Comparison of Mechanisms for Reducing Handover Latency and Packet Loss Problems of Route Optimization in MIPv6

In the last few years tremendous development in the area of wireless and mobile network has been observed. Internet Engineering Task Force (IETF) proposed Mobile IPv6 to provide mobility in wireless networks. In Mobile IPv6, a Mobile Node directly updates its current location information to a Correspondent Node using a Route optimization technique. However, Route Optimization suffers from handover delays derived from the signaling message exchange. Handover latency in Mobile IPv6 plays an important role in the performance of a network scenario. It results in packet losses and severe End-to-End performance degradation. This paper analyzes and also compares some of the existing mechanisms that are used for reducing handover latency and packet loss problem in the current mobile IPv6 Route Optimization environment and gives the overview of this area.
