Optimizing handover performance for heterogeneous wireless networks in pmipv6

K.Jaya Bharathy, A.Prithiviraj, Dr.K. Krishnamoorthy


In heterogeneous wireless environment, vertical handover is needed for supporting seamless mobility (i.e.) moving from one network to another network. Recently, a mobility management protocol called Proxy Mobile IPv6 (PMIPv6) is a Network based that has received much attention in Next generation IP mobile networks. PMIPv6 does not require a mobile node to participate in any of the mobility related signaling. During handover process in heterogeneous networks, a packet loss and handover latency problem occurred increasingly. However there are many existing methods to overcome these problems but still it’s a challenging task. The proposed work concentrate on PMIPv6 domain where the packet loss can be reduced by buffering scheme at MAG’s and the handover process is made rapidly by moving the data between two MAGs so that the latency will be reduced. Moreover the False Handover Initialization will be avoided by multicasting the data packets to both previous and new access devices where the out-of-packet sequence problem also reduced.

Keywords: PMIPv6, vertical handover, packet loss, latency, Multicast, Heterogeneous network.
