Distributed Federated Sensor Network

Wireless sensor networks have been used increasingly widely in the modern world. The sensor nodes in the network system not only have a small physical size, but also have low energy consumption albeit with low processing ability. Wireless sensor networks are used to collect data in remote or harsh conditions, which in reality requires a number of different heterogeneous sensor network. There are a number of challenges here such as determining the equipment and services to use, the data query methods, the methods for network connection, as well as numerous security issues. In fact, how to collect data from multiple sensor networks subject to the user´s requirement is becoming a most critical problem. In this paper, we present a demonstration for a data centralized Federated Sensor Network. Our demonstration shows that the centralized architecture is not a perfect solution for on-demand sensor data. Therefore, we introduce a novel distributed Federated Sensor Network architecture. A comparison between centralized and distributed architectures for Federated Sensor Networks is given at the end of the paper to inform any possible implementation.
