To implement a maintenance free and reliable sensor network is necessary in complex sensor systems nowadays. There are studies, which can control developers, who want to build an autonomous sensor network in a dynamically changing environment. The existing solutions have several drawbacks because of the diversity and complexity of the wireless type sensor networks. This paper introduces a sensor network architecture model, which is a good base to implement a simulation environment for the systems before implementing them. The introduced features make the possibility to fine-tune the operational parameters during the planning phase. In this way, the presented sensor network architecture is working based on the presented roles to provide its services.
