A Practical U-Healthcare Network with Security and QoS


Huang, Shiow-Yuan, Hung, Cheng-Chan, Lee, Cheng-Chi, Journal of Digital Information Management


1. Introduction

As a consequence of the developments of science and technology, medical sensing technology is evolving from the previous electronic care (e-care) to the ubiquitous care (U-care). Government promotion of a U-Taiwan plan indicates the coming of the ubiquitous society. What is meant the Ubiquity? It means mobility of sensor networks, security, standard, integration (health system, service model), and CAD (Computer Assisted Decision). This paper studies the above-mentioned characteristics of the Ubiquitous technology.

As shown in Figure 1, security covers the scope of the whole system, and QoS covers 80%. Therefore, security and QoS will be the very important in the U-healthcare system. However, most of the ubiquitous health systems [1], [2], [3], [4], [5] have not yet proposed a system with both network security and QoS. In this paper, we will use the existing security mechanisms and methods of QoS to achieve the needs of U-healthcare network.

In addition, we use the advantages of ubiquity of IPv6, such as large address space, an extension of encrypted authentication, quality of service, enhanced ability to address, mechanisms to simplify the header format to this system. The Internet of the future will support the basic features with multimedia, security and mobility. IPv6 is fully equipped with the above-mentioned features and the ability of ubiquity. Therefore, IPv6 will be the best choice for the next generation Internet protocol, which is being applied to U-life and to the way of ALL-IP.

This paper studies a U-healthcare network platform with security and QoS. The use of the new IPv6 security features and QoS options improves the environment of the U-healthcare network by not only sharing the cost of healthcare and human resources, but also by being a long-term monitor of unusual health symptoms. The U-healthcare environment will be the primary defense for medical care, safety and the health of human beings. A U-healthcare environment with security and quality of service is needed for our development.

The remainder of the paper is organized as follows. We describe the U-healthcare network demand and problems encountered in Section 2. In Section 3, we review the properties of IPv6 and describe our implementation of the system, with security and QoS. In Section 4, we present the test system design with IPv6. Finally, Section 5 concludes the paper.

2. U-healthcare Network Demand

Along with social and economic development, medical advances have enabled people to increase their life expectancy, with the consequent gradual aging of the population. The problem of an aging population will need urgent attention in the 21st century. The increasing demand for elderly health care is the most pressing current need and will continue to in the future. Therefore, to consider the increasing demand for elderly healthcare as well as mobile care, it is necessary to establish a new type of healthcare system, one with a network technology to provide U-care services. When a person has urgent need of heath care, the U-healthcare system issues an immediate warning through the network, so that the healthcare workers will be able to locate the person quickly and efficiently and give the necessary emergency treatments.

Compared to the current IPv4 networks, IPv6 is the next generation Internet protocol and has many new features, such as large address space, Internet operations support, an extension of the encrypted authentication mechanism, enhanced addressing capabilities, automatic addressing mechanism, simplification of the header format, and so on. Based on the above advantages, this paper chooses IPv6 as a U-healthcare network protocol. As the U-healthcare network has a large number of sensor nodes, the transmission network will be the limiting factor for transmission quality. It must also be borne in mind that wireless networks have problems of network security. …
