Abstract

In this paper, a new adaptive frequency hopping (AFH) technique is proposed in an attempt to mitigate the interference between Bluetooth (IEEE 802.15) and wireless local area networks (WLANs) (IEEE 802.11b). The new AFH technique optimizes the carrier spacing according to the network load and noise level. For a given overall bandwidth and data rate, reducing the separation between adjacent channels has a positive effect of increasing the number of available hopping channels. This can definitely lead to decreasing the collision rate. On the other hand, decreasing the channel spacing increases the adjacent channel interference. Therefore, there exists an optimal channel spacing that maximizes the network throughput. Rayleigh fading was considered and results show that the new AFH technique outperforms existing AFH techniques for a wide range of network loads.
