Master thesis in electrical engineering

Background

The success of 3G/UMTS and next generation wireless technologies depend on the users' satisfaction, affordability and its availability to provide services to communications, entertainments and other various applications in which the technology will be of great importance in telecommunication and ultra fast communication for end to end users[5][10][9].

Future wireless networks will be heterogeneous in nature and will rely on intelligent Network selection decision strategies to aid in QoS [6]. An heterogeneous wireless networks integrate different wireless network technologies, e.g. IEEE 802.16 (WMAN), WCDMA, CDMA, GPRS/EDGE,IEEE 802.15 (WPAN), IEEE 802.11 (WLAN),SATELLITE NETWORKS [2][1][10] , therefore practical mobility and quality of service solutions are of necessity in the existing 3G and the B3G wireless network.[2][3][4][6].

The next significant phase in strengthening the existing and the emerging wireless networks is the Quality of service (QoS) provisioning as mobile services (video and multimedia) are large proportion of activities taking place in the recent wireless technology evolution.[7][5]

A result more care about Quality of service measurement and verification is needed, which calls for the contribution of this thesis work in terms of evaluation of Quality of service parameters. These QoS parameters are the throughput, jitter, packet loss and delay which indicate more about the efficiency and the network reliability, e.t.c. The evaluation of this thesis work result will be done after using OPNET simulation tool OPNET to simulate our scenario.

Aims and objectives

The main aim of this thesis project is to Evaluate the quality of service in UMTS/3G wireless network and decide if it can to support the B3G/4G network:

Discussion about different QoS parameters/metrics for service application majorly voice and video communications in UMTS/3G.

Based on the result of QoS metrics existing for 3G/UMTS network we will discuss about the suitability for B3G/4G wireless networks.

Evaluation of different QoS parameters based on our simulations and analysis.

Draw our final conclusion

Research questions

How the QoS parameters of the existing 3G/UMTS wireless networks can supports voice and video transmission?

How can the quality of video/voice transmission be improved on 3G wireless network?

Is it needed to improve the existing QoS parameters for 4G/B3G communications?

Expected outcomes

A description of the UMTS/3G network framework and architecture
Model and graphs depicting the output realize from different QoS metric measurements, which is the basis of our evaluation.
Evaluation of our result, and recommendation of what should be added to improve the QoS to have a successful large transmission support on B3G network.

Research Methodology

We will search for information from the BTH library database, and we will read books and journals related to the thesis work.

We will ask for feedback from each other on our progress on the research work.

In our simulation we will design different scenarios for both voice and video conference and measure the performance of some parameters such as throughput, jitter, packet loss and delay as well as meet the goal to analysis the quality of video and voice in 3G/UMTS wireless networks.

We will also make thorough simulations till we get a best of convincing result

Risks

The major risks that might treat the realization and completion of the thesis work are

The Time span.

Availability of the suitable simulation tool

Dedication of the participating students.

We have planned to resolve these major risks as follows:

Effective utilization of every minute to maximize the time frame of the thesis work.

Early application and sourcing for simulation tools, even with the help of our supervisor.

Ensure and embrace perfect team work format and ensures both parties effective participation.
