Embodiment Construction
[0036]The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0037] The technical scheme of the present invention relies on the optimized 6LoWPAN network neighbor discovery process, realizes an effective node access control scheme, and provides security protection for the network. In the 6LoWPAN network, the border router plays an important role. In addition to connecting the WSN network to the Internet, it is also responsible for notifying the link prefix (subnet information) route and other configuration information, and maintaining the IPv6 address of each node within the network range. information and MAC information, so that it can perform two-layer address resolution and duplicate address detection. The border router needs to be manually configured, such as figure 1 shown.
[0038] Internet Protocol Version 6 (IPV6) Neighbor Discovery is a set of messages and procedures defined in RFC4861 for dete...
