WLAN is a type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes. A mobile ad hoc network (MANET), sometimes called a mobile mesh network, is a self-configuring network of mobile devices connected by wireless links. In this paper, we propose strategy for internetworking of WLAN and MANET. MANE...

... in IEEE 802.11 are classified into two structures, such as infrastructure and ad hoc [8]. In infrastructured structure, access point (AP) is easily found in a network, as shown Fig ure 4. Basic unit for infrastructured structure is Basic Service Set (BSS), where station group communicates each other with no help from AP or others. ...

... Therefore, a ubiquitous communication service would be welcome in several industrial fields, such as transportation [4,5], manufacturing [6], and military [7,8]. Moreover, these healthcare-related examples can be found in some reviews [9] and forecasting [10] articles. The coverage rate of Wi-Fi is often limited [2,3], because the signal dead ends will result in wireless disconnection. ...
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.
To enhance the computer resource access of mobile nursing carts in the healthcare field, it is necessary to provide a continuous wireless mechanism. Because the web-based utilization might switch among diverse applications, a design for a one-to-many switching tunnel is necessary. This paper illustrates a revised version of our original one-to-one stream control transmission protocol tunnel (SCTP-Tunnel) software. This middleware is implemented by the ANSI C programming language on the Ubuntu operating system, and the related coding techniques are disclosed. A complete experimental measurement of this one-to-many SCTP-Tunnel for different data packets is also demonstrated. The turn-around times per data packet in the application layer for small (1 kB~1 MB) and large (5 MB~1 GB) numbers of data packets are approximate 29.005 ms and 6.424 ms, respectively. Such system software can be simply integrated with electronic healthcare services and ubiquitously utilized in the healthcare field.
