Problems solved by technology

Before the new care-of address can be used, the communication between the mobile node and the correspondent end will be interrupted, so the DAD process will cause a large handover delay; (4) Binding Update process (BindingUpdate, hereinafter referred to as BU): new After the care-of address passes the uniqueness check, the mobile node sends BU messages to HA and CN

Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0061] The handover delay of mobile nodes is one of the most important reasons affecting real-time performance. The Layer 2 trigger (hereinafter referred to as L2) handover prediction mechanism used in the FMIPv6 handover method, on the one hand, can complete the care-of address configuration and duplicate address detection in the network layer handover process in advance, thereby effectively reducing the handover delay; The inaccurate prediction time leads to false reporting of L2 triggering, resulting in additional handover delay overhead and affecting handover efficiency. In fact, the mobile trajectory data of mobile nodes is often periodic. The low-consumption Apriori algorithm proposed in this embodiment is especially suitable for such highly correlated data, and can mine highly relevant movement rules from the mobile trajectory data set....

Abstract

The present invention relates to a low-consumed FMIPv6 switching method on the basis of mobile predication. A low-consumed Apriori method is employed to predicate the mobile locus of a mobile node and take the place of the L2Handover switching protocol in the FMIPv6 so as to eliminate the negative impacts of the L2Handover switching; the time attribute and the space attribute of the mobile locus of the mobile node are taken as excavation object data, and the dual attributes of time and space of the mobile locus are fully considered; and the scanning range of the data set of the mobile locus is reduced and the time of obtaining a candidate item set is minimized in the process of generation of a frequent item set through the candidate item set so that the purpose of low consumption is achieved. Compared with a traditional FMIPv6 switching method, the low-consumed FMIPv6 switching method on the basis of mobile predication is more suitable for realization on a mobile terminal with limited resource.

Description

technical field [0001] The invention relates to a low-consumption FMIPv6 switching method based on movement prediction. Background technique [0002] The vigorous development of mobile Internet has also promoted the construction boom of WIFI access hotspots in the world. However, the handover delay of the mobile node between two wireless APs cannot meet the performance requirements of apps with high real-time requirements such as Internet telephony. In order to realize the seamless switching of mobile devices and provide users with a better wireless Internet experience, IETF has formulated a network transmission protocol that can solve the problem of IP mobility—Mobile IPv6 (MobileIPv6) protocol, which can make mobile devices no matter where they are Where the IPv6 network can always communicate with the communication nodes continuously. The following technical terms and abbreviations are mainly involved in the Mobile IPv6 protocol: [0003] (1), Mobile Node (MobileNode, ...
