Abstract
Problem statement: In the previous researches, steps were taken to resolve the problems of multicasting, after several discussions. Actually these issues were raised, while multicasting packets from Internet Protocol (IP) to Mobile Nodes (MN). On the other hand, there is very little concern about the problem of packet loss reduction. Sometimes the occurrence of multicast service chaos is ignored during handovers. Therefore in this study it has been tried to explain the optimal multicast technique for Mobile IPv6 (MIPv6) to diminish the required amendment to the existing fast handover. Approach: An alternate method is suggested in Fast handover for MIPv6 (FMIPv6) to lessen the packet losses during handovers, before tunneling. Based on the qualities of the multicast subscription techniques for the Mobile IPv6 (MIPv6), multicast upholds method for FMIPv6. MIPv6 in general comprise two types of multicasting techniques, which are related to Home Agent (HA) and Foreign Agent (FA). These techniques help the MN to obtain the packets in roaming location referred as Foreign Network (FN), which is being forwarded by the Core Network (CN). But due to the handover latency problem MN have to experience packet loss while switching between any two Access Routers (AR). A protocol has been designed to conquer the issue of packet loss in MIPv6. Results and Conclusion: This protocol can be used during joining process in MIPv6 before tunneling to eliminate the IP connectivity time. This implementation allows a mobile node to be connected more quickly at a fresh point of connection, when that mobile node moves with less packet losses.

In networking, Multicast (Paul, 1998; Gattupalli and Krishna, 2010) is a way to deliver information to aFrom the previous century to the present, a huge range of wireless technologies has resulted in a rapid growth of wireless connections like Satellite and WiMAX and Mobile technologies like Bluetooth, WiFi (Kwon et al, 2008)
In FMIPv6 when Mobile-initiated Handover (MH) is connected to the New AR (NAR), mobile node has to get hold of a new Care of Address (CoA) (Kwon et al, 2008)
After confirming from the NAR about MH information, it will send NAR Handover Initiate interruption period occurring during FMIPv6 handover is based on multicast subscription methods (Kwon et al, 2008)
Summary
Multicast (Paul, 1998; Gattupalli and Krishna, 2010) is a way to deliver information to aFrom the previous century to the present, a huge range of wireless technologies has resulted in a rapid growth of wireless connections like Satellite and WiMAX and Mobile technologies like Bluetooth, WiFi (Kwon et al, 2008). In IP-based wireless networks (Krishna et al, 2009a; Pack and Choi, 2003), handover latency is one of the important problems to reduce time period. There is a possibility of connection switching delay as well as consideration of IP protocol operation, occurring during the handover. Handover latency occurs when there is lacking ability to send or receive packets to and from the mobile host.
