The growth of data at an unprecedented rate poses challenge on its storage and analysis. To cope up with this, new machines are procured on a regular basis. On the other hand, a lot of computing resources in Institute labs, government offices etc. remain underutilized, since they are used for Internet and basic utilities. The aggregation of these underutilized resources can be more than handful to...
Using AS-level Internet topology maps to determine accurate AS-level paths is essential for network diagnosis, performance optimization, reliability improvement, resiliency enforcement and topology-aware application development. One significant drawback that we have observed in many studies is simplifying the AS-level topology map of the Internet to an undirected graph, and then using the hop distance...
The long-term vision of an Internet of Things (IoT) is approaching reality and leading hardware vendors expect shipment of 50 billion devices in the near future. Emerging Internet standards will enable this huge number of embedded machines to interconnect and cooperate—and raise the challenge of building suitable software environments that provide scalability, reliability, and security at an efficient...
Wireless Mesh Network (WMN) is an emerging and practical wireless solution for metropolitan area networks to provide community broadband Internet access services by organizing and configuring nodes in the network efficiently and dynamically. In this survey, the concept of wireless mesh network has been described briefly as an emerging technology to provide Internet in large areas. Accordingly, the...
High-resolution video is defining a new age of peer-assisted video streaming over the public Internet. Streaming over 1-Mbps videos in a scalable and global manner presents a challenging milestone. In this work, we examine the feasibility of 1-Mbps streaming through a global measurement study. In contrast to previous measurement studies that crawl commercial applications, we conduct fine-grain, controlled...
As the latest development of the distributed storage technology, Cloud storage is the product of the integration of distributed storage and virtual technologies. Cloud storage is a method that allows you to use storage facilities available on the Internet. Relative to the current Commercial cloud storage file systems, introducing P2P network of interest groups put forward the idea of a P2P model based...
Today's Internet is facing many problems which did not take into account in its initial design, such as routing scalability, mobility and security. No matter evolutional or revolutionary solutions that are proposed in recent years, a recognized promising direction is to separate customer network from core network and separate identification from location. In this paper, we sketch out an architecture...
In this paper we study a reliable downloading algorithm for BitTorrent-like systems, and attest it in mathematics. BitTorrent-like systems have become immensely popular peer-to-peer file distribution tools in the Internet in recent years. We analyze them in theory and point out some of their limitations especially in reliability, and propose an algorithm to resolve these problems by using the redundant...
We introduce a ??bulk data transfer?? (BDT) mechanism across multi-autonomous system (AS). The mechanism performance is limited by the positions of source or replica servers and by the inter/intra AS routing strategies. Therefore, a new mechanism is proposed to enable the source peer to create several virtual replica servers to transfer the data to the destination peer together. The mechanism works...
In recent years, sensors have become smaller, more affordable, and widely used. Also, Internet spreads all over the globe, and made possible transfer large data instantly. Thereby, large scale weather sensor networks have been constructible. In this kind of sensor network, we need to consider load balancing, network redundancy, and reliability of sensor data. Using P2P technology is one of the solutions...
Overlay networks have emerged as a means to enhance end-to-end application performance and availability. Network topology plays an important role in utilizing resources in peer-to-peer systems. Epidemic algorithms are potentially effective solutions for disseminating information in large scale and dynamic systems. P2P networks are popular for their dynamicity, but they are easy to deploy, robust and...
We propose a decentralized Peer-to-Peer (P2P) Video-on-Demand (VoD) system. The traditional data center architecture is eliminated and is replaced by a large set of distributed, dynamic and individually unreliable helpers. The system leverages the strength of numbers to effect reliable cooperative content distribution, removing the drawbacks of conventional data center architectures including complexity...
This paper reviews attitudes toward acceptance and usability of file sharing for music downloading in Russia. There is a significant issue with respect to the copyright law legislation and enforcement. Since infrastructure, market conditions, social and economical situations in developing countries are different from those of developed countries, we decided to apply a well establish theory to a new...
Today, peer-to-peer (P2P) systems are used as a promising platform to deploy new applications and services in the internet. There are much interest in emerging P2P overlay network because they provide a good substrate for creating large scale data sharing, content distribution and application-level multicast applications. Overlay networks also have following advantages: redundant storage, efficient...
We developed a peer-to-peer (P2P) based networking service and designed a P2P based social networking service method and apparatus capable of appropriately providing a social networking service under P2P environments. This paper proposed a method for easily providing a social networking service, which will be used as a principal service on the basis of a universal P2P platform irrelevant to application...
This paper presents a suite of reliability mechanisms for P2PSIP-based conference services. These mechanisms can be divided into two categories. One is backup mechanism, which is designed to elect backup conference provider in a distributed and dynamic manner among all the participants of conference. The other category contains handover and failover mechanisms, which are designed to maintain continuous...
A challenge of peer-to-peer (P2P) storage is to build reliable data storage from inherently unreliable P2P network, and to do so efficiently. In this paper, we investigate the use of adaptive erasure resilient code (ERC) which changes ERC fragment size according to the size of the file distributed. We show that the adaptive ERC may greatly improve the efficiency and reliability of P2P storage. A number...
Global computing uses Internet-connected PCs volunteered by their owners. These PCs are diverse, volatile, and error-prone. Sophisticated scheduling methods commonly applied in grid computing may not be sufficiently scalable and flexible for global computing environments. This paper shows that it is possible to classify global computing hosts based on simple metrics such as availability and reliability,...
We examine the performance of peer-to-peer (P2P) media streaming using multiple description coding (MDC) and compare it with that of a content delivery network (CDN). In both approaches, multiple servers simultaneously serve one requesting client with complementary descriptions. This approach improves reliability and decreases the data rate a server has to provide. We have implemented both approaches...
