A survey of enhanced hierarchical MIPv6

In wireless communication, the users can communicate well when the mobile node is static. However, if the mobile node is moving from one base station to one base station during the communication, distortion or disconnection may happen because the mobile node needs to handover from one base station to another. Having known this issue, this paper presents the studies that have been carried out which aims to enhance the handover performance. In order to achieve the aim, a load balancing mobility management scheme and a topology learning mobility management scheme for HMIPv6 are being proposed. We believe that these mobility management schemes are able to improve the handover performance of HMIPv6. This method is believed to be able to provide better service quality to the wireless Internet user.
