A visitor, Zhou Jianguo, from Wuhan University in China is implementing and evaluating decentralised algorithms with our wireless sensor network, RISERnet. Decentralized algorthms allow in-network processing of data and are the next step in embedding further intelligence in RISERnet. In stage one, the decentralised algorithms will be validated with indoor experiments where the ground truth is known accurately. Depending on the experimental results, we will consider and design future outdoor and field validation experiments.
