Localization and Routing against Jammers in Wireless Networks

Jammers are the devices that disturb the communication in wireless networks. If the actual position of jammer is located then it is possible to eliminate the disturbances in communication networks. This project designs a framework to locate the position of a single or multiple jammers more accurately. Many present jammer localizing schemes use indirect methods considering the hearing ranges, packet delivery ratio etc. This project uses direct methods that are the jamming signal strength. Estimating jamming signal strength is very challenging because the signals may be embedded in other signals. And the existing methods of locating do not provide global optimal solutions so this project performs some search algorithms for achieving the global optimal solution.
