Method for realizing wireless self-organizing network building based on collision detection and competitive mode

Abstract

The present invention relates to the wireless communication technology field, and discloses a method for realizing wireless self-organizing network building based on the collision detection and the competitive mode. The method concretely comprises the following processes: N wireless nodes are arranged in the network to monitor a communication channel and detect the usage condition of the channel, wherein N is a natural number of bigger than 1; when the wireless network nodes detect that the channel is idle, the node broadcast information is sent, the broadcast information of N-1 wireless network nodes except itself is received at the same time and is recorded; the steps 1-2 are repeatedly performed to complete the enumeration process until the network center nodes of the network are determined; the network center nodes employ the time division multiplexing mode to complete the interaction of resource distribution information; and the network center nodes and the N-1 wireless network nodes except itself complete the building of the network through the mode of the three times handshake interaction. The method for realizing the wireless self-organizing network building based on the collision detection and the competitive mode can adapt the conditions of the changeable wireless self-organizing network topology structure and the large number of the wireless network nodes to allow the detection coverage range of the wireless sensor to be widened.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for establishing a wireless ad hoc network based on conflict detection and competition. Background technique [0002] With the development of wireless sensor technology, wireless sensors have entered the fields of environmental monitoring, intelligent transportation, and battlefield detection with their convenient collection methods and low prices, and have become an important means of technical realization and driving force in the field of the Internet of Things. In the detection of environments that are not suitable for human survival, such as traditional harsh environments and damaging scenes, wireless sensors also play a huge role. [0003] However, with the limited detection coverage of a single wireless sensor, the traditional single-node acquisition and processing method of wireless sensors cannot meet the requirements. Through wireless sensor netw...
