Embodiment Construction

[0055] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0056] figure 1 It is a functional block diagram of the routing method of the wireless ad hoc network provided by the embodiment of the present invention, such as figure 1 As shown, the steps include:

[0057] Step S101: The current node obtains the topology information of the fisheye domain of the wireless ad hoc network where the current node is located by exchanging node information with other nodes.

[0058] For any node, when the node is powered on and broadcasts a broadcast message with a sequence number of 1, only the information of the node is included in the broadcast message. Through node information interaction, when a node sends subsequent b...

Abstract

The invention discloses a routing method and device for a wireless ad hoc network, and relates to the field of LTE and wireless mobile ad hoc networks. The method includes the following steps: a current node obtains topological information of a wireless ad hoc network fisheye domain where the current node is through interaction of node information with other nodes; according to the obtained topological information of the fisheye domain, nodes in the fisheye domain are elected as base station mode nodes or terminal mode nodes; according to the current node and the type of a one-hop neighbor node of the current node, generating a link state table; and according to the link state table, generating a routing list with the current node being a root node. Through the routing method and device provided by the invention, realizes application of an existing LTE technology to the wireless ad hoc network, and better adapts to rapid change of network topology, thereby improving routing precision, and saving routing overhead.

Description

technical field [0001] The present invention relates to the fields of The 4th Generation Mobile Communication (4G) Long Term Evolution (LTE) and wireless mobile ad hoc networks, in particular to a routing method and device for wireless ad hoc networks. Background technique [0002] Ad hoc network communication technology is a mobile communication technology that can quickly and automatically form a network. It is different from a general centered, centralized control network that relies on pre-deployed communication infrastructure. It has rapid deployment and does not rely on basic communication facilities. , Self-maintenance, self-management, strong invulnerability, etc. The nodes in the network not only have the functions of ordinary mobile terminals, but also have routing functions. The communication of the network depends on the mutual cooperation, self-organization and self-operation between nodes, and jointly Communication tasks; have been widely used in emergency comm...
