“…From the neighbor graph server, Station gets better scanned AP's data if there is necessity of handoff and handoff delay can be lessened. The overall execution of NG is as follow: The main advantages of this scheme are to sort out and manage the wireless systems and perform load balancing [8].…”

WLANs play a vital role in 4 th Generation (4G) cellular system due to its adaptability and mobility. The most important issue in wireless communication networks to provide seamless handoff. Handoff delay make of serious problem as a lot of research has been done in last few years to reduce the handoff delay incurred in the different level of wireless communication. The whole delay time of a handoff process is isolated into authentication , probe and re association delay time. So this paper reviews the brief description about the distinct handoff techniques used in wireless networks and analyze their merits and demerits. Some future research ideas are also suggested here.

“…Multicast technique can improve the efficiency of the deficient wireless link when sending the same multimedia data such as live-video, news and sports broadcasting [3,6]. A number of researches have progressed to solve the problems such as the overlay tree being cut off easily because of MNs' movement and excessive consumption of deficient wireless link bandwidth is due to the multiple copies of the same multimedia data [7,8,9,10]. But such researches are dealt with only one problem.…”

Mobile ad-hoc network(MANET) is a self-organized network over infraless structured radio links. And hybrid mobile ad-hoc network(HYMANET) is a network which is combined with infra(AP) and MANET. In these networks, one of the most critical problems is the deficient network resource for receiving multimedia streams. The other problem is that overlay connection tree shuts down frequently following mobile node(MN)s' movement. For solving these problems, this paper generates multi-paths overlay multicast connection tree using multiple parent-child relationships according to the number of hops towards AP(access point) in hybrid ad-hoc network. The proposed method can be used as service for live-video such as news, sports broadcasting image and movies in HYMANET. And this paper can minimize redundant multimedia streams that could appear when supporting multimedia service using multicast.

“…In this case, the APs generate their own AP_# only within AP_# fields. The IP address and AP_# assigned for the first time remain unchanged even though the MN travels among APs except the case that MN receives a MGA packet from the BMSA [5,6]. Thus, the two AP_#s of three AP_# fields are changed according to the MN's movement among APs.…”

“…For solving these problems, this paper adopts the multicast technique to reduce the number of channels of a server and the service delay. It also adopts handover mechanism using AP identification numbers (AP_#s) as the Internet Protocol (IP) header to prevent cutoff service and reconnection caused by the MNs' movement [6,7]. This paper uses the buffered multicasting/switching agent (BMSA) to perform multicast in WLAN.…”

This paper proposes the multicast system for seamless live multimedia in a wireless network. The multicast technique for live multimedia and a part of handover mechanism are performed on the buffered multicasting/ switching agent (BMSA) in a wireless local area network (WLAN). The rest of the handover mechanism is performed on access points (APs). This paper uses a new Internet Protocol (IP) header that is composed of three AP numbers (AP_#s) and 1-bit overwrite bit (OB) to perform seamless service. The three AP_#s support a smooth handover for solving the cutoff service when mobile nodes (MNs) move among other APs in WLAN. The overhead for a new IP header (2 bytes long) is negligible in comparison with multimedia service, and the overhead for the multicast group address (MGA) packet that is used in the transmission of MGA is only 11 bits. The MGA packet is composed of two AP_#s, an overwriting group address (OGA) bit, and MGA. We confirmed that the proposed multicast system can decrease the number of channels required, the delay of service, and the possibility of packet duplication because multicast is not provided on the multimedia server but on the BMSA in WLAN.
