Simulating and Modelling Wireless Sensor Networks
Simulation is heavily used in WSN research, but results are only as realistic as the models that they are built around. To ensure a close correlation between simulation and practical results, this research has developed communication, sensing, energy and timing models. WSNsim (a simulator for WSNs) has been developed as a model-centric simulator built around a structured ‘unified’ stack for communications, energy management and intelligent sensing.
WSNsim: A Simulator for WSNs
WSNsim (Wireless Sensor Network Simulator) was developed to debug, evaluate and improve algorithms developed at the University. WSNsim is an in-house object orientated discrete-event simulator for WSNs, developed using Microsoft Visual Studio .net 2005 (due to limited support and documentation, it is not currently available as open-source).

Environmental and Physical Modelling
To support WSNsim, a range of environmental and physical models were investigated, encompassing communication, energy, sensing and timing.
