A hospital's mobile nursing cart can collect clinical data via Wi-Fi networks and save data in the server side. This service not only provides better medical care, but also enhances staff productivity. However, the coverage of Wi-Fi is limited and signal dead ends will result in wireless disconnection. This problem can be solved by switching between Wi-Fi and 3G. The physical connection must be disconnected and be reconnected again. Therefore, it is interesting to design a mechanism to keep the physical connection continuous. This research designs a Stream Control Transmission Protocol Tunnel (SCTP-Tunnel) middleware. This middleware can be used to build a tunnel between client and server sides such that the SCTP packets can carry the TCP packets and solve the problem of disconnection caused by the one-to-one TCP. The proposed SCTP-Tunnel is compatible with IPv4 and IPv6 and can be adopted without modifying the applications. This design utilizes the SCPT packet acknowledge and multi-homing mechanisms to achieve network fault tolerance. It is feasible to provide a tunnel service via the SCTP-Tunnel and connect to service indirectly without changing the original system architecture to approach the Wi-Fi and 3G switching seamlessly. Such a service will also provide quality long-term healthcare services in the healthcare enterprise.

Mobile handheld devices are rapidly using to implement healthcare services around the World. Fundamentally, these services utilize telemedicine technologies. A disconnection of a mobile telemedicine system usually results in an interruption, which is embarrassing, and reconnection is necessary during the communication session. In this study, the Stream Control Transmission Protocol (SCTP) is adopted to build a stable session tunnel to guarantee seamless switching among heterogeneous wireless communication standards, such as Wi-Fi and 3G. This arrangement means that the telemedicine devices will not be limited by a fixed wireless connection and can switch to a better wireless channel if necessary. The tunnel can transmit plain text, binary data, and video streams. According to the evaluation of the proposed software-based SCTP-Tunnel middleware shown, the performance is lower than anticipated and is slightly slower than a fixed connection. However, the transmission throughput is still acceptable for healthcare professionals in a healthcare enterprise or home care site. It is necessary to build more heterogeneous wireless protocols into the proposed tunnel-switching scheme to support all possible communication protocols. In addition, SCTP is another good choice for promoting communication in telemedicine and healthcare fields.
