Performance Measuring Tool

In order to collect the result, the use of performance measuring tools is important. Several performance measuring tools are available and widely used to measure the performance of different network and different 
data.

Wireles Monitoring

Wireles Monitoring is a diagnostic tool that falls under the category of WiFi Scanners or 802.11 Network Discovery Tools. A discovery tool reports the Service Set Identifier (SSID) for each wireless network it detects, along with the channel used by the access point (AP) servicing that network.

CommView VoIP Analyzer

CommView VoIP Analyzer has been chosen because it includes a VoIP analysis module that is suited for real-time capturing and analyzing VoIP events, such as call flow, signaling sessions, registrations, media streams, errors, etc. By visualizing this data and assessing voice quality, this tool helps in boosting productivity in debugging VoIP networks, software, and hardware

Week 4

The following explain the details of the system of server open system and client. 

 Client Server Architecture

The network consists of a server open system, a switch, an access point and several clients. The server will act as platform for client to direct calls from one end point or client to another end point or client. The switch is used to allow several network devices such as the access point and the server to communicate together. The access point will provide wireless connection for the end points to communicate to each other via the VoIP server. The client terminals are the end point of VoIP systems producing voice traffic on the network.

VoIP Server Application

There are several options to choose. PC-to-Phone, Phone-to-Phone, and PC-to-PC call. For this purpose of study, PC-to-PC calls are being used. VoIP with a computer can be used either using a headset with built in microphone, or computer speakers and microphone.The VoIP client application that has been chosen in this study is Skype and Yahoo Messenger. This is because Skype and Yahoo Messenger builds innovative SIP based softphones

Week 3

This week I search some of the Hardware and Software in implementing VoIP system *it important

Week 2

Final Year Project 2

Assalamualaikum, I continue to update some of the progress project for my Final Year Project 2 because of my previous semester, I already successfully finished my Final Year Project 1 assessment within 14 weeks. So, by  this semester January 2013 I must to continue my Final Year Project 2 assessment for complete my final year project. This semester assessment is more challenging to achieve my target to get the result. For this semester I need to make more research and analysis to the result for my project.

WEEK 12

RESEARCH PROGRESS

WEEK 11

Presentation week. On this week we are needed to present about our Final Year Project

By internet research and guideline of the RSP website, I have managed to complete this presentation slide on time. Before the presentation, many things that need to be in focus, example :

1. Introduction
2. Literature Review
3. Problem Statement
4. Research Objective
5. Methodology
6. Block Diagram
7. Project Timeline
8. Project Budget
9. Conclusion
10. Reference

With help from advisor and research from internet, I managed to complete this presentation slide.

WEEK 10

FACTOR EFFECT OF VOICE QUALITY

Delay is caused when packets of data / voice take more time than expected to reach their destination. This causes some disruption in the voice quality. However, if it is dealt with properly, its effects can be minimized . 
Delay mainly comes from three components :

1.  delay caused by voice codec algorithms 
2.  delay caused by queuing algorithms of communications equipment
3.  variable delay caused by various factors(i.e. network conditions, VoIP equipments, weathers etc).

It is very important to minimise the voice traffic delay. Thus, a codec algorithm and queuing algorithm needs to be carefully considered. High QoS should be assured by control delay so that one-way communication delay should be less than 150ms. (ITU states that one-way, end-to-end telephony applications should have less than 150ms delay in echo-free environments to ensure user satisfaction). Although traditionally think the end-to-end delay of 150 ms was considered as acceptable for most applications.
However, in reference [James, 2004], the authors state that a delay of up to 200ms is considered as acceptable. Moreover, a one way end-to-end delay between 150ms to 400ms is considered as acceptable for planning purposes. In this study, 200ms will be considered as the maximum acceptable one way end-to-end delay, high end-to-end delay can cause bad voice quality perceived by the end user.
