The WAP architecture is layered, allowing for adaptability and expansion. The main layers are WDP, WTP, and WSP, with additional layers like WTLS and WAE. The network operator’s method is the foundation, with WDP ensuring synchronization, WTLS providing encryption, WTP managing data transfer, and WSP determining exchange type. WAE is the highest level, allowing for customization.
In general, the structure of wireless application protocol (WAP) architecture is layered, with each component stacked on top of each other. This architecture is sometimes referred to as the “WAP Stack”. The layered structure allows the WAP to accommodate other components as needed, making it adaptable and expandable. The three main layers of WAP architecture consist of the Wireless Datagram Protocol (WDP), the Wireless Transaction Protocol (WTP), and the Wireless Session Protocol (WSP). Other layers such as Wireless Transport Layer Security (WTLS) and Wireless Application Environment (WAE) are also often included in the stack and have important functions.
Underlying the WAP architecture is the network operator’s method, or medium in which information is sent, such as short messaging service (SMS) for text messaging or general packet radio service (GPRS). for mobile internet connection. Just above the vector is the WDP, which becomes the medium between the vector and the layers above it. It ensures that the WAP is synchronized correctly with the operator method so that the connection is stable, consistent and continuous.
Just above the WDP is the WTLS. As the name suggests, this layer in the WAP architecture ensures that data is protected and restricted from a third party “interceptor”. This means that WTLS usually embeds encryption on messages passed from one network to another and checks the message and the sender’s network for authentication. WTLS also ensures that the message maintains its integrity and is not altered when it is received.
The WTP, in addition to the WTLS, manages the data transfer. You can think of the WTP as a traffic enforcer that allows messages to be sent and received. For example, WTP does not allow one mobile phone to send messages when there is no signal, nor does it allow another mobile phone to receive messages when it is turned off. This level is also responsible for organizing messages, which is why data is usually sent based on the time and date of the transaction.
After the WTP comes the WSP, which determines whether double exchange of information is required during data transfer or if only one-way exchange is required. When two-way exchange is involved, such as in chat rooms and video conferencing, the WSP redirects data to the WSP to handle the data flow. If a one-way transaction is performed, such as in video streaming, the WSP allocates data to the WDP to ensure that data packets are sent continuously until the data is complete.
The highest level of the WAP architecture is the WAE, which provides programmers and other users with a place to create and modify the content and way an application works. This layer can contain HTML (HyperText Markup Language) codes for web pages and the URL that serves as an address to a website. Among the layers of the WAP architecture, WAE is probably the most accessible to any user who wants to customize the own website, replace the background of pages, change the color of texts and even program your own game and tools.
