Academic OPNET Research and Educational Projects

General Information

The following provides brief information about some of the current research projects which use OPNET:

Title: Enhancement of LTE and WiMAX standards for Smart Grid communications

The concept of the Smart Grid has arisen as a result of deregulation in the electricity industry, environmental concerns and the advent of new technology such as distributed generation. It is now more important than ever to deploy advanced communications infrastructures in the transmission and distribution networks for the purposes of data acquisition (e.g. smart meter readings), monitoring, control and protection. This project addresses enhancements to LTE and WiMAX, which were designed for human communication, to efficiently and reliably transport data from typical Smart Grid traffic sources. In particular, new base station resource scheduling algorithms are being evaluated to optimise performance in a Smart Grid. This is facilitated using the extensible framework of the built in OPNET LTE and WiMAX models.

Title: Development of MAC and network layer protocols for a swarm of Autonomous

Underwater Vehicles (AUVs) for search and monitoring applications
The aim of this work is to develop MAC and network layer protocol for a swarm of Autonomous Underwater Vehicle (AUVs) for search and monitoring applications. Biomimicy of swarm behaviours is used to determine the requirements of the communication protocols and the acoustic physical layer, which is typically used in underwater communications, sets the limitations in terms of latency and bandwidths. Thus delay-tolerant time-critical protocols are needed for this mobile sensor network. An OPNET simulation model is being employed to model the acoustic physical layer and to develop the MAC and network layer protocols.

Title: Development of a VANET based communication architecture for future traffic management systems

Vehicular Ad hoc networks (VANETs) will be one of the key components of the future traffic management systems. Safety and user convenience, collision avoidance, accident minimization, improved traffic flow etc. are the key performance criteria of a road traffic management system. To develop a successful road traffic management system, an efficient information dissemination model is required which can ensure quick and reliable sharing of information between vehicles, and between vehicles and the infrastructure. In this project, we aim to develop an efficient information dissemination model using a VANET architecture which will enable reliable sharing of road traffic information among various entities. The project will develop an adaptive VANET architecture and protocol that can support various classes of traffic with different QoS requirements. An OPNET simulation model is being employed to evaluate various dissemination models and compare them against other models found in the literature.

Title: Wireless mesh network architecture for Smart Grid communications

The aim of this research project is to develop an IEEE 802.11s base mesh network to provide last mile connectivity to smart grid devices in a Field Area Network (FAN) or Neighborhood Area Network (NAN). The project aims at developing a low cost WLAN based mesh network that supports all QoS requirements of a FAN.

Title: Dual radio heterogeneous wireless mesh network architecture for microgrid connectivity

The aim of this research project is to develop a mesh network architecture for microgrid connectivity and control. The demand response management in a microgrid environment is different from grid feed systems. This project will develop an adaptive dual radio based mesh network architecture to support dynamic applications in a microgrid environment.

Title: LTE/LTE-A based heterogeneous network architecture

Several projects are currently underway to develop future heterogeneous network architectures to support a multiservice QoS architecture in the M2M communications domain. Some projects are also investigating development of energy optimised hetnet architectures for M2M communications.

ELEC3500 - Telecommunications Networks

OPNET package is used to support the laboratory of the telecommunications networks course. This course is offered to undergraduate students of Telecommunications Engineering, Computer Engineering, Electrical Engineering, Photonics and other engineering students. The OPNET package is used to study basic networking techniques such as statistical multiplexing techniques, queuing techniques, local area networking techniques, etc. Students use OPNET simulation models to study various aspects of above techniques.

ELEC4840 - Final Year Project

In this course undergraduate students undertake their research work. Some of the undergraduate students use the OPNET simulation package to develop their simulation models to study various engineering system. Some of the recent study involving the package includes performance analysis of Body Area Networks, performance analysis of Zigbee network, performance analysis of WiMAX and WLAN networks.
