Embodiment Construction

[0046] The specific implementation manner of the present invention will be described in more detail below with reference to schematic diagrams. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0047] An embodiment of the present invention provides a routing method for a D2D ad hoc network. Any two D2D terminal devices in a cell can establish a routing connection through a control center in the cell. That is, when any two of the plurality of D2D terminal devices belonging to the control center need to establish data transmission, they only need to initiate a request to the control center, and the control center can calculate the routing path, and notify the next-hop node of each D2D terminal device in ...

Abstract

The invention provides a D2D Ad-Hoc network routing method and a D2D Ad-Hoc network routing system, wherein a routing connection can be established between any two D2D terminal devices in a cell through a control center in the cell. Resource of the control center is fully used, a plurality of the D2D terminal devices in the cell are free from establishing a routing path through fussy routing inquiry broadcasting, thus, a substantial amount of information interaction for creating a routing table between the D2D terminal devices is avoided, time delay is reduced consequently, a data transmissionspeed is improved, and simultaneously, electricity consumption of the D2D terminal devices is also reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a D2D ad hoc network routing method and system. Background technique [0002] The routing algorithm is a key technology in the Mesh form ad hoc network. Since the devices in the Mesh form ad hoc network are basically equal and there is no central control node, the routing algorithm is basically based on the distributed broadcast response method. The general method is : A node initiates a routing request to all neighboring nodes around it, and the neighboring nodes that have established a valid routing table leading to the destination node respond as the next hop, and the neighboring nodes that have not yet established a valid routing table leading to the target node continue to use The routing request is forwarded in broadcast mode. Typical ad hoc network routing algorithms based on this approach, such as AODV, DSR, DSDV. [0003] The disadvantage of the distribute...
