Peer-to-peer computing consists of an open-ended network of distributed computational peers, where each peer shares data and services with a set of other peers, called its acquaintances. The peer-to-peer paradigm was initially popularized by file-sharing systems such as Napster and Gnutella, but its basic ideas and principles have now found their way into more critical and complex data-sharing applications like those for electronic medical records and scientific data. In such environments, data sharing poses new challenges mainly due to the lac ....etc

Enabling Data Hiding for Resource Sharing in Cloud Computing Environments Based on DNA Sequences




INTRODUCTION

In order to protect data through the unsecure networks
like the Internet, using various types of data protection is
necessary. With advent of Cloud Computing idea, a
common problem, confidentiality of data, was emerged . Thus, to solve the raised difficulty,
combining different ideas can help to achieve an acceptable

:heart:Multiprotocol Label Switching:heart:
In computer networking and telecommunications, Multi Protocol Label Switching (MPLS) is a data-carrying mechanism that belongs to the family of packet-switched networks. MPLS operates at an OSI Model layer that is generally considered to lie between traditional definitions of Layer 2 (Data Link Layer) and Layer 3 (Network Layer), and thus is often referred to as a Layer 2.5 protocol. It was designed to provide a unified data-carrying service for both circuit-based clients and p ....etc

Data Sharing Among Mobile Users

Abstract :

Applications that rely on replicated data have different requirements for how their data is managed. For example, some applications may require that updates propagate amongst replicas with tight time constraints, whereas other applications may be able to tolerate longer propagation delays. Some applications only require replicas to interoperate with a few centralized replicas for data synchronization purposes, while other applications need communication between arbitrary replicas. Similarly, th ....etc
