Design of Distributed SHM Algorithms Within WSNs—A Cluster-Based Approach

One of the most energy consuming operations in a WSN is wireless data transmission. To overcome this, computation power on the wireless sensor node can be utilized. Instead of streaming the sampled data directly to a central unit, the collected data are processed and only the processed information, which uses fewer bits than the original one, is transmitted. From this perspective, embedding SHM algorithms within a WSN can be an effective way to decrease the energy consumption.
