BTLive is a novel, unique, mesh/push-based peer-to-peer (P2P) live video streaming mechanism. Previous studies show that it achieves significantly lower streaming delays than other approaches but suffers from a high overhead, where peers receive up to 33% duplicate video chunks. Other P2P streaming mechanisms, most of which are either mesh/pull or tree/push-based, do not experience duplicates at such...
Video content makes up more than half of the world's Internet traffic, and this figure is expected to grow rapidly. New techniques that remove traffic redundancy have been shown to significantly improve network performance since many concurrent streams deliver the same video. These techniques employ smart routers that recognize duplicated video streams and merge them to reduce traffic redundancy....
A flow-aware approach of evaluating the probability of compromise in combined structure network is presented. Experimental and numerical examples have been used to analyze the influence on flow compromising of security parameters of network links and fragments. It is shown that the proposed approach gives more precise results of calculation the probability of flow compromise when using overlapping...
In order to rapidly response to users request in high-speed mobile environment, achieve efficient content distribution in content center network, this paper proposed a novel multipath routing transmission mechanism based on network coding (MRNC). By using network coding technology, users Interest packet is divided into multiple child interest packet, and the content is divide and random linear codes...
Low-power and Lossy Networks (LLNs) have been a key component in the Internet of Things (IoT) paradigm. Recently, a standardized algorithm, namely Trickle algorithm, is adopted for routing information maintenance in such networks. This algorithm is originally designed for disseminating code updates through a wireless sensor network. Thus, when it comes to routing maintenance in LLNs, Trickle suffers...
Designing a cost-effective network for data centers that can deliver sufficient bandwidth and provide high availability has drawn tremendous attentions recently. In this paper, we propose a novel server-centric network structure called RCube, which is energy efficient and can deploy a redundancy scheme to improve the availability of data centers. Moreover, RCube shares many good properties with BCube,...
Named Data Networking is a new data centric kind of communication network. This paper shows the study about NDN network and applies this architecture over Vehicular ad-hoc networks so that performance of network improves and communication becomes faster. At the end of simulation results are discussed in the form of packet delivery ratio, throughput, good put, routing overhead and various network parameters...
The Content-Centric Networking (CCN) concept is a significant approach of several future Internet research activities. CCN in Wireless Sensor Networks present a promised technique that may ensure data routing based on content. In this paper, we focus on the lifetime of the Content Object exchanged in the network and we explain the idea of its integration in CCN for WSNs to better highlight the relevance...
The built-in caching capability of future Named Data Networking (NDN) promises to enable effective content distribution at a global scale without requiring special infrastructure. The aim of this work is to design efficient caching schemes in NDN to achieve better performance at both the network layer and application layer. With the specific objective of minimizing the inter-ISP (Internet Service...
Logistics entities are interrelated to each other, any disruption or sudden unavailability of the entities may cause severe cascading disruption effects on the functioning of the entire logistics network. In analyze the cascading disruption effects, it is important to actively concern the normal logistics practices, rather than passively emphasize on learning from the past incidents. This paper proposes...
The purpose of this work is to promote an improvement of backbone networks in terms of availability and remote access. It especially focuses on network environments based on a hub and spoke topology. The significant findings indicate that data isolation, data encryption and encrypted dynamic routing information transmission are the main requirements for backbone network security. In addition, due...
NoC has redundant features, that is to say, there are multiple paths from the source node to destination node, these provided conditions for us to study fault-tolerant routing algorithm. This thesis proposes a new fault-tolerant algorithm by studying the existing fault-tolerant routing algorithm. Divide each node into edge nodes and internal nodes based on the network's position of 2D - Mesh topology...
This paper studies the fault management in mobile ad hoc networks. We focus on schemes which provide the robustness in MANETs: service restoration and service protection. Firstly, we propose an analytical comparison of service restoration, in terms of restoration time, at the routing layer (reactive and proactive protocols). Service restoration with reactive protocol is the most suitable in MANETs...
Coffee production stands crucial asset in growing the economy of varied countries. The serious impact to the coffee plantation is due to the pest named Coffee White Stem Borer (CWSB). CWSB once enters into coffee stem, it bores inside and does not reveal its existence till the plant completely collapses. Current manual methods to identify and reduce the damage to coffee plantation fail to arrest CWSB...
Internet infrastructure is highly distributed among different private and public sector entities. Although networks using Transmission Control Protocol (TCP) are highly resistant to failures — especially when multiple paths from sender to receiver exist - they have the potential to fail if a concentration of high-capacity routes between a particular sender and receiver become unavailable. The geographic...
With the rapid shift from end-to-end communications to content-based data retrieval, there are increasing interests in exploiting Content-centric Networks (CCN) to deliver data. As the special characteristics of CCN, in-network caching and naming-based routing make traditional TCP-like transmission control protocol unsuitable. Although there are some existing efforts on improving the congestion control...
Large-scale storage systems often face node failures that lead to data loss. Cooperative regeneration has been extensively studied to minimize the repair traffic of simultaneously reconstructing the lost data of multiple failed nodes. However, existing cooperative regeneration schemes assume that nodes are homogeneous. They do not consider how to minimize the general regenerating cost when taking...
The alluring benefits of Mobile Cloud Computing have attracted many mobile device users. The moving property of the mobile devices can serve as the boon to its user but curse for its developers. The moving devices cause the problems of the link faults, less available resources and unreliable dynamic networking conditions. The link failure of the nodes in the changing network decreases the performance...
Avionics implementation with less cables will clearly improve the efficiency of aircraft while reducing weight and maintenance costs. To fulfill these emerging needs, an innovative avionics communication architecture, based on Gigabit Full Duplex Ethernet ring, is proposed in this paper. To adapt this COTS technology to safety-critical avionics, an adequate tuning process of the communication protocol...
With the rapid growth of content-based network services, there is increasing interest in reducing the emissions associated with brown-energy consumption in Content Delivery Networks (CDNs). At the same time, content needs to be placed in safe Data Center (DC) locations, which are unlikely to be hit by disasters. Further risk reduction is achieved using content replication which provides inter-DC content...
