on 2021-12-09 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: So-called Intent-Based Networking (IBN) is founded on well-known SDN (Software-Defined Networking) and represents one of the most important emerging network infrastructure opportunities. The IBN is the beginning of a new era in the history of networking, where the network itself translates business intentions into appropriate network configurations for all devices. This minimizes manual effort, provides an additional layer of network monitoring, and provides the ability to perform network analytics and take full advantage of machine learning. The centralized, software-defined solution provides process automation and proactive problem solving as well as centralized management of the network infrastructure. With software-based network management, many operations can be performed automatically using intelligent control algorithms (artificial intelligence and machine learning). As a result, network operation costs, application response times and energy consumption are reduced, network reliability and performance are improved, network security and flexibility are enhanced. This will be a benefit for existing networks as well as evolved LTE-based mobile networks, emerging Internet of Things (IoT), Cloud systems, and soon for the future 5G/6G networks. The future networks will reach a whole new level of self-awareness, self-configuration, self-optimization, self-recovery and self-protection. This volume consists of 28 chapters, based on recent research on IBN.The volume is a collection of the most important research for the future intent-based networking deployment provided by different groups of researchers from Ukraine, Germany, Slovak Republic, Switzerland, South Korea, China, Czech Republic, Poland, Brazil, Belarus and Israel. The authors of the chapters from this collection present in depth extended research results in their scientific fields.The presented contents are highly interesting while still being rather practically oriented and straightforward to understand. Herewith we would like to wish all our readers a lot of inspiration by studying of the volume!

Download or read book QoS aware Routing in Future All IP Access Networks written by Alexandre Jaron and published by . This book was released on 2015 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research is to propose a novel QoS mechanism for mobile networks. The new scheme is composed of two different approaches accountable for QoS provisioning in next-generation access networks. Firstly, a new method is proposed that minimises the signalling overhead, as well as the interruption in QoS at the time of handover. Through a developed analytical framework and simulation scenario, the performance of the new scheme is investigated thoroughly, with the focus on the figures of merit that affect the efficiency of using QoS signalling protocols in access networks. Secondly, a new QoS-aware routing mechanism is proposed, based on the OSPF protocol, intending to minimise the congestion on the links while at the same time complying with traffic requirements. OSPF was created for providing flexibility and great scalability, and although widely used today, does not allow arbitrary splitting of traffic.

Download or read book Throughput Optimal Routing in Wireless Ad hoc Networks written by Hairuo Zhuang and published by . This book was released on 2010 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation considers the problem of routing multi-commodity data over a multi-hop wireless ad-hoc network. The few well-known throughput optimal routing algorithms in literature are all based on backpressure principle, which shows poor delay performance under many network topologies and traffic conditions. In contrast, heuristic routing algorithms which incorporated information of closeness to destination are either not throughout optimal or the thoughts optimality was unknown (e.g. opportunistic routing policy with congestion diversity aka. ORCD). The primary goal of this dissertation is to find routing policies beyond backpressure type that not only ensure throughput optimality but also maintain satisfactory average delay performance. In the single commodity scenario, by considering a class of continuous, differentiable, and piece-wise quadratic Lyapunov functions, we propose a large class of throughput optimal routing policies called K policies, which include both backpressure algorithm and ORCD as special cases. The proposed class of Lyapunov functions allow the routing policies to control the traffic along short paths for a large portion of state-space while ensuring a negative expected drift, hence, enabling the design of routing policies with much improved delay performances. We then extend K-policy to multi-commodity case by considering nonquadric Lyapunov functions. A multi-commodity version of ORCD algorithm is proposed based on the generalized K-policy and is shown to be throughput optimal under mild conditions. Interestingly, the algorithm selects the commodity that has the maximum backlogs ratio instead of the maximum difference of backlogs as in the original backpressure algorithm. Simulation results show that the proposed algorithms have better delay performances in all scenarios we considered.
