Demo Abstract: Spectrum Agile Medium Access Control Protocol for Wireless Sensor Networks

In this demonstration paper we describe a low-power spectrum agile medium access control protocol for wireless sensor networks. Our protocol allows sensor nodes to dynamically select an interference minimal channel for data communication. It does not pose any synchronization restrictions on the nodes and effectively handles the dynamics of the network such as new nodes joining and old nodes leaving the network. During the “table-top” demonstration, we show the various energy efficient spectral sensing features of the protocol on which the dynamic channel selection is based. As part of the demo we describe the protocol details and show that even in highly crowded spectrum and environments with random interference, sensor nodes are able to communicate in a reliable and energy efficient manner.
