The Zigbee Wireless Technology fits into a market that is not completely filled by other technologies.For example, other wireless technologies like WiFi and Bluetooth are striving to go faster, add more features, provide streaming of high definition content and run for hours. The WAP stack consists of the following layers: WAE – WIRELESS APPLICATION ENVIRONMENT. The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family.Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.. Application-specific protocol architectures for wireless networks The Repository makes it possible to store WTA services in device which can be accessed without accessing the network. My thesis is that this harsh environment with severe resource constraints requires an application-specific protocol architecture, rather than the traditional layered approach, to obtain the best possible performance.
