Performance Analysis of WebRTC-based Video Conferencing

Video Conferencing has been rapidly gaining attention and is becoming a more popular way to communicate due to better internet connectivity and increasing computation power. Because of this increase in demand, the dying out of proprietary plugins like Adobe Flash, and the need for easy and accessible video conferencing, a new browser technology...

Implementation of Bio-Informatics Applications on Various GPU Platforms

As of 2012, the world creates 2.5 quintillion bytes of data every day. Much of this data generated is what we refer to as Big Data. To explore how Big Data can create potential value and show the technical challenges accompanied with Big Data applications, we choose an application from bio-informatics: the Smith Waterman genetic database...

Performance Evaluation of Cloud Infrastructure using Complex Workloads

Infrastructure as a Service (IaaS) is a delivery model of cloud computing, which provides the ability to users to acquire and release resources according to their demand and pay according to their usage. Resources are provisioned from the cloud as Virtual Machines (VMs), many of which can be deployed on a single computing node, realizing a multi...

Performance and fairness enhancement in ZigBee networks

ZigBee is a robust wireless communication standard which is based on physical and MAC layer on IEEE 802.15.4. ZigBee is also critically limited by the low data rate standard when there are many source nodes in the network. How to fairly and efficiently access the network and delivery the packets should be considered as one of the crucial issues....

System performance analysis and fixed-point architecture of a gradient-based optical flow algorithm

Optical flow algorithms present a way for computers to estimate motion from the real world. Applications like cloud motion, surveillance and robot eyesight are examples of this. The focus of existing research is mainly on either fast, but poor solutions, or slow but good solutions. In this thesis an approach to improve performance through...

Performance Analysis of the Hybrid TDMA/CDMA Multiple Access Protocol for Mobile Multi-Media Communications

A novel hybrid TDMA/CDMA multiple access protocol is proposed that complies with the requirements for the future third-generation Universal Mobile Telecommunications System (UMTS). This protocol is capable of integrating a range of different types of services, like constant bitrate services (voice) and packet mode services. Its performance is...

CD-I over ATM: The effects of cell loss

The current design and implementation of the CD-i over ATM application will be described. A cell loss inducer has been designed and implemented, in order to measure the effects of cell loss on the CD-i over ATM application on a qualitative basis. Preliminary experiments after implementing part of the cell loss inducer revealed major problems...
