Link strength predictions based on spatiotemporal correlation of features in proximal links

A method for predicting wireless link strength, comprising:

• maintaining a first history of link strengths between a first wireless node and a second wireless node and a second history of link strengths between a third wireless node and a fourth wireless node;
• performing a spatiotemporal correlation between the first history and the second history, if a change in the link strength between the first wireless node and the second wireless node is observed;
• and,
• predicting future changes of the link strength between the first wireless node and the second wireless node from observations of the link strength between the third wireless node and the fourth wireless node using a result of the spatiotemporal correlation, if the result of the spatiotemporal correlation is positive and significant.
