Most wireless networks are specified as using the data link protocol, i.e. layer 2 (L2). Recently, IoT and big data processing have promoted the use of wireless sensor networks to connect and send data to data center applications over 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 were developed to allow applications 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 that this VPN be used as a test bed for small IoT businesses and institutions before they start to implement an IP stack on their systems.
