Introduction to the special section on Big data and IoT in e-healthcare

Several contributions that would help readers to enhance their knowledge and motivate them to work on Big data and Internet of Things (IoT) in e-healthcare are introduced. Big data storage and processing are considered as one of the main applications for cloud computing systems. On the other hand, Vijayakumar et al propose SmartSMS protocol is to minimize the computational complexity of the Mobile Station and the Authentication Server. In addition, the proposed work also minimizes the communication complexity involved in secure SMS communications. The simulation results show that the proposed protocol shows lower computational and communication overheads compared to other protocols in the literature and show promising results.
