This book was released on 2011 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emerging trends in computing have increasingly had a network-centric focus. Networked services offered through cloud computing paradigms have replaced applications that would traditionally run on local machines. In addition, the growing usage of applications such as social networking and platforms such as smartphones has resulted in greater need for ubiquitous network access. The consequent heightened demand for networked computing warrants efficient utilization of the limited network resources and more intelligent resource control algorithms, with a focus on providing an enhanced user experience. This thesis examines quality-of-service aware resource control for both wireless and wired networks. The first part of the thesis focuses on smartphones, which have become the de-facto mobile computing platform. A smartphone typically has access to multiple types of wireless networks, such as cellular networks and WiFi. Moreover, the functionality of smartphones can be expanded by installing applications. These two core characteristics of smartphones also reveal their most significant limitations: lower available bandwidth and limited computing power. Both of these limitations are addressed in this thesis. Available bandwidth on wireless networks fluctuates over time and is also shared among all users connecting to the same base station. In this work we present a dynamic bandwidth prediction model that makes short term predictions on the evolution of bandwidth. The model is dynamic and adjusts to the latest measurements provided by Zeus, a bandwidth measurement tool we designed and implemented on Nokia phones. The bandwidth predictions of our model are utilized in a novel rate control scheme, which we demonstrate to offer better performance than existing schemes. We next investigate the computing limitations of smartphones. A novel framework is considered, where computational tasks may be transferred to a central server and the results are fetched back at a later time. The central server has ample computing resources compared to the smartphones and the computing speedup outweighs the communication delays. The goal is to minimize the latency experienced by computational tasks, while judiciously utilizing the scarce memory resources available at the smartphone. Given the fluctuating nature of wireless bandwidth, there is a tradeoff between limited connectivity and congestion at the mobile. The second part of this thesis investigates resource control issues in wireline computing and more specifically in packet switches. Packet switches are essential parts of the Internet backbone and are also present in every data center. Modern data centers are severely constrained by their power consumption and power saving schemes would enable their further expansion. We propose novel power-aware scheduling algorithms for switches that offer significant power savings while sacrificing minimal performance. Finally, we examine a novel, scalable two-stage ingress memory switch architecture and we add backlog awareness to the scheduling algorithm to improve performance and fairness as perceived by the user.

Download or read book Software Defined Networking Based Resource Management and Quality of Service Support in Wireless Sensor Network Applications written by Babedi Betty Letswamotse and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve greater performance in computing networks, a setup of critical computing aspects that ensures efficient network operation, needs to be implemented. One of these computing aspects is, Quality of Service (QoS). Its main functionality is to manage traffic queues by means of prioritizing sensitive network traffic. QoS capable networking allows efficient control of traffic especially for network critical data. However, to achieve this in Wireless Sensor Networks (WSN) is a serious challenge, since these technologies have a lot of computing limitations. It is even difficult to manage networking resources with ease in these types of technologies, due to their communication, processing and memory limitations. Even though this is the case with WSNs, they have been largely used in monitoring/detection systems, and by this proving their application importance. Realizing efficient network control requires intelligent methods of network management, especially for sensitive network data. Different network types implement diverse methods to control and administer network traffic as well as effectively manage network resources. As with WSNs, communication traffic and network resource control are mostly performed depending on independently employed mechanisms to deal with networking events occurring on different levels. It is therefore challenging to realize efficient network performance with guaranteed QoS in WSNs, given their computing limitations. Software defined networking (SDN) is advocated as a potential paradigm to improve and evolve WSNs in terms of capacity and application. A means to apply SDN strategies to these compute-limited WSNs, formulates software defined wireless sensor networks (SDWSN). In this work, a resource-aware OpenFlow-based Active Network Management (OF-ANM) QoS scheme that uses SDN strategies is proposed and implemented to apply QoS requirements for managing traffic congestion in WSNs. This scheme uses SDN programmability strategies to apply network QoS requirements and perform traffic load balancing to ensure congestion control in SDWSN. Our experimental results show that the developed scheme is able to provide congestion avoidance within the network. It also allows opportunities to implement flexible QoS requirements based on the system s traffic state. Moreover, a QoS Path Selection and Resource-associating (Q-PSR) scheme for adaptive load balancing and intelligent resource control for optimal network performance is proposed and implemented. Our experimental results indicate better performance in terms of computation with load balancing and efficient resource alignment for different networking tasks when compared with other competing schemes.

Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, the Internet is the most commonly used medium for the exchange of data in di?erent forms. Presently, over 60 million machines have access to the Internet and to its resources. However, the Internet is also the largest distributed system o?ering di?erent computational services and possibilities not only for cluster computing. If the needs of modern mobile computing and multimedia systems are taken into account, it becomes clear that modern methods must ensure an e?ective development and management of the Internet allowing each user fast access to this huge resource space. The Innovative Internet Computing Systems workshop is organized by the Gesellschaft fur ̈ Informatik(GI) in Germany. It intends to be an open me- ing point for scientists dealing with di?erent aspects of this complex topic. In contrast to the Distributed Communities on the Web workshops, which can be 2 considered as the roots of I CS, special attention is given to fundamental - search works and the application of theoretical and formal results in practical implementations.

Download or read book Resource Allocation with Carrier Aggregation in Cellular Networks written by Haya Shajaiah and published by Springer. This book was released on 2017-07-05 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces an efficient resource management approach for future spectrum sharing systems. The book focuses on providing an optimal resource allocation framework based on carrier aggregation to allocate multiple carriers’ resources efficiently among mobile users. Furthermore, it provides an optimal traffic dependent pricing mechanism that could be used by network providers to charge mobile users for the allocated resources. The book provides different resource allocation with carrier aggregation solutions, for different spectrum sharing scenarios, and compares them. The provided solutions consider the diverse quality of experience requirement of multiple applications running on the user’s equipment since different applications require different application performance. In addition, the book addresses the resource allocation problem for spectrum sharing systems that require user discrimination when allocating the network resources.
