Service Management in Wireless Sensors Network

Wireless Sensor Networks (WSNs) are becoming an increasingly technology that will be used in a variety of applications. However, until now, WSNs and their applications have been developed without considering a management solution. In this paper, we have evaluated a management architecture for WSNs, called MANNA, where the service and configuration management are analyzed. We focus on a class of hierarchical and heterogeneous WSNs where sensor nodes collect data and send them to an observer continuously along time. The cost of sending data continuously may lead to a more rapid consumption of the scarce network resources and, thus, shorten its lifetime. However, this is an important kind of WSN and we show that the use of some management services proposed by MANNA did not affect the network behavior and can improve the performance metrics depending on the configuration. At the observer, the management application monitors the Quality of Service. Accuracy, latency, coverage area, and energy consumption are proposed as important parameters in our case study.
