摘要

Mobile IPv6 allows mobile devices always addressable by its home address wherever it is located. In this paper the focus is given on a micro-mobility based test-bed development with improved scheme. The test-bed consists of both hardware and software including four personal computers and one laptop. The laptop is used as Mobile Node (MN), two personal computers are functioned as access points, one personal computer as Home Agent (HA) and the other one is used as Foreign Multicast Router (MR). This test-bed is used to analyze the Mobile IPv6 handover delay, packet delay and packet loss in real wireless environment. We measured two scenarios those are Mobile IPv6 handover and Enhanced Mobile IPv6 with multicast function and hierarchical design. Finally, it is concluded that the proposed handover scheme reduces the handover delay from 4.4s to 0.2s, packet delay from 0.7s to 0.109s and from 44 packet loss to zero packet loss during handover. This gives advantages of zero packet loss and lower handover delay which can significantly improve micro mobility performance 3rd and 4th Generation mobile telephone technology and for beyond.
