Wireless Transmission Security Protocol Wtls Simulation Study

Technique of simulation, especially that of computer-simulation is a comprehensive and experimental science. It is established in the theories of the analogy and control. It can simulate the system behaviour only by calculation and it needn`t abstract and simplify the system . It can observe the detail of the whole system accurately. It carries out the simulation of the network, so it is a kind of very valid method.The main factor that affects the network capability includes the bandwidth, the node function, the topology of networks, the router arithmetic, the protocol of communication, and the network application etc.For the sake of the improvement of networks` capability characteristic, many researchers put forward many outstanding tentative plans and methods. But to more complicated Internet and the mobile network system, it is hard to analyze. So for further studying the technique of WPKI, we really must carry on simulate to the function of WPKI (such as customer quantity, responding time and bandwidth to request etc.). Thus under the condition of not on the scene, we can get the WPKI function parameter to carry on the capability valuation, and put forward some directive suggestions, making the WPKI attain the best capability under the condition of certain.This paper will put forward the model of WTLS protocol by OPNET, building up a terrace of WTLS to simulate it. Under the support of that terrace we will carry out simulation of single node and multiple nodes (5 nodes).
