Searching and balance idea based industrial wireless network communication resource distributing method

Abstract

The invention relates to a searching and balance idea based industrial wireless network communication resource distributing method. The method comprises the following steps that: network equipment initiates an end-to-end communication resource application to a network manager; a routing calculation module calculates a path of the network equipment of the communication resource application, and submits the path calculating result to a communication resource distribution module; a communication resource distribution module calculates communication resource required by the path which is submitted by the routing calculation module; the communication resource fulfilling the requirement is searched according to a policy if idle communication resources fulfill the requirement on the number of the communication resource; the communication resource distribution module pre-distributes resources according to the path information submitted by the routing calculation module; a time slot distribution table is modified or updated if pre-distribution succeeds; and the distribution is completed if the distribution this time is finished. The method is easy to realize optimized distribution of the whole network communication resources, ensures network energy balance and real time of data transmission, reduces energy consumption of the whole network, and improves the network reliability.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to an industrial wireless network communication resource allocation method based on the idea of ​​search and balance. Background technique [0002] In recent years, with the rapid development of microprocessor technology and low-energy wireless communication technology, wireless network technology, which has been successful in the commercial field, has begun to enter the field of industrial control and become a new growth point for industrial automation products in the future. Obviously, in terms of configuration, installation, modification and expansion, the cost of wireless networks is lower than that of wired networks; moreover, compared with star and tree topologies, industrial wireless networks using mesh topologies have high flexibility and high reliability performance, high scalability, greater throughput and better balance of network energy consumption...
