Table 5: \(Cont.\)that data, they did not need the raw data. Those mobile clients ask for the information starting with the cloud and the cloud performs information recommendations and predicts information after giving back these required data to the clients [61; 62]. After predicting data, the cloud needs information characteristics that are more inclined to mobile users regarding that information. Cloud informs WSN to use this data to streamline the sending data by WSN.
