Functional and Information Models for the MANNA Architecture

Wireless Sensor Networks (WSNs) are becoming an increasingly 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. WSNs will also play a key role in pervasive computing where computing devices and people are connected to the Internet. Until now, WSNs and their applications have been developed without considering a management solution. This is a critical problem since networks comprised of tens of thousands nodes are expected to be used in some of the applications above. This paper presents an information model for wireless sensor network proposed by MANNA management architecture that take into account specific characteristics of this type of network. Some of them are restrict physical resources such as energy and computing power, frequent reconfiguration and adaptation, and faults caused by nodes unavailable. The MANNA architecture considers three management dimensions: management functional areas, management level, and WSN functionalities. These dimensions are proposed to the management of a WSN and are the basis for the information model.
