TRANSFERENCIA O DISTRIBUCIÓN DE ARCHIVOS ENTRE IGUALES (peer-to-peer) Características, Protocolos, Software, Luis Villalta Márquez Configuración Peer-to-peer Una red peer-to-peer, red de pares, red entre iguales, red entre pares o red punto a punto (P2P, por sus siglas en inglés) es una red de computadoras en la que todos o algunos aspectos funcionan sin clientes ni servidores fijos, sino una serie de nodos que se comportan como iguales entre sí. Es decir, actúan simultáneamente como clientes y servidores respecto a los demás nodos de la red. Las redes P2P permiten el intercambio directo de información, en cualquier formato, entre los ordenadores interconectados. Peer-to-peer Normalmente este tipo de redes se implementan como redes superpuestas construidas en la capa de aplicación de redes públicas como Internet. El hecho de que sirvan para compartir e intercambiar información de forma directa entre dos o más usuarios ha propiciado que parte de los usuarios lo utilicen para intercambiar archivos cuyo contenido está sujeto a las leyes de copyright, lo que ha generado una gran polémica entre defensores y detractores de estos sistemas. Las redes peer-to-peer aprovechan, administran y optimizan el uso del ancho de banda de los demás usuarios de la red por medio de la conectividad entre los mismos, y obtienen así más rendimiento en las conexiones y transferencias que con algunos métodos centralizados convencionales, donde una cantidad relativamente pequeña de servidores provee el total del ancho de banda y recursos compartidos para un servicio o aplicación. Peer-to-peer Dichas redes son útiles para diversos propósitos. -

Fresh Apps: an Empirical Study of Frequently-Updated Mobile Apps in the Google Play Store
Empir Software Eng DOI 10.1007/s10664-015-9388-2 Fresh apps: an empirical study of frequently-updated mobile apps in the Google play store Stuart McIlroy1 · Nasir Ali2 · Ahmed E. Hassan1 © Springer Science+Business Media New York 2015 Abstract Mobile app stores provide a unique platform for developers to rapidly deploy new updates of their apps. We studied the frequency of updates of 10,713 mobile apps (the top free 400 apps at the start of 2014 in each of the 30 categories in the Google Play store). We find that a small subset of these apps (98 apps representing ˜1 % of the studied apps) are updated at a very frequent rate — more than one update per week and 14 % of the studied apps are updated on a bi-weekly basis (or more frequently). We observed that 45 % of the frequently-updated apps do not provide the users with any information about the rationale for the new updates and updates exhibit a median growth in size of 6 %. This paper provides information regarding the update strategies employed by the top mobile apps. The results of our study show that 1) developers should not shy away from updating their apps very frequently, however the frequency varies across store categories. 2) Developers do not need to be too concerned about detailing the content of new updates. It appears that users are not too concerned about such information. 3) Users highly rank frequently-updated apps instead of being annoyed about the high update frequency.

Tech student, Dept of C.S.E, K L University, Vaddeswaram, Vijayawada, India Assistant Professor, Dept of C.S.E, K L University, Vaddeswaram, Vijayawada, India, Abstract: The peer-to-peer network is the one of the traditional client server networking model. The file sharing on mobile devices is not easily achieved to the user for limited bandwidth and high cost. The irregular disconnection and IP address changes occur due to network migration. We holds the short range networking technologies as Bluetooth with no cost to the user and it is sufficiently fast to make file transfer very practical. A peer-to-peer model that permits efficient file sharing between mobile smartphones over a low-cost transport. Our paper results that peer-to-peer file transfer between todays mobile devices are practical. But the server limits must be applied on the transfers. These are unique to the mobile device environment. The upload-over- download ratio should be relatively low, due to higher current drain on transmit. Where the target file system is very slow then the larger file segments “Direct Memory Access” (DMA) mode can be utilized as different to “Program Input Output” (PIO) mode. The use of UDP for content sharing is more ideal than the use of OBEX. We will overcome some of the barriers to acceptance through our design approach. -
Arxiv:1908.10237V1 [Cs.NI] 27 Aug 2019 Network Node to Network Node in a Store-Carry-Forward Manner
DTN7: An Open-Source Disruption-tolerant Networking Implementation of Bundle Protocol 7 Alvar Penning1, Lars Baumgärtner3, Jonas Höchst1;2, Artur Sterz1;2, Mira Mezini3, and Bernd Freisleben1;2 1 Dept. of Math. & Computer Science, Philipps-Universität Marburg, Germany {penning, hoechst, sterz, freisleb}@informatik.uni-marburg.de 2 Dept. of Electr. Engineering & Information Technology, TU Darmstadt, Germany {jonas.hoechst, artur.sterz}@maki.tu-darmstadt.de 3 Dept. of Computer Science, TU Darmstadt, Germany {baumgaertner, mezini}@cs.tu-darmstadt.de Abstract. In disruption-tolerant networking (DTN), data is transmit- ted in a store-carry-forward fashion from network node to network node. In this paper, we present an open source DTN implementation, called DTN7, of the recently released Bundle Protocol Version 7 (draft version 13). DTN7 is written in Go and provides features like memory safety and concurrent execution. With its modular design and interchangeable com- ponents, DTN7 facilitates DTN research and application development. Furthermore, we present results of a comparative experimental evalu- ation of DTN7 and other DTN systems including Serval, IBR-DTN, and Forban. Our results indicate that DTN7 is a flexible and efficient open-source multi-platform implementation of the most recent Bundle Protocol Version 7. Keywords: delay-tolerant networking · disruption-tolerant networking 1 Introduction Delay- or disruption-tolerant networking (DTN) is useful in situations where a reliable connection to a communication infrastructure cannot be established, e.g., during environmental monitoring in remote areas, if telecommunication networks are destroyed as a result of natural or man-made disasters, or if access is blocked due to political censorship. In DTN, messages are transmitted hop-to-hop from arXiv:1908.10237v1 [cs.NI] 27 Aug 2019 network node to network node in a store-carry-forward manner. -
Share, Collaborate, Exploit ~ Defining Mobile Web 2.0
WHITEPAPER Share, Collaborate, Exploit ~ Defining Mobile Web 2.0 This whitepaper is an extract from: Mobile Web 2.0 Leveraging ‘Location, IM, Social Web & Search’ 2008-2013 . information you can do business with Share, Collaborate, Exploit ~ Defining Mobile Web 2.0 Share, Collaborate, Exploit ~ Defining Mobile Web 2.0 Introduction The mercurial rise of social networking sites and user-generated content has rekindled users’ interest in accessing Web-based services on the move. That the mobile phone is an inherently personal device which is not only with us most of the time, but also contains a huge amount of personal data (contact lists of names and phone numbers, stored messages and emails etc.) makes it a logical extension for the social network and the host of other collaborative Web 2.0 applications gaining traction. Perhaps the major factors driving the shift in how the Internet operates – whether fixed or mobile – are those of user interaction and enhancement. The Web is no longer simply an online resource of information to be consulted, searched and acted upon. It has become a network of social communities and information databases that are constantly growing and improving as they continue to harness the collective intelligence of users. It could therefore be argued that whereas Web 1.0 served essentially as a broadcast medium (i.e. of information/knowledge) ‘Web 2.0’ takes the form of a platform whereby the creator of content, has become the focus. Defining Mobile Web 2.0 Difficulty in establishing a firm and accepted definition, plus the fact that many of Web 2.0’s core concepts cannot be replicated directly within the cellular environment, is paralleled in a similar debate on what exactly denotes Mobile Web 2.0.
