Abstract

Simulation can be an important step in the development of software for wireless sensor networks and has been the subject of intense research in the past decade. The simulation software should account for all possible factors affecting the wireless sensor networks. In this study we have addressed the question of correlated loss in among the communicating wireless sensor nodes. The results might help us update simulation software. Our approach is to check the fluctuations in the reception rates of the sensor nodes by introducing physical interferences between sender and receiver nodes. We performed two series of experiments in different surroundings. We show how the introduction of the line-of-sight physical interference between sender and receiver affects the reception rates. The results from this study can shed new light over the question of correlated loss among sensor nodes, experiencing the same kind of physical interference.
