Abstract:
In this paper we report the design and implementation of the networking and communication part of a WSN application for measuring industrial and residential acoustic noise. The network is formed in tree topology and a global synchronization is achieved. A link-state routing is tightly binded with the synchronization so that the network overhead is greatly reduced. Transmission scheduling is implemented in the network due to the fact that noise measuring is time-correlated, resource-consuming, and uninterruptible. The application is built on the CiNet cross-layer protocol stack. In our testbed, two IEEE 802.15.4 platforms (Chipcon CC2420 and Jennic JN5148) worked seamlessly. The uniqueness of this application is that it combines routing, global synchronization, and scheduling under a single framework. The network has been already deployed in the residential area of Kokkola city on the western coast of Finland.
