Mobile IPv6 allows mobile devices always addressable by its home address wherever it is located. Previous research has shown that MIPv6 only defines a means of managing global mobility (macro-mobility) but does not address local mobility (micro-mobility) separately. Instead, it uses the same mechanism in both cases. This involves long handover delay and a lot of signaling. In this thesis, focus is given on a micro-mobility based test-bed evaluation experiment with improved handover scheme. This proposed handover scheme is the enhancement of the existing Mobile IPv6 protocol, it integrates hierarchical concept and multicast function. Hierarchical design was used to totally shield the micro mobility from macro mobility in order to reduce location update signal and signaling traffic within micro level network while multicasting is used to send packets to Mobile Node (MN) through base stations that are near to MN. This will reduce handover delay that causes packet lost when MN is roaming. The test-bed is comprised of hardware and software and network analyzer tool to monitor the handover operation. The hardware consists of 5 personal computers to perform the job of one Multicast Router (MR), 2 Access Points (AP), one Home Agent (HA) and one Correspondent Node (CN). A notebook is used as the Mobile Node (MN) This test-bed is used to analyze the Mobile IPv6 handover delay, packet delay and packet loss in real wireless environment. Since results were gathered from real environment, so wired and wireless media delay were taken into account in our performance evaluation entities. Prior to the test-bed performance measurement, time synchronization of CN (packet generator) and MN (packet receiver) is done with Network Time Protocol (NTP) to ensure the accuracy of the collected data. Two scenarios were measured, which are Mobile IPv6 handover and Enhanced Mobile IPv6 with multicast function and hierarchical design respectively. Finally, it was shown that the proposed handover scheme reduces the handover delay, packet delay, packet lost and increases the throughput and overall throughput during handover. This gives advantages of zero packet lost and lower handover delay which can significantly improve micro mobility performance on 3rd and 4th Generation mobile telephony and beyond.
