Abstract. 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.Keywords: role based, wireless sensor networks, sensors, sensor architecture model, maintenance free sensor networks, dynamic sensor network environment. IntroductionNowadays, one of the main problems in sensor networks is to solve the problems that arise from network and resources maintenance. We need to optimize the efficiency and reliability of the systems. The main goal of a sensor networkis to gather measurement data from the environment. From a processing system point of view, it is a loss to maintain this kind of network. If the sensor network can handle these functions alone, then the processing network operation can be more reliable. There are two different control types. One, is a centralized control method, where the processor entities provide network guidance. These networks are more common than a non-centralized system, because the maintenance is taken on one side only, so problems and network errors are easier to recognize and repair. Therefore, most solutions use centralized control method based configuration. In the current literature there are several system models and maintenance algorithms presented, which can handle large sensor networks. The main goal of these models is to verify system channels and other items in a fast and reliable fashion. The center of the * This work was supported by TÁMOP-4.2.1/B-09/1/KMR-2010-0002.

Supporting dynamic reconfiguration is required even in highly constrained embedded systems, to allow patches and updates to the embedded systems software, and to allow adaptations to changes in environmental and operating conditions without service interruption. Dynamic reconfiguration, however, is a complex and error prone process. In this paper we report our experience in implementing safe dynamic reconfigurations in embedded devices with limited resources. Our approach relies on a component-based framework for building minimal and reconfigurable operating systems and the use of a domain specific language (DSL) for reconfiguration.

A wireless sensor network is a network made up of many tiny intercommunicating computers equipped with one or several sensors. Each tiny computer represents a node of the network. The nodes are self‐contained units typically consisting of a power supply with limited capacity, a radio transceiver, a microcontroller, and one or more sensors. This article gives an introduction to wireless sensor networks for structural health monitoring, shows the general architecture of sensor nodes, and overviews current hardware and software platforms. Furthermore, it shows the characteristics and limits of such monitoring systems and gives advice to choose a suitable platform to an application. Because nodes are powered by an autonomous source, energy‐related aspects, energy storage, and scavenging are presented as well.
