Introduction

The Internet itself, with its many protocols and supported applications, is becoming the reference point for the multi-service network infrastructure of tomorrow. The research community and the networking industry are working at a phenomenal rate to design and deploy the technologies, protocols, networks, and services that will make that goal a reality.
 

Voice Over Internet Protocol (VoIP)

VoIP services become increasingly important and offer a great opportunity to Internet Service Providers (ISPs) in generating revenue. At the same time it raises many technical challenges in providing high-quality services, such as delay constraint, interoperability and reliability.

The objective of this research is to explore issues related to the integration of voice and data networks and come up with solution that can be implemented in current communications networks.

Network Security

In this project we will examine various Distributed Denial of Service (DDoS) attacks on wireless network, and develop a framework to test and evaluate the effectiveness of different defensive techniques against those attacks. A range of research relates to vulnerability assessment and security of a network will also be conducted in this project.

Wireless Sensor Network

In this project we will analyse the performance of energy efficient protocols (including both MAC and routing protocols) for wireless sensor network. Questions related to target tracking, data collection and protocol design will also be investigated.

Performance Evaluation of 802.11 MAC protocol in wireless networks

Wireless local area networks (WLANs) are rapidly being deployed to provide users with network connectivity without being tethered off of a wire network. In WLANS the IEEE 802.11 Medium Access Control (MAC) protocol is widely used to share the wireless medium between users. The performance of the wireless network, as well as the quality of service (QoS) offered in WLANs depend heavily on the mechanism of the 802.11 MAC protocol.

In this project we will develop an analytical model for the 802.11 MAC protocol which can be used in finding the optimal parameter setting for 802.11 MAC protocol and to improve the overall network performance.
