Abstract Wireless Sensor Networks (WSNs) is an important technology that will be used in a variety of applications such as environmental monitoring, infrastructure management, public safety, medical, home and office security, transportation, and military. However, until now, WSNs and their applications have been developed without considering an integrated management solution. The task of building and deploying management systems, in environments where there will be tens of thousand of network elements with particular features and organization, is very complex. This task becomes worse due to the physical restrictions of the sensor nodes, in particular energy and bandwidth restrictions. The management application to be built also depends on the kind of application being monitored. This tutorial will present a perspective on emerging wireless sensor management, covering management issues and technologies, network management architectures, and opportunities. Traditional management and the differences of sensor networks management are described, and a new management dimension is introduced. Management architectures for sensor networks and information models are outlined, with emphasis on the MANNA architecture. WSNs have been designed without considering integrated management aspects. This may not be a problem for small networks but will definitely be when applications, in order to work properly, will need to reconfigure and adapt themselves based on profiles and information scattered over the network. Management of WSNs is a new research area that only recently started to receive attention from the research community.
