Embodiment Construction

[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] The invention discloses a content-centric network-based routing method on a hierarchical topological structure graph, adopts a method of sharing routing information with some nodes, flattens the information required for this routing to some nodes, and then only needs to provide These nodes that share the routing information are all that is needed, so that the routing information carried in the message can be greatly reduced, and the purpose of efficient routing can be achieved. Moreover, message communication adopts the CCN (Content-Centric Network) protocol for the Internet of Things. This protocol is content-centric, uses names to name content, and can implement name-based routing. Th...

Abstract

The invention provides a routing method based on a content center network on a hierarchical topology structure chart. The routing method comprises the following steps: (1) establishing routing information of aggregation points on a hierarchical chart, wherein each aggregation point maintains the reachable routing information between two nodes; and (2) adopting interest and content message types in a CCN protocol and PIT and FIB to realize name-based routing forwarding between arbitrary two nodes in the network. According to the routing method provided by the invention, a part of nodes share the routing information to share the necessary information of the routing with a part of nodes, then a message packet only contains these nodes that share the routing information, so that the routing information carried in the message is greatly reduced to achieve efficient routing. The protocol occupancy space is greatly reduced, and services and corresponding data in the network can be identified and expanded by the names, thereby being very convenient and flexible, and all these makes the CCN be more suitable for the content-oriented network, namely the internet of things.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a content-centric network-based routing method on a hierarchical topology graph. Background technique [0002] The routing technologies on the existing large-scale wireless sensor autonomous network mainly include Zigbee and RPL, two mainstream standards and protocols. Although the network that Zigbee can form is flexible, the networking is relatively simple, and the protocol is too complicated to achieve lightweight implementation. For this reason, Zigbee is relatively widely used in small-scale networks, but rarely used in large-scale networks. trace. RPL is a routing networking protocol for 6LowPAN. It is currently a widely accepted routing protocol in the Internet of Things. Its basic idea is to construct a tree structure with the terminal as the root node. The root node owns the entire network topology structure. The access of two nodes in the tree networ...
