Wireless sensor networks (WSNs) can significantly enhance the capability to monitor and control working environments. However, to fulfill the issued sensing tasks the network topology with desired properties (e.g. coverage, connectivity, lifetime, etc.) has to be created. The adequate deployment of sensor devices in the sensing area is needed for acquiring and managing data. In many applications it is necessary to use mobile devices that can move the sensors to the desirable positions in a given workspace. In this paper, we investigate the problem of mobile sensors deployment to get high coverage of a sensing area and ensure network connectivity. We discuss and compare two approaches to the positioning of sensors - pre-defined and self-configuring deployments. Finally, we propose a two-phase approach to WSN formation process, in which created preliminarily regular network topology is adapted to a given application scenerio. We assess the quality of deployment strategies based on the results of simulations.
