A mobile healthcare solution applied to elderly people is presented in this paper. Each person can have health records stored on a smartphone or tablet and managed by a web server. When the need arises, medical professionals can access this personal repository of health information as a web service. The work presented by the authors started by creating a cloud middleware system, SOPHRA, that supports interaction between mobile providers and requesters, in this case all medical professionals. The purpose of the middleware is to manage device mobility, and data synchronization and coherency. For those purposes, all users need to be registered with the middleware system and cloud resources allocated as required at runtime.

The addition of this paper is the security of the patient data using authorization and encryption. An error tracking system is designed to provide fault tolerance. Several experiments involving tablets and a private cloud were carried out. Obviously the results would be different (higher response time) if a cloud system such as Amazon Elastic Compute Cloud (EC2) were used, changing times to seconds and not milliseconds.

An interesting development of this project would be to allow direct interaction between mobile providers and requesters in a peer-to-peer (P2P) mobile ad hoc network.
