TCP Performance in Wireless Mobile Multi-hop Ad Hoc Networks (Electronics/Telecom Project)

There are many issues that limit the performance of wireless mobile multi-hop ad hoc networks (MANETs). One of them is that TCP is not well adapted to networks where routes can change or disappear often. In this paper the behaviour of a standard TCP implementation is studied in situations typical for MANETs and compared to the behaviour of a partial […]

Dense Space-Division Multiplexed Transmission Systems Using Multi-Core and Multi-Mode Fiber

In this paper, we describe recent progress in space-division multiplexed (SDM) transmission, and our proposal and demonstration of dense space-division multiplexing (DSDM), which offers the possibility of ultra-high capacity SDM transmission systems with high spatial density and spatial channel count of over 30 per fiber. We introduce the SDM transmission matrix, which cross indexes the various types of multi-core multi-mode […]

Load Management for a Telecom Charging System (Computer/Electronics Project)

There are a huge number of customers using Ericsson’s prepaid telecom charging system. This means that even the smallest optimization done in its management of load results in a big win when considering time and CPU usage. Ericsson wishes therefore to learn about how the load management can be improved considering speed, i.e. faster response to load changes. In this […]

Evaluation of Storage Area Network (SAN) Security and Performance

Due to growing the number of Information Technology (IT) users all around the world, consequently the amount of data that needs to be stored is increasing day by day. Single attached disks and old storage technologies cannot manage the storing these amounts of data. Storage Area Network (SAN) is a distributed storage technology to manage the data from several nodes […]

Design and Implementation of the MMS Portal (Electronics/Computer Project)

MMS-enabled terminals on the market today are very complicated to use. It takes several steps to create a multi-slide MMS-message with images and text. This discourages users from using it. To increase usage of MMS, several companies provide web-based or stand-alone programs that allow users to create and send MMS-messages from a regular computer. However these editors have many limitations […]

Speech Interface for a Mobile Audio Application (Electronics/Computer Project)

Today almost everyone owns a mobile phone, adults along with teenagers and kids. Even laptops and other wearable devices such as personal digital assistants (PDA’s) are become more common. We want constant connectivity to networks and the Internet, which in turn makes us more and more available. Context-awareness will play a bigger role for these devices in the future. Aware […]

Boundary-scan in the ACTA Standard (Computer Project)

Larger systems today, like telephone and optical switches, are usually based on a multi-board architecture where a set of printed-circuit boards are connected to a back-plane board. These systems are also equipped with Boundary-Scan to enable testing, however, the back-plane in a multi-board system has a limited wiring capability, which makes the additional back-plane Boundary-Scan wiring highly costly. The problem […]

Construction of Provisioning System for IP-Telephony Boxes

The point of this project is to cover a gap in today’s supply of provisioning systems for VoIP endpoint devices. Today the norm is that every manufacturer of endpoints builds their own system to provision their endpoints, but most operators use a vast verity of products to meet their customers’ needs. This system is based on open source software to […]

SIM Structure, File Structure & Communication Protocols of Mobile Phones (Electronics Project)

A subscriber identity module or SIM is a smart card that is designed to fit into mobile phone. It provides the identification of a user to a network, allowing him or her to access such services as telephony, email, internet and text messaging. The SIM card contains a microcomputer as well as a certain amount of memory to process commands […]
