Abstract :
We have proposed hotspot network based on layer 2 forwarding using movement notification packet for seamless handover. Descriptions of address table for the layer 2 forwarding were renewed at the time of receiving the movement notification packet, which is sent from mobile terminal at changing connection. In order to receive several packets buffered in previous access point, we propose the mobile terminal with two receivers; main and sub receivers. The mobile terminal receives buffered packets in the previous access point using sub receiver. We evaluated throughput of the mobile terminal with dependence of handover frequency. IEEE802.11b modems were used as wireless interfaces. From the experimental results, degradation of throughput with handover was negligibly small compared with throughput without handover
