Abstract

The invention discloses a routing method of a time division multiple access (TDMA) self-organizing network. The method comprises steps that during network initiation, each node acquires a fixed emission time slot in a competition mode, and the nodes acquiring the fixed emission time slots form a self-organizing network, and a multi-hop neighbor node table is established; when a communication instruction is detected, the node sending the communication information is taken as a source node, the node receiving the communication information is taken as a target node, and a transmission path from the source node to the target node is determined according to the multi-hop neighbor node table; when the transmission path is a first hop, the communication information is directly sent from the fixed emission time slot of the source node to the target node; when the transmission path surpasses one hop, the communication information is sent from the fixed emission time slot of the source node to the target node through a relay node. The invention further discloses a routing device of the time division multiple access (TDMA) self-organizing network. The method is advantaged in that network establishment and communication information transmission are specifically optimized, and the network is made to have organization property and high transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a routing method and device for a time-division multiple access self-organizing network. Background technique [0002] Ad hoc network is a combination of mobile communication and computer network. It is a kind of mobile computer network. User terminals can move freely in the network and maintain communication. There are currently two types of wireless mobile networks: the first is a network based on network infrastructure, and a typical application of this network is a wireless local area network. The second type is a network without network infrastructure, which is generally called an ad hoc network. There is no fixed router in this network, and the nodes in the network can move freely and communicate with each other in any way. Each node can realize the function of router to search and maintain the route to another node in the network. The self-organizing network ...
