Abstract
In order for heterogeneous unlicensed devices to co-exist on the same frequency band, the frequency interference avoidance mechanism is necessary. In this paper, a frequency interference between WLAN and WPAN systems that operate at 2.4 GHz ISM band was analyzed in the MAC layer. We observed that WPAN systems suffer from severe interference from WLAN systems. To avoid this interference problem, we propose a new channel shift algorithm for WPAN systems. We showed that the proposed channel shift algorithm is better than the traditional WPAN system which uses a fixed channel in terms of throughput.
