Multicast based and fast handover scheme in mobile IPv6 wireless network

The main goal of mobile IPv6 is that a mobile node is always addressable by its home address, whether it is currently attached to its home link or is away from home. Mobile IPv6 enables applications running on an Internet node to survive physical reconnection by inserting a few additional features at the network layer. In this paper, focus is given to a micro-mobility based test-bed development with improved algorithm. The test-bed consists of both hardware and software, including four PCs and one laptop. The laptop is used as mobile host (MH), two PCs act as access points, one PC becomes the home agent (HA) and one PC is used as a multicast router (ML). This test-bed is used to verify the theoretical enhancement of the micro-mobility handover algorithm via the results (packet loss, handover delay and quality of service). There is no signaling traffic overload between the MH, HA and correspondent host (CH), the handover delay is low, approximately below 10 ms, and the video stream has good reception.
