This paper presents a live-video service using multicast in wireless network. The switching/multicast agent (SMA) in this system provides multicast for effective use of network resources in WLAN and reduces the load of video server and access points(AP). Also, the SMA and AP support a handover mechanism for moving mobile nodes(MN) using identification number(ID#) of AP (AP_#) that the MNs are visiting while they move within WLAN. The AP_# is added to IP address assigned from the first accessed AP. Except the MN receives multicast group address(MGA) from SMA, this IP address never changes even if the MN moves among other APs. The overhead for handover using AP_# is negligible in video service. The proposed live-video system using multicast provides a seamless video service by adding AP_# only without reassigning of IP address from a new AP when MN moves one AP to another.
