Problems solved by technology

On the one hand, each layer in the protocol entity uses its own local information and decision variables to obtain independent performance optimization of each layer, so the global optimization of the network on the existing layered mechanism can only be achieved by adjusting the independent management and control mechanism of each layer , so the implementation mechanism is relatively complex, and it is difficult to achieve the ideal network performance optimization performance goal in the control system
On the other hand, the network designed based on the OSI model has the advantages of being scalable and easy to implement, but it has low efficiency in using network resources, lacks fairness, and has weak network manageability.

Embodiment Construction

[0033] Aiming at the problem of low network reliability under the condition of mixed service transmission, the present invention provides a method for improving network transmission efficiency under the condition of ensuring link reliability, and realizes high efficiency of network resources under the condition of ensuring high reliability of the transmission link Adaptive adjustment of utilization and transmission rate ensures reliable transmission of mixed services.

[0034] To achieve the above object, the technical scheme of the present invention is as follows:

[0035] 1. Set up a comprehensive optimization model for link reliability and network performance, using the following sub-steps:

[0036] a. Optimization of resource utilization and link usage cost at the sending end

[0037] maximize[U s (x s ,ρ s )-λ s (t)x s -μ s (t)ρ s ]

[0038]

[0039] in Use a cost update mechanism for the link, λ s (t) is the network congestion cost of using the link L(s) to...

Abstract

The invention provides a method for improving the network transmission performance under a condition of ensuring link reliability. Through steps of setting a link reliability and network performance comprehensive optimization model and decomposing the link reliability and network performance comprehensive optimization model to obtain an optimal engineering solution, and establishing a transmission rate adaptive control mechanism, and the like, high-efficiency utilization of network resources and adaptive control of a transmission rate are realized under a condition of ensuring high reliability of a transmission link, and reliable transmission of a hybrid service is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to wireless network and optimization. Background technique [0002] With the rapid development of network technology, wireless communication networks not only provide users with traditional voice services, but also provide users with mixed services such as data transmission and web browsing. Different services have different requirements on quality of service such as bit error rate, delay, and jitter. The services of the wireless communication network can be divided into two categories according to the timeliness of transmission: one is real-time services such as voice, video, etc. (the real-time requirements are strict, but a certain bit error rate can be tolerated); Data, etc. (the real-time requirement is not strict, but the bit error rate is higher). [0003] The transmission of mixed services requires not only high reliability of the transmission link, but also...
