Currently, almost all network operators worldwide are upgrading their GSM networks in order to provide high speed mobile data to their subscribers. The ever increasing growth rate of data applications such as e-mail and the internet is confronting mobile network operators worldwide with the challenge to upgrade their networks to high bandwidth capable bit pipes in order to provide for all kinds of mobile data applications. High speed mobile data will combine two of today's most rapidly growing technologies, mobility and the internet.

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc

Adhoc networks find there application in the field of military tactical communications and various other emergency situations. Before we can efficiently use this type of network it is essential for us to understand the various control problems associated with adhoc networks. These include the power control problem. This problem infringes itself into the various layers of the OSI reference model. It basically affects the networking by affecting the battery life of the system. So the necessary solution is investigated over here, this solution bei ....etc

Power System Restoration (PSR) has been a subject of study for many years. In recent years many techniques were proposed to solve the limitations of predetermined restoration guidelines and procedures used by a majority of system operators to restore a system following the occurrence of a wide area disturbance.

This paper discusses limitations encountered in some currently used PSR techniques and a proposed improvement based on Artificial Neural Networks (ANNs). This proposed scheme has been tested on a 162-bus transmission system and compa ....etc

ABSTRACT
Location prediction serves to save capacity on the air interface of mobile radio networks. A selection of neural networks of the feed-forward and feedback type are examined to prove their suitability for this purpose. As first results preferable network structures, input vectors, learning parameters and the simulated prediction probabilities are presented. A comparison with conventional methods shows the advantages and disadvantages of the use of neural networks for motion prediction. The results show that t ....etc

In recent years, there has been a rapid increase in wireless network deployment and mobile device market penetration. With vigorous research that promises higher data rates, future wireless networks will likely become an integral part of the global communication infrastructure. Ultimately, wireless users will demand the same reliable service as today's wire-line telecommunications and data networks. However, there are some unique problems in cellular networks that challenge their service reliability.

In addition to problems int ....etc

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.

The military tactical and other security-sensitive operations are still the main applications of ad hoc networks, although there is a trend to adopt ad hoc networks for commercial uses due to their unique properties. One main challenge in design of these networks is their vulnerability to security attacks ....etc

A storage area network (SAN) is defined as a set of interconnected devices (for example, disks and tapes) and servers that are connected to a common communication and data transfer infrastructure such as Fibre Channel. The common communication and data transfer mechanism for a given deployment is commonly known as the storage fabric. The purpose of the SAN is to allow multiple servers access to a pool of storage in which any server can potentially access any storage unit. Clearly in this environment, management plays a large role ....etc

As electronic devices become smaller, lower in power requirements, and less expensive, we have to adorn our bodies with personal information and communication appliances. Such devices include cellular phones personal digital assistants (PDAs) pocket video games and pagers. Currently there is no method for these devices to share data. Networking these devices can reduce functional I/O redundancies and allow new services and conveniences.

The concept of Personal Area Networks (PANs) is presented to demonstrate how electronic devices on and ne ....etc

The communications capability of devices and continuous transparent information routes are indispensable components of future oriented automation concepts. Communication is increasing rapidly in industrial environment even at field level.In any industry the process can be realized through sensors and can be controlled through actuators. The process is monitored on the central control room by getting signals through a pair of wires from each field device in Distributed Control Systems (DCS). With advent in networking concept, the cos ....etc
