Abstract
PurposeWe propose a collaborative and secure transmission scheme in order to safely and efficiently transmit medical data and provide telemedicine services, lighten the load on wireless access networks, and improve the quality of medical treatment such as surgery.MethodsFirst, the transmission technology based on opportunistic networks is used to upload patient physiological data and share medical information. Second, we propose a trusted transfer scheme based on the circle of friends, which is constructed with historical encounters and social features of nodes. This scheme takes the forwarding policy of each packet by close friends to effectively prevent the participation of strangers, and avoid privacy issues and deal with selfish behaviors. At the same time, the structure of friend circle is beneficial to the improvement of medical data transmission. Third, we present a lossless compression scheme with less computation and higher compression ratio to reduce the amount of medical data and improve the performance of the transmission.ResultsThe experimental results show that the proposed scheme is effective and has good transmission performance while ensuring the safety and reliability of media data.ConclusionThe mobile healthcare faces some challenges such as the vastness of medical data and sensitivity of patient information. Using opportunistic networks to transmit medical data in mobile healthcare is a good solution, which can effectively divert and offload the data traffic of mobile Internet. The structure of friend circles and the technology of data compression are beneficial to safely and efficiently transmit the patient’s physiological parameters and medical health information.
Highlights
With the development of society and the improvement of living standard, people have a higher demand for medical services and health management
The multipath transmission algorithm based on friend circles is shown in algorithm 1, its process is explained as follows: At a certain point, the node vc has a data packet p to send to the node vd, and it meets the node vi

Summary
With the development of society and the improvement of living standard, people have a higher demand for medical services and health management. Mobile healthcare (mHealth), known as mobile health, can provide medical services and information via the use of mobile communication technologies, such as tablets and smartphones. It gives an effective solution way for people to listen to the advice of doctors or access to a variety of health-related information (including physical examination, health care, disease assessment, medical treatment, and rehabilitation) whether at home or on the road. From the aspect of user size, they reached 72 million in 2014 and 138 million in 2015.
