Abstract

The invention relates to a maintenance method for neighborhood information of network nodes in wireless self-organizing network. The functions of neighborhood information updating parts of an MAC layer and a network layer are merged, the neighborhood information interaction process flow between the MAC layer and the network layer is specified, and the network communication efficiency is effectively improved.

Description

technical field The invention belongs to the field of wireless ad hoc network communication, and is an improvement based on the IEEE802.16d standard Mesh mode. Background technique The wireless ad hoc network is a highly flexible network, and an important manifestation of its flexibility is that the topological relationship of the nodes in the network is relatively complex, and there may be relatively frequent changes. This change in turn affects the interaction between nodes. For this reason, in order to ensure the normal progress of communication, each node must record and regularly update the situation of other nodes around the node, which is why the node maintains the neighbor list. In the original MAC layer and network layer, for different application purposes, two sets of neighbor node information need to be maintained. In the original MAC layer neighbor information maintenance method, the sending node sends a network configuration message (Network Configuration, N...
