We 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.
First, 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.
The experimental results show that the proposed scheme is effective and has good transmission performance while ensuring the safety and reliability of media data.
The 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.
为了安全有效地传输医疗数据并提供远程医疗服务，减轻无线接入网络的负担，提高手术等医疗质量，我们提出了一种协作和安全的传输方案。
首先，利用机会网络的传输技术上传患者生理数据并共享医疗信息。其次，我们提出了一种基于朋友圈的可信传输方案，该方案利用节点的历史相遇和社交特征构建。该方案采用密友转发策略，有效防止陌生人的参与，避免隐私问题和处理自私行为。同时，朋友圈的结构有利于提高医疗数据的传输性能。第三，我们提出了一种具有较少计算量和较高压缩比的无损压缩方案，以减少医疗数据量并提高传输性能。
实验结果表明，所提出的方案在保证媒体数据安全性和可靠性的同时是有效的，并且具有良好的传输性能。
移动医疗面临着医疗数据庞大和患者信息敏感等挑战。在移动医疗中利用机会网络传输医疗数据是一个很好的解决方案，可以有效地转移和减轻移动互联网的数据流量。朋友圈的结构和数据压缩技术有利于安全有效地传输患者的生理参数和医疗健康信息。
