Exploring the benefits of multipath TCP In wireless networks

The revolution of the information society has created a completely new situation in the telecommunications markets. As the average user data demands in today's society grow bigger, since users nowadays are demanding a faster, wider and more reliable communication service from the operators so they can watch more videos, listen to more music or access the Internet in general with a better quality, a lower latency and seamlessly to the network access they are using, the network operators face the challenge to fit this demands into their existing networks. This has forced the operators to think in terms of how optimal they are on providing their services if they want to fulfil the customer requirements in this new environment. At the same time we need to keep in mind that simultaneously to this new user's habits smartphones revolution has created, it has also made it possible to have accessible communication devices which have the necessary hardware and horsepower to keep different network interfaces up, and so it has become a common thing to reach the Internet via different kind of networks along the day. Even more it has enabled a rich communications environment where different connection possibilities are available to the user at the same time. In this context, the idea of multipath communication emerges. The idea of taking advantage of a dense wireless communication offer through the use of multipath (sending and receiving information through different network interfaces simultaneously) looks promising to overcome a situation where user's communications services demand grows and at the same time the mobile network load becomes stronger. The newfangled protocol Multipath TCP (MPTCP) is a technology which is enabling in practice this king of multipath communication, and it is the focus of this project to dig into possible benefits the protocol may bring to the table by defining a set of use cases, test-bed implementations and experiments with MPTCP which we present and analyse in this document.La revolución de la sociedad de la información ha creado una situación que es completamente nueva en los mercados de telecomunicaciones. A medida que el usuario medio aumenta su demanda de datos, ya que hoy en día los hábitos de estos pasan por conexiones más rápidas y fiables que les permitan reproducir contenido (video, música, páginas web) con mejor calidad, menor latencia y transparentemente a la red que estén utilizando, los operadores de red afrontan nuevos retos a la hora de encajar estas expectativas del usuario dentro de las posibilidades que ofrece la red. Esto está forzando a los operadores a buscar una manera más óptima de gestionar el tráfico de sus clientes para así poder satisfacer la demanda de unos servicios de mayor calidad que estos realizan. Al mismo tiempo hay que tener en mente que, de la misma manera que el impacto que esta esta revolución de los smartphones ha tenido en los hábitos de consumo del usuario ha creado nuevos y complejos problemas, también ha hecho posible que existan dispositivos económicamente accesibles para el público con el hardware y la capacidad de procesamiento necesarias para incorporar múltiples adaptadores de red, y esto a su vez ha llevado a al escenario actual en el que comúnmente coexisten en el mismo lugar diferentes posibilidades para conectarse a internet (típicamente Wi-Fi y conexión móvil, pero también podríamos nombrar tecnologías como el Bluetooth o la clásica conexión de Ethernet en ordenadores portátiles) Es en este contexto en el que surge la idea de la comunicación multi-trayecto. La idea de aprovechar un entorno con una densa pero heterogénea oferta de conexión a través del uso del multi-trayecto (enviar y recibir información a través de múltiples interfaces de red simultáneamente) aparece como una posibilidad prometedora para los operadores para mejorar la experiencia del usuario al mismo tiempo que se gestiona el tráfico en la red de una manera más eficiente. El protocolo experimental Multipath TCP es una extensión del TCP clásico que hace posible este uso simultáneo de múltiples interfaces para la comunicación, y es objetivo de este proyecto diseñar, implementar y testear el protocolo en diferentes casos de uso en los que el multi-trayecto ofrece, a priori, algunas ventajas. En las siguientes páginas explicaremos que casos de uso hemos elegido para probar el protocolo y por qué, cómo hemos diseñado e implementado los bancos de pruebas y que resultados hemos obtenido en nuestro experimentos sobre el rendimiento del protocolo, realizando al mismo tiempo un análisis crítico de los resultados de los resultados.Ingeniería de Telecomunicació

Traffic engineering multi-layer optimization for wireless mesh network transmission a campus network routing protocol transmission performance inhancement

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityThe wireless mesh network is a potential network for the future due to its excellent inherent characteristic for dynamic self-healing, self-configuration and self-organization. It also has the advantage of easy interoperability networking and the ability to form multi-linked ad-hoc networks. It has a decentralized topology, is cheap and highly scalable. Furthermore, its ease in deployment and easy maintenance are other inherent networking qualities. These aforementioned qualities of the wireless mesh network bring advantages to transmission capability of heterogeneous networks. However, transmissions in wireless mesh network create comparative performance based challenges such as congestion, load-balancing, scalability over increasing networks and coverage capacity. Consequently, these challenges and problems in the routing and switching of packets in the wireless mesh network routing protocols led to a proposal on the resolution of these failures with a combination algorithm and a management based security for the network and its transmitted packets. There are equally contentious services like reliability of the network and quality of service for real-time multimedia traffic flows with other challenges such as path computation and selection in the wireless mesh network. This thesis is therefore a cumulative proposal to the resolution of the outlined challenges and open research areas posed by using wireless mesh network routing protocol. It advances the resolution of these challenges in the mesh environment using a hybrid optimization – traffic engineering, to increase the effectiveness and the reliability of the network. It also proffers a cumulative resolution of the diverse contributions on wireless mesh network routing protocol and transmission. Adaptation and optimization are carried out on the wireless mesh network designed network using traffic engineering mechanism and technique. The research examines the patterns of mesh packet transmission and evaluates the challenges and failures in the mesh network packet transmission. It develops a solution based algorithm for resolutions and proposes the traffic engineering based solution.. These resultant performances and analysis are usually tested and compared over wireless mesh IEEE802.11n or other older proposed documented solution. This thesis used a carefully designed campus mesh network to show a comparative evaluation of an optimal performance of the mesh nodes and routers over a normal IEE802.11n based wireless domain network to show differentiation by optimization using the created algorithms. Furthermore, the indexes of performance being the metric are used to measure the utility and the reliability, including capacity and throughput at the destination during traffic engineered transmission. In addition, the security of these transmitted data and packets are optimized under a traffic engineered technique. Finally, this thesis offers an understanding to the security contribution using traffic engineering resolution to create a management algorithm for processing and computation of the wireless mesh networks security needs. The results of this thesis confirmed, completed and extended the existing predictions with real measurement

Towards a power consumption estimation model for routers over TCP and UDP protocols

Due to the growing development in the information and communication technology (ICT) industry, the usage of routers has increased rapidly. Meanwhile, these devices that are produced and developed today consume a definite amount of power, Furthermore, with limited focus on power estimation techniques and the increased demands of networking devices, it led to an increase of the vitality consumption as a result. While new high capacity router components are installed, energy intake in system elements will be rising due to the higher capability network consuming larger component of the vitality. This study considers providing estimating power model in different traffic settings over TCP and UDP protocols, this study is mainly concerned about the transport protocols power consumption. Isolating the power consuming components within an electronic system is a very precise process that requires deep understanding of the role of each component within the system and a thorough study of the component datasheet. The study started by simulating the protocols mechanism then followed by protoclos power measurements, a simple simulation has been provided for Xilinx Virtex-5, it is very complicated to simulate the whole system due to the need of an external devices, so the simulation focused on wavelengths, frequencies and traffic types. This study found that the estimated power stokes was high when the 1480nm, 1580nm, and 1750nm power source increase. while there were differrence in the consumed power while transiting different types of traffic such as CBR and HTTP through UDP and TCP. The effect of different frequencies has been noticed also while applying different frequencies to the protocols. So it is believed that this study may enhance the power scenarios in the network and routers throug applying different techniques to UDP and TC

On Boosting Integrated WLAN & ZigBee Network Performance via Load Balancing

Network traffic and overload are constantly increasing. This situation leads to congestion and packet losses at bottlenecks and across the different parts and devices of the network. Luckily, network technologies and techniques are developing rapidly. This paper is dedicated to applying and testing the impact of load balancing mechanisms on network performance. Two networking scenarios are considered: server on-premise and server on cloud . The research takes place in a vast scale network where two of the most popular technologies are spotted in an integrated multiprotocol scenario of Wireless Area networks (WLAN) with the Internet of Things (IoT) ZigBee. Previous studies were concerned by the challenges present due to the very different natures of IoT ZigBee and WLAN networks. This paper presents a better quality of service (QoS) by applying load balancing to these integrated scenarios. Not just that, it also introduces an even better Qos by deploying the rapidly growing popular technology of cloud computing to the same scenario of integrated networks with load balancing. By applying the same data rates with the same timers and networking parameters, network performance is measured and compared to show the difference between previous work without load balancing, and this papers work after deploying load balancing. The research shows whether load balancing has a positive or a negative effect on network performance or does not affect some cases. The network performance parameters under consideration are traffic dropped; traffic received, delay and throughput. Load balancing is tested regarding two different server positions
