Efficient and Secured Application with Passive Measurement in WIFI Network

M. Kiruba , Mrs. K. Akilakumari M.E.,

Co-operative communication is one of the fastest growing areas of research, and it is likely to be a key enabling technology for efficient spectrum use in future. The key idea in user-cooperation is that of resource-sharing among multiple nodes in a network. The reason behind the exploration of user-cooperation is that willingness to share power and computation with neighboring nodes can lead to savings of overall network resources. Wi-Fi networks provide an enormous application space for user-cooperation strategies to be implemented. In traditional communication networks, the physical layer is only responsible for communicating information from one node to another. In contrast, usercooperation implies a paradigm shift, where the channel is not just one link but the network itself. It demonstrates an application based on selfish carrier sense behavior. The experimental and simulations result demonstrates that the proposed approach to estimate interference relationship is more accurate and quite competitive. It can be implemented in real wireless LAN environment as well as NS-2 simulation. The metric of selfishness is used to estimate selfish behavior matches closely with actual degree of selfishness observed.
