“…In [21] a fluid model is proposed to analyze P2P networks and it is used to calculate performance parameters such as the number of peers in steady state in the system, as well as the average time required to download a file; however, the proposed scenario in that work does not consider the specific features of VoD services. In [16][17][18] the fluid model was applied to a VoD, P2P network, where the shared video is split into windows in order to simplify the chunks interchange among peers. In this paper we also analyze a windows-based P2P network; but, in order to guarantee an adequate level of service, we additionally consider that the system is assisted by servers' bandwidth and that the size of the initial window is different from the remaining ones.…”

“…In order to guarantee an adequate service in terms of a QoE score, we propose a number of key modifications to the previously described window-based strategy. Specifically, unlike the works presented in [16][17][18], where windows were assumed to have the same size, here we propose that the size of window 0 can be different from the size of the remaining windows. The rationale behind this modification is to achieve a trade-off between the initial delay and the pauses duration.…”

“…However, BitTorrent can still be used for streaming VoD services by making relatively minor modifications. The window-based peer selection scheme described in [16][17][18] is an example of such modifications.…”

We describe a Peer-to-Peer (P2P) network that is designed to support Video on Demand (VoD) services. This network is based on a video-file sharing mechanism that classifies peers according to the window (segment of the file) that they are downloading. This classification easily allows identifying peers that are able to share windows among them, so one of our major contributions is the definition of a mechanism that could be implemented to efficiently distribute video content in future 5G networks. Considering that cooperation among peers can be insufficient to guarantee an appropriate system performance, we also propose that this network must be assisted by upload bandwidth from servers; since these resources represent an extra cost to the service provider, especially in mobile networks, we complement our work by defining a scheme that efficiently allocates them only to those peers that are in windows with resources scarcity (we called it prioritized windows distribution scheme). On the basis of a fluid model and a Markov chain, we also developed a methodology that allows us to select the system parameters values (e.g., windows sizes or minimum servers upload bandwidth) that satisfy a set of Quality of Experience (QoE) parameters.

“…But CAP method may lead to the closest-ahead peer overloading situation, without considering the overall system performance. Rivero-Angeles et al [12] proposed selecting neighbors according to their progress in the file download process relative to the progress of the requesting peers. Peers in the group of downloading the file at window i w download pieces from peers in any group downloading the file at window j w for i j  but this policy ignores the upload bandwidth and physical location of peers.…”

Abstract:In order to provide streaming media service with higher quality, a new data scheduling mechanism based on improved particle swarm optimization algorithm is proposed. This mechanism applies the idea of particle swarm optimization to peer selection of BitTorrent (BT) streaming system. First, improved particle swarm optimization (IPSO) algorithm is developed to overcome the shortcoming of falling easily into local optimum. Second, particle encoding and decoding are defined in the context of streaming media data scheduling, and fitness function based on the service ability of a peer is proposed. Third, IPSO-based neighbor peer selection (IPSO-NPS) algorithm is designed, in which the optimal solution of IPSO determines the set of peers providing data block resources. Simulation results show that IPSO algorithm enhances the convergence speed and accuracy, and the new data scheduling mechanism of IPSONPS reduces the startup delay of system, enhances the media playing continuity and reduces the network load.

ABSTRACT:Wireless sensor networks are composed by a big number of autonomous nodes surveying a certain environmental parameter, such as temperature, humidity or even mobile targets. In this work, we focus on mobile target detection in wide area systems such as tracking animals in a forest or vehicle detection in security missions. Specifically, a low energy consumption clustering protocol is proposed, analyzed and studied. To this end, two communication schemes, based on the well-known LEACH protocol are proposed. The performance of the system is studied by means of a mathematical model that describes the behavior of the network under the most relevant parameters such as coverage radius, transmission radius, and number of nodes inside the network. Additionally, the transmission probability in the cluster formation phase is studied under realistic considerations of a wireless channel, where signal detection errors occur due to interference and noise in the access channel. RESUMEN:Las redes inalámbricas de sensores están compuestas por un gran número de nodos autónomos que vigilan algún parámetro del ambiente de interés, como puede ser la temperatura, la humedad o incluso objetivos móviles. Este trabajo se enfoca en la detección de móviles en áreas amplias como puede ser la vigilancia de animales en un bosque o la detección de vehículos en misiones de seguridad. Específicamente, se propone, analiza y estudia un protocolo de agrupación de bajo consumo de energía. Para ello, se presentan dos esquemas de comunicaciones basados en el bien conocido protocolo LEACH. El desempeño del sistema se estudia por medio de un modelo matemático que describe el comportamiento de la red bajo los parámetros más relevantes, como son: radio de cobertura, radio de transmisión y número de nodos en la red. Adicionalmente, se estudia la probabilidad de transmisión en la fase de formación de grupos bajo consideraciones realistas de un canal inalámbrico, en donde la detección de la señal tiene errores debido a la interferencia y ruido en el canal de acceso.
