This paper presents simulation of WiMAX based system under jamming. The performance of the system was found out to greatly differ with the use of different jamming signals, allowing central areas to be identified, where system development should be focused on. In addition, from the basic theory point of view, rather surprising results were also found. This(More)
Mobile Ad-hoc Networks (MANETs) allow wireless nodes to form a network without requiring a fixed Infrastructure.Dynamic Source Routing (DSR) for mobile Ad Hoc network. It is a reactive source routing protocol for mobile IP network. Temporally-Ordered Routing Algorithm (TORA) routing protocol is for mobile ad hoc networks. It can be made to operate in both(More)
A novel improved VPN (Virtual Private Network) system based on SSL (Secure Socket Layer) protocol is discussed to overwhelm the defect of traditional SSL VPN. The concept, critical technique and working process of the geo-secured SSL based VPN are presented in details because they are very important to meet enhanced security requirement which is originally(More)
IPv6 is coming, whether we like it or not. It isn't a matter of new features or "killer applications," although those may come with time. Rather, it is the rapid depletion of the remaining IPv4 addresses that is leaving IPv6 as the only feasible alternative for the continued growth of networks beyond the next few years. Governments and service providers in(More)
In this paper we are given concept of our WiMAX (Worldwide Interoperability for Microwave Access) network performance for QoS monitoring and optimization solution for BS (Base Station) with multimedia application. In the communication sector, the optimal objective is to equate quality and cost. Due to its large coverage area, low cost of deployment and high(More)
In this paper, performance analysis of adhoc routing protocol is done on the basis of certain parameters. These parameters for the analysis are throughput, number of bytes received. The routing protocols compared are STAR and ZRP. The comparison also stands between the FTP and FTP generic systems. The performance evaluation will be done on the Qualnet(More)
Future generation networks will be characterized by variable and high data rates, quality of services, seamless mobility both within a network and between networks of different technologies and service providers. An important aspect of components in a global next generation network is standardization to allow vendor independence and interoperability. A(More)
