Security for wireless devices is turning into vital day by day. When internet connection is available for mobile devices all the communication pass through some intermediates. The end to end security is the major issues in wireless security contrivances like mobile phone and PDA(Personal Digital Assistant).When mobile contrivance wants to communicate to the web server through internet the all the communication pass through the Wireless Application Protocol gateway. This Wireless Application gateway protocols interprets all the convention utilized in Wireless Application gateway to the protocols utilized in the cyber world. The Wireless Application Protocol proxy server use encoding and decoding technique for the content to reduce the size of the data that has been sent through the wireless link. The communication between the mobile phones and wireless application protocol is secured by utilizing the safety protocol is termed Wireless Transport layer security. The communication between the WAP entrance and net server is secured through the TLS/SSL security protocols. This paper presents an evaluation study of wireless and wired network utilizing OPNET simulation implement. This paper simulated 2 different scenarios comparing wireless mobile client communication utilizing Wireless Transport Layer Security gateway with MD5_RSA encryption and Firewall gateway TLS encryption utilizing MD5_RSA.The analysis results shows that how to provide the point to point security between wireless client to web server by proper utilizing the hybrid security protocol.
