Wireless network node neutral access dynamic configuration method

Abstract

The invention discloses a wireless network node neutral access dynamic configuration method. The method comprises the following steps of conducting network synchronization of master and slave nodes, conducting preprocessing, reserving the application and reply, dynamically completing time slots, and conducting channel renewing and multiplexing based on priority decisions, and conducting data transmission. According to the wireless network node neutral access dynamic configuration method, the time slot utilization rate is high, the topology adaptation is good, the control overhead is small, the network opening time is short, and the network restructuring ability is strong.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a wireless network node random access dynamic configuration method with high time slot utilization rate, good topology adaptability and small control overhead. Background technique [0002] Wireless multi-hop ad-hoc communication equipment has many network parameters, complicated settings, long setup time, poor reorganization ability, too many manual setting operations, and cannot adapt to the dynamic network topology structure of mobile wireless network nodes that change according to tasks. Access and quick deployment capabilities. One of the most important and difficult issues in the research of wireless ad hoc network random access is how to dynamically coordinate and allocate communication subnet resource usage rights. [0003] TDMA (Time Division Multiple Address, time division multiple access) time division multiple access does not require complex coding, hi...

Problems solved by technology

[0014] 1. The main time slot of the network access node and the node number are fixedly allocated in a bundled manner. The number of time slots in each subframe is proportional to the size of the node. The update of the time slot list does not depend on topology changes. If there are more nodes, P-TDMA will stage will generate a large protocol overhead, which will degrade the protocol performance and limit the network scale;

[0015] 2. Each node holds an N×N priority list, which specifies the priority of each node for each time slot in advance. This is a completely fixed priority allocation method, and it is impossible to dynamically adjust the time slot according to the node business situation. priority of

[0016] Therefore, the existing wireless multi-hop mobile network channel reservation and time slot address allocation methods, while improving time slot utilization and topology adaptability, often at the cost of increased control overhead, resulting in too complex protocols and difficult to adapt to wireless communication networking The complex electromagnetic environment and the dynamic and changeable network topology cannot meet the requirements of rapid network deployment, real-time deployment, and efficient reorganization under the premise that the current wireless communication equipment has many parameters and complex settings.
