EXTENSIBLE FRAMEWORK FOR MITIGATING INTERFERENCE PROBLEMS IN WIRELESS NETWORKING

摘要

Described is an architecture comprising a flexible and extensible framework embodied in a robust coexistence service that couples sensed RF spectrum (interference) data to modules that process the data into dynamic feedback information used to mitigate network communication problems caused by the interference. Via a driver, spectrum sensor hardware is connected to the framework running on a computing device, where the condition and quality of various wireless networking channels are assessed by external modules plugged into the framework. Modules comprise include a classifier component that examines the sensed-data and classifies it, and an application program that processes the classified data, possibly for mitigation. Mitigation-related information is fed to a feedback mechanism to adjust network parameters to avoid the sensed interference. The robust coexistence service also distributes control data corresponding to the mitigation information to other remote computing devices in the wireless network for use in mitigating their interference problems.
