A Novel Cognitive Frequency Hopping Mechanism for Bluetooth Network

Abstract:

Bluetooth is a short-range wireless technology that operates in the 2.4GHz unlicensed ISM band, so it will inevitably encounter the interference from other wireless systems and other Bluetooth piconets. Because of the flexible, efficient and reliable spectrum access by adapting the radio’s operating characteristics to the real-time conditions of the environment, cognitive radio technology is apply in Bluetooth network. In this paper, a novel cognitive frequency hopping (CFH) scheme based on channel quality detection is proposed. The coexistence mechanism of Bluetooth network and link quality detection method is described and discussed. Simulation results shown the performance of the proposed CFH system is improved.
