The Impact of Obstacle on the Performance of Vehicular Ad hoc Network

A recent dissertation by an MSc Computing (Computing Network Engineering) looked at Vehicular Ad Hoc Network simulation for reducing traffic congestion and how obstacles effect the communication performance in the network.

The Impact of Obstacle on the Performance of Vehicular Ad hoc Network

Recently, Vehicular Ad hoc network (VANeT) has gain popularity due to the increase in vehicle safety and reducing traffic jam in urban and highway environment. Wireless Access for Vehicular Environment (WAVE) which is part of Dedicated Short Range Communication (DSRC) protocol was developed to adapt to VANeT requirements to support vehicle communication and Intelligent Transport System (ITS). The dissertation focuses on simulating how obstacles affect the performance of VANeT communication. Communication takes place using Vehicle-to-vehicle (V2V) and Vehicle-toInfrastructure (V2I) architecture with emphasis on Line of Sight (LOS) and Non-line of Sight (NLOS) transmission by the measuring total number of successful and unsuccessful packets decoded. The simulation was implemented using open source Veins framework which runs on OMNeT++ engine, coupled with SUMO which provides a realistic microsimulation for vehicles. The research is limited to Northampton town centre, Avenue and Park Campus surroundings. The environments were implemented with low, medium and high vehicle density with message broadcast throughout the simulation run time. Results generated were evaluated and analysed. Final results suggest that LOS and NLOS transmission play a role on different circumstances with regard to VANeT architecture and application. Finally, this project is the continuation of interim report written earlier.

Social Analysis of Publications

The Computing staff's network of co-authors, at the University of Northampton, based on the University's  research repository NECTAR - on 12th November 2016. The data goes back to 2010.

The data was analysed using the software VOSviewer - free software for visualising networks. Differences in colours represents, the clusters of publications with those authors picked out by the software. The relative size of the circles is the relative number of publications listed; so for the two biggest circles/hubs it relates to 55 and 34 publications in this time period. Some relatively new authors, to the University but not to research, explains some of the 'islands' and the number of publications within it - it only reflects publications whilst at the University of Northampton.

To dig a little deeper, going to  look at the two biggest 'hubs' through their NECTAR records, so potentially going …

Computer lecturer’s research helps improve the next generation of technology

Taken from: A computing lecturer at the University of Northampton, who is researching into how the efficiency of our everyday devices, such as mobile phones, can be improved, has been awarded the best paper at two recent conferences. Dr Michael Opoku Agyeman has written several journal papers focusing on how the next generation of technology can meet the ever increasing demands from consumers. He was invited to present his work at the 19th Euromicro Conference on Digital System Design in Cyprus and the Institute of Electrical and Electronics Engineers’ 14th International Conference in Paris. Part of his research concentrates on whether several processing elements can be incorporated on a single chip, known as System-On-Chip, to improve the efficiency and speed of the computing systems that we use every day, from mobile phones to video-game consoles and even medical equipment…
