Energy Efficient Clustering Using a Wake-Up Receiver
Source: University of Pacific
The authors present a new energy-saving method for creating node clusters with similar sensor readings. The idea is to wake up a node/main transceiver only when data correlated to the node's own data is transmitted. This is achieved by encoding relevant parts of local data in a wake-up receiver's data pattern. Through this new protocol the building of clusters becomes highly energy-efficient, even if re-clustering is required, the energy consumed for clustering is still low. For environments where re-clustering is often necessary a clustering scheme can be used to further reduce the energy consumption.
