This paper deals with multicasting in an internetwork with mobile hosts, particularly with regard to Mobile-IP [11] and Distance Vector Multicast Routing (DVMRP) [10, 9] protocols. When the source of a multicast datagram is a mobile host (MH), the datagram may not reach all group members to which the datagram is addressed, including other mobile hosts. When the source is a static host and the m...

Graphical notations have been widely accepted as an expressive and intuitive working tool for system specification and design. This paper outlines a declarative approach based on (hyper-)graphs and graph synchronization to deal with the modeling of Wide Area Network applications. This paper aims at contributing to the understanding of crucial issues involved in the specification and design of W...

The purpose of this thesis is to discuss issues of design, implementation and evaluation of a protocols architecture that can effectively support the interoperation and cooperation of separately administered Content Delivery Networks (CDNs). In general, a CDN can be thought of as an infrastructure that provides scalable content delivery from content providers to content consumers: specifically,...

In Social Internetworking analysis, bridge users play a key role when information crossing among different Online Social Networks (OSNs) is investigated. Unfortunately, not always users make explicit that they are bridges by specifying the so-called me edges (i.e., those edges connecting the accounts of the same user in distinct OSNs). Thus, discovering hidden me edges is an important problem t...

abstract: A base B of a space X is called an OIF base when every element of B is a subset of only a finite number of other elements of B. We will explore the fundamental properties of spaces having such bases. In particular, we will show that in T2 spaces, strong OIF bases are the same as uniform bases, and that in T3 spaces where all subspaces have OIF bases, compactness, countable compactness...

The Content Delivery Networks (CDNs) federation, also named Content Distribution Internetwork (CDI) has been proposed by the CDI IETF Working Group, but currently there are not running examples. In this position paper we analyses the issues concerning this new research area and propose a possible architecture for a CDI.

The seamless integrated communication has a vital role in pervasive communication. It has implemented on next generation networking. There is various integration issues: coupling, decoupling, mobility, IP etc. In this paper we propose an efficient protocol for the hybrid network and it covers the basic terminology as: syntax, semantic and timing properties and narrow the dilemma of above issues...

This report documents the program and the outcomes of Dagstuhl Seminar 13131 “Future Internet”. At the seminar, about 40 invited researchers from academia and industry discussed the promises, approaches, and open challenges of the Future Internet. This report gives a general overview of the presentations and outcomes of discussions of the seminar. Seminar 24.–27. March, 2013 – www.dagstuhl.de/1...

We discuss two common architectures intended to support the internetworking of wireless networks and the Internet. The \proxy architecture" uses a TCP gateway to provide a straightforward and easy solution. On the other hand, the \end-to-end architecture" implies more design issues but is deemed to provide a more elegant solution in the long-term. The advantages and drawbacks of both approaches...
