WAP access to SCADA-typed database system

This paper discusses the use of the Wireless Application Protocol (WAP) architecture to provide a wireless channel to access the SCADA database operating in the power process plant via Internet network protocol. The WAP architecture enables mini-browser operating in a wireless mobile phone such that information sessions between two ends can be established and displayed in a small display window. With the WAP protocol stack, advanced features such as data encryption, authentication, synchronization, are supported throughput the wireless sessions. Hence, under the wireless environments, the supported WAP service would provide a secure and reliable access to a sophisticated database. This interactive mode provides an instant channel to retrieve important data from transactions as well as conducting computational processing on some time-critical events
