Simulation Modeling of Large-Scale Ad-Hoc Sensor Networks
In the scenario of a natural catastrophe or a terrorist attack, a large number of self-organizing, low-cost sensor devices can be deployed over the affected area. Each device equipped with its own power source, sensor, processing unit and low-power radio, can be imbued with the intelligence to seek out its neighbours and join in a wireless network spanning the geographic domain. The sensed quantities can then be forwarded to collections points, where the information is aggregated and presented to emergency response teams. The authors are developing a high-performance framework for the large-scale Simulation of Wireless Ad-hoc Networks (SWAN). The framework is comprised of inter-operating sub-models for terrain, dispersion of hazardous substance, radio propagation, and the actual source code of ad-hoc networking protocols.
