ME Projects

1. Physical and MAC Layer Implementation of IEEE 802.15.7 Standard in MATLAB

Visible light communication (VLC) is a new communication technology that is proposed to tackle the spectrum shortage. In VLC, information is transmitted through modulating the visible light spectrum (400-700nm) that is used for illumination. It has the potential to provide high-speed data communication up to 15 Gb/s with improved energy efficiency and communication security/privacy. Due to increasing interest of researcher in VLC communication, IEEE has introduced its VLC standard of IEEE 802.15.7. The standard defines the physical and MAC layer parameters for short-range optical wireless communication. It covers topics such as network topologies, collision avoidance, addressing, performance, quality indicators, dimming support, colored status indication, and stabilization. Matlab is a popular numerical and simulation tool among the scientific community. It has support available for communication channels, coding, and modulation schemes. IEEE 802.15.7 is using some of the existing physical and MAC layer schemes (CSMA/CA), which is already implemented in MATLAB. The project aims to develop a simulation tool based on the IEEE 80.2.15.7 standard, which helps the research community.

Objectives:
- To develop an open source MATLAB simulation tool for the research community
- Implementation of IEEE 802.15.7 Physical and MAC layer parameters in MATLAB

Student pre-requisites:
- Experience with MATLAB
- Good understanding of wireless communication concepts
- Good mathematical background
- Understanding of IEEE standards

2. Integration of MATLAB and NS3 for Visible Light Communication

Visible light communication (VLC) is a new paradigm that could revolutionize the future of wireless communication. In VLC, information is transmitted through modulating the visible light spectrum (400-700nm) that is used for illumination. The exponential improvement in the High-power light emitting diodes (LED) is an enabler for VLC communication. It has the potential to provide high-speed data communication up to 15 Gb/s with improved energy efficiency and communication security/privacy. Standardization efforts such as VLCA and IEEE 802.15.7 shows that VLC would augment existing wireless networks in coming years. It has applications in IoT, vehicular communication, hospitals, localization, toys, and traffic engineering.

Objectives:
- Integration of MATLAB with NS3 Simulator
- Simulating the available MATLAB models of channels and coding in NS3 Simulator
- IEEE 802.15.7 physical and MAC layer implementation in MATLAB and its integration with NS3.

Student pre-requisites:
- Experience with network simulation tool
- Experience with MATLAB
- Good understanding of wireless communication concepts
- Good mathematical background
