it is not transfer protocol & WAP does use HTTP developed for delivering data across the cellular telephone system and optimized for delivery channels that have low bandwidth.

WAP (Wireless Access Protocol) isn't a transfer protocol like HTTP and it uses complete protocol stack.

WAP is not actually a protocol at all, in the sense that HTTP and IP are protocols. In fact, WAP involves multiple protocols and a complete network architecture for delivery of wireless content.
These three protocols can be thought of as "glue layers" in WAP:

* Wireless Transaction Protocol (WTP)
* Wireless Transaction Layer Security (WTLS)
* Wireless Datagram Protocol (WDP)

WTP provides transaction-level services for both reliable and unreliable transports. It prevents duplicate copies of packets from being received by a destination, and it supports retransmission, if necessary, in cases where packets are dropped. In this respect, WTP is analogous to TCP. However, WTP also differs from TCP. WTP is essentially a pared-down TCP that squeezes some extra performance from the network.
