The Implement And Performance Research Of WAP Protocol In OPNET

WAP means Wireless Application Protocol, it integrates the mobile communication and Internet. WAP is designed to adapt to the bounds of wireless networks (such as low bandwidth, high latency, less connection stability and so on) and the bounds of wireless device (like limited input facilities, limited battery power, limited display, memory and CPU). Another characteristic of WAP is that it scales across a broad range of wireless networks and bearers. The bearers can be SMS, circuit-switched data, packet-switched data, and the networks can be GSM, IS-95, GPRS and even 3G.This paper introduces the WAP stack first and then simply introduces the simulation tool OPNET; the following part analyzes the WAP stack in theory, then research the function of WSP and WTP. After that it expatiates on the detailed procedure of modeling the WAP in OPNET and analyzes the characteristics of performance of WAP through the result of simulations. Finally this paper shows the shortage of WAP and predicts the future of WAP.Because there isn't the WAP module in OPNET, I implement the WAP protocol in OPNET. It will facilitate the performance research of WAP for the future.
