Method and device for network link management

Abstract

The invention discloses a method,a device and a network system for network link management. The method includes that get the link access information of a target link, wherein, the link access information is used for indicating if a target node can transmit data in the target link; get the state of the network that the target link belongs to, wherein, the network state is used for indicating if the transmission power of each link in the network is less than the alarm transmission power; adjust the transmission power of the target node in the target link according to the link access informationand the state of the network that the target link belongs to. The proposal provided by the embodiment of the invention can help optimize the number of the accessed links on premise of ensuring the present signal to interference plus noise ratio (SINR) of each link to be not less than the preset least signal to interference plus noise ratio (SINR).

Description

technical field [0001] The invention relates to a communication neighborhood, in particular to a network link management method and device. Background technique [0002] Different from the cellular network, the Ad-Hoc network is a wireless network established on a specific occasion, which is composed of a router (Router) and a host, and these constituent nodes can move positions arbitrarily. The most notable features of this network different from existing wireless networks are autonomy and multi-hop. Self-government means that there is no central management node, such as a base station, in the Ad-Hoc network, and all nodes are in an equal position. All management functions such as resource allocation, routing management, etc. are coordinated and shared by all nodes. Multi-hop means that the communication distance of the Ad Hoc network is much greater than the effective wireless connection distance, that is, forwarding and routing are required. It can provide more flexibl...

Problems solved by technology

However, in the actual network, the Pareto optimal condition cannot be satisfied, so during the access process, as the link power increases, some links that have already met the QoS may no longer meet the QoS requirements due to power constraints.

[0011] That is to say, in all the link access control algorithms mentioned above, under the premise of providing protection for the QoS of the accessed links, the number of access links in the system cannot be maximized, resulting in a waste of system resources
