Introduction
Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different sets of physical and operational constraints; wide variations in transmission latency are particularly troublesome. The proposed Interplanetary Internet, which must encompass both terrestrial and interplanetary links, is an extreme case. An architecture based on a least common denominator protocol that can operate successfully and (where required) reliably in multiple disparate e ....etc

ABSTRACT
A mobile ad hoc network (MANET), sometimes called a mobile
mesh network, is a self-configuring network of mobile devices
connected by wireless links. The Ad hoc networks are a new
wireless networking paradigm for mobile hosts. Unlike traditional
mobile wireless networks, ad hoc networks do not rely on any
fixed infrastructure. Instead, hosts rely on each other to keep the
network connected. It represent complex distributed systems that
comprise wireless mobile nodes that can freely and dynamically
self-organize into ar ....etc

Seminar on Ad hoc networking


ABSTRACT

By definition, a mobile ad hoc network does not rely on any fixed infrastructure; instead, all networking functions (e.g., routing, mobility management, etc.) are performed by the nodes themselves in a self-organizing manner. For this reason, securing mobile ad hoc networks is challenging and, in some applications this requires a shift in paradigms with respect to the traditional security solutions for wireline networks. Meanwhile, we still rely on traditional cryptogr ....etc

Mobile Ad hoc Networking (MANET)



1. Introduction


With recent performance advancements in computer and wireless
communications technologies, advanced mobile wireless computing is
expected to see increasingly widespread use and application, much of
which will involve the use of the Internet Protocol (IP) suite. The
vision of mobile ad hoc networking is to support robust and efficient
operation in mobile wireless networks by incorpor ....etc

ABSTRACT
In the near future, a pervasive computing environment can be expected based on the recent progresses and advances in computing and communication technologies. Next generation of mobile communications will include both prestigious infrastructured wireless networks and novel infrastructureless mobile ad hoc networks (MANETs). A MANET is a collection of wireless nodes that can dynamically form a network to exchange informat ....etc

Bluetooth Ad Hoc Networking

Abstract :

Bluetooth is an open specification for short-range wireless communication and networking mainly intended to be a cable replacement between portable and/or fixed electronic devices. The problem concerns the assignment of the roles of master and slave to each node so that the resulting MANET is connected. In this Seminar we have introduce two novel protocols for forming connected scatternets. In both cases, the resulting topology is termed a bluetree. We also address the problem of determining an opt ....etc

Abstract

Opportunistic networks are one of the most interesting evolutions of MANETs. In opportunistic networks, mobile nodes are enabled to communicate with each other even if a route connecting them never exists. Furthermore, nodes are not supposed to possess or acquire any knowledge about the network topology, which is instead necessary in traditional MANET routing protocols. Routes are built dynamically, while messages are en route between the sender and the destination(s), and any possible node can opportunistically be used as ....etc

The Synchronous optical network, commonly known as SONET, is a standard for communicating digital information using lasers or light emitting diodes (LEDs) over optical fiber as defined by GR-253-CORE from Telcordia. It was developed to replace the PDH system for transporting large amounts of telephone and data traffic and to allow for interoperability between equipment from different vendors.

The more recent Synchronous Digital Hierarchy (SDH) standard developed by ITU (G.707 and its extension G.708) is built on experience in the development ....etc
