Problems solved by technology

For multiple types of packets (different lifetimes and different packet sizes), they cannot solve the problem of multipoint wireless resource allocation
They aim to optimize wireless resource allocation to maximize immediate utility. However, in the case of unknown system dynamics, current decisions will have an impact on the future. These studies ignore this impact, so they aim to maximize immediate utility. decisions are short-sighted
Some of them focus on single-user wireless resource allocation schemes, while ignoring the wireless resource allocation of all users in the network. When the number of nodes in the network gradually increases, it will face the problem of excessive mechanism complexity.

Embodiment 1

[0053] to combine figure 1 , the present invention mentions a resource allocation method suitable for wireless networks, the resource allocation method includes:

[0054] S101. Obtain the priority information of data packets in the cache of network nodes and the information of available carrier resources in the system, and perform centralized carrier resource allocation to nodes in the network based on the principle of matching services with resources.

[0055] In this embodiment, for the priority of the data packets in the cache of the network node, the priority is jointly determined by the remaining lifetime of the corresponding data packets and the size of the data packets, and obtaining carrier resource information available in the system requires first obtaining Corresponding carrier power gains, and then sort all the carrier power gains; further, according to the priority of all data packets and the sorted carrier resource information, the carrier resource allocation is ...

[0062] to combine image 3 , the entire process of the resource allocation method suitable for wireless networks mentioned in the present invention is:

[0063] S301. Determine the available carrier set H in the system, the number K of nodes and the total number M of data packets to be sent.

[0064] S302. Obtain the priority information of the data packets in the data cache of each node. The priority of the data packets can be represented by the product of the size of the unsent data and the reciprocal of the remaining survival time; at the same time, the available carriers in the carrier set are calculated according to the carrier power Gains are reordered from largest to smallest.

[0065] S303. A data packet with a higher priority represents that among all data packets, the data packet needs to be transmitted as soon as possible, so the data packet will be allocated a better carrier resource, and a data packet with a smaller priority represents that among all data packets...

Abstract

The invention discloses a resource allocation method suitable for a wireless network, which includes: obtaining priority information of data packets in the cache of network nodes and information of available carrier resources in the system, and performing a process on the nodes in the network based on the principle of matching services and resources. Centralized carrier resource allocation; according to the carrier resource allocation results of the nodes in the network, perform predictive distributed transmission power resource allocation to the nodes in the network, and iterate until convergence; according to the carrier resources and transmission power resources of the nodes in the network The allocation result of the system is updated. The present invention can effectively reduce the accumulation of data packets with urgent transmission requirements in the data cache in the nodes and minimize the use of transmission power resources in the face of multiple network nodes, multiple types of data packets, and unknown system dynamic characteristics.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method, device and system suitable for wireless networks. Background technique [0002] With the rapid development of wireless networks, users' main business has changed from voice communication to multimedia services such as video information. The rapid development of wireless networks has also brought many problems, such as the rapid increase in the number of nodes in the network, the rapid increase in the number of data packets that need to be transmitted in the data cache of the nodes, and the types of data packets are gradually diversified. How to correctly allocate carrier resources and use less transmission power resources to transmit data packets to be sent in the node cache is an urgent problem to be solved. [0003] However, most of the existing studies have many problems. For multiple types of packets (different lifetimes and diff...
