The main theme of this paper is to derive the performance of the Hub, Switch,Bluetooth,Wi-Fi and Wimax technology using the Queueing Petri-net model and the Markov model with applying of RSA and Algorithm. This paper mainly focuses on comparison of M/M/1 AND M/M(a,b)/1 using mat lab to find performance on wired and wireless technologies in terms of service rate, arrival rate, Expected waiting time and Busy period. When comparing the service rates from the Hub network, switch network, the Bluetooth, Wi-Fi and Wimax technology. Wimax technology it has been found that the arrival rate, service rate, Expected waiting time and Busy period is very efficient in M/M (a, b)/1 for implementation. The values obtained from the Wimax technology can use for calculating the performance of other wireless technologies. QPNs facilitate the integration of both hardware and software aspects of the system behavior in the improved model. The purpose of Cryptography is to send the secured information from one system to another through the Wimax technology with security measures. Steganography is the art of hiding information in images, sounds or any other file format than the routine format. Queueing Petri Nets are very powerful as a performance analysis and prediction tool. By demonstrating the power of QPNs as a modeling paradigm in further fore coming technologies we hope to motivate further research in this area.

In wireless networks, to provide quality of service by means of resource allocation the protocols need to be evaluate a lingering bandwidth estimation for further allocationHowever, there is no standardized mechanism or method has been proposed to accurately evaluate the amount of available resources on a given channel. Such an evaluation would, lead to optimize bandwidth utilization for applications of mobile adhoc networks like multimedia dataflow. We proposes a new techniques to estimate a bandwidth of a node in IEEE 802. 11 based mobile adhoc networks. We show by simulations that our technique provides we show by simulations that our technique provides an accurate estimation of the lingering bandwidth on wireless links in many ad hoc configurations and an efficient delivery ratio & reduce delay time in the environment.
