Abstract

The hybrid network of WLAN and WMAN can take advantage of them to offer high quality service. In this paper, we first propose a scheme to make vertical handoff between IEEE 802.16 network and IEEE 802.11 network. The metrics is the available bandwidth. The algorithm can reduce the unnecessary handoff probability because of the signal strength temporarily dropping down. Next, a two-hop-relay architecture with mobile nodes to be relay gateways is presented. The system can utilize temporal channel quality variation to achieve higher capacity and extend the coverage range of IEEE 802.11 networks. This method can be extended to other heterogeneous networks.
