Khalaj<br>in the Proceedings of the 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2002. vol.5, pp. 2446- 2451, 15 Sept. 2002<br><br> <br/> The future wireless Internet is expected to consist of different types of wireless networks with different coverage range. The hybrid network of WLAN and WMAN can take advantage of them to offer high quality service. We propose a scheme to make handoff in IEEE 802.16 and IEEE 802.11 hybrid networks. The metric is the bandwidth of network level. The proposed algorithm is a bandwidth based adaptive fuzzy logic algorithm that can adapt itself with the dynamic conditions of the hybrid networks. It uses mobile host's speed and traffic in the WLAN as input fuzzy variables. This algorithm is designed to meet special requirements of hybrid networks. The scheme can reduce the unnecessary handoff probability because of the signal strength temporary dropping down or the high speed of mobile host. This handoff algorithm has much better performance than conventional algorithms and can be extended to other heterogeneous networks.
