A bridging VPN for connecting wireless sensor networks to data centers

摘要

Most wireless networks are specified as layer 2 (L2), or data link protocol. Recently, IoT and big data processing have promoted the use of wireless sensor networks to connect and send data to data center applications using the Internet. To do so, the implementation of an IP stack on the wireless node, or the gateway of the IP and wireless L2 network, has been proposed. Both approaches are developed to allow the application on the IP network to access L2 wireless network nodes. However, since wireless sensor networks do not require any network protocol, an IP is not essential for collecting data. Therefore, we propose a novel bridging VPN for connecting wireless networks, in which the application and wireless end nodes are not required to acknowledge an IP address or network protocol. In this way, the IP network merely serves to transport the data link frames of wireless networks. We believe that this is another style of IoT, and recommend a small IoT businesses and institutions for use of this VPN as a test bed before they start to implement an IP stack on their systems.
