Application and Research on Performance Analysis and Security Implementation in Hybrid Networks

Abstract

Background/Objectives: Security in wireless and wired networks is a serious issue in IT industry because of its performance, capacity and cost. It concern with the secure transmission of traffic between the networks elements. As compare to wired network, wireless net- work security somewhat more concentrating. It covers a gigantic of computer networks, both public and private, that are used in everyday jobs; conducting transactions and communications among businesses, government agencies and individuals. In order to solve to problem of WAP gap for wireless devices like mobile phone and personal digital assistant, in this paper, introduces the performance analysis of wireless and wired network to provide the end to end security. Methods: The main idea is to propose the enhanced protocol to overcome the security gap using opnet modeler as simulation tool. In this model two scenarios are discussed. First scenario is based on communication from wireless device to gateway and second scenario is based on gateway traffic to wired server. Different simulation results based on various parameters like delay, throughput, and re-transmission attempts for wireless networks. Findings and Improvements: A simulation environment was developed to measure various parameters including the traffic received, traffic send, response time is considered for server side applications in wired networks. Furthermore, security parameters are implemented on the firewall to improve the end to end security for hybrid networks. As a result the proposed protocol is observed to be better for wireless network for the parameter considered.
