Study of Improved Mobile IPv6 Protocol

Compared with Mobile IPv4, Mobile IPv6 has many advantages. It is more powerful and safe, which will play an important role in the future mobile network. However, when mobile nodes hand over frequently, the standard Mobile IPv6 protocol will result in vast location updates and the latency of registration, as well as degradation of network performance. Therefore the standard Mobile IPv6 must be improved to adaptive this situation. In this paper, three improved protocols are introduced and deeply analyzed.
