A Simulation Framework For The Performance Evaluation Of Localisation Techniques Over Wsns

Wireless sensor networks (WSNs) are nowadays considered to be a very active research field. WSNs consist of interconnected small devices, which are managed by users. Their demands in hardware are limited and the usage of particular communication protocols lead in great autonomy.. WSN application is the localization of targets invading in the area covered by sensors' range. This target may be an animal, human, object or anything else. Localization can only take place when the sensors are capable of processing data and of communicating with each other. When these conditions hold, localization is achieved. A simulation environment has been developed in Matlab for studying the above described problem, where the localization algorithm may be integrated together with different scenario parameters. These scenarios have been implemented for evaluating the localization algorithm performance for different mobile object trajectories and speeds as well as for different network topologies. Finally, the evaluation results are discussed and conclusions drawn are presented.
