Simulation framework for wireless sensor networks | Knud Martin Hansen
| | Abstract | With the development of the MEMS technology and of wireless networking, the sensor network area has been an active field of research in the last five years. Sensor network propose a new approach to monitoring applications and provide high resolution observations of the environment. The main constraint of the sensor networks is energy as the nodes are powered with non renewable batteries, and numerous techniques and design strategies have been studied to optimize power consumption for these networks. The design space for hardware and software is very large, and the consequences of design decisions may be difficult to foresee in such large and dynamic systems. In order to help the sensor network designer in his task, a simulation framework was developed. It defines a structure representing sensor nodes and their interconnection within the network. The framework models the major aspects of sensor networks such as battery lifetime, node mobility, radio communications and it also represents the behavior of the environment. The implementation of the framework focuses on modularity, allowing to experiment the consequences of using various techniques and architectures. Examples inspired on common sensor network architectures are presented, and the ability of the framework to cover the design space are discussed. Scalability being a main issue on sensor networks, the performance of the simulation is measured. | | Type | Master's thesis [Academic thesis] | | Year | 2004 | | Publisher | Informatics and Mathematical Modelling, Technical University of Denmark, DTU | | Address | Richard Petersens Plads, Building 321, DK-2800 Kgs.
