Problems solved by technology

[0002] The disadvantages of static planning of wireless coverage areas include: when the network is large, static planning is time-consuming and labor-intensive; when the network changes (increase or decrease), re-planning and adjustment are required
However, the disadvantages of current dynamic planning include: the real-time change of the coverage area is not strong; the gateway is not considered, and the coverage area is not optimal in terms of system bandwidth; the gateway is not considered, and there is the possibility of isolated networks

Embodiment Construction

[0031] The invention dynamically plans the wireless coverage area according to information such as the degree of density of neighbors and the number of hops to the gateway, and dynamically adjusts the wireless coverage area of ​​the device in real time. Reduce the degree of wireless mutual interference of the entire wireless network system, and effectively improve the total bandwidth of the system.

[0032] When a node is powered on and enters the network, the first thing to do is to detect the surrounding nodes. Here, a passive broadcast detection method is adopted. The node broadcasts the detection message to the surroundings, allowing other nodes to detect the existence of the node. Nodes initially send detection messages with minimum power and maximum rate to detect their closest nodes and reduce interference to other nodes. When node A receives the detection message from node B, and node A thinks that it can hear the message clearly (currently judged by the signal-to-noi...

Abstract

The invention relates to a method for dynamic communication in a wireless coverage area, which comprises the steps of detecting communicating neighbors and gateway degree information of nodes, setting an initial transmission power and a transmission velocity, adjusting the coverage area and processing isolated cells, wherein the communicating nodes refers to nodes A and B which can receive detection reports mutually; and the isolated cells refers to cells which have the maximum gateway degree and no route to a gateway. Compared with the prior art, the method has the following advantages of realizing quick and effective dynamic planning of a wireless coverage range, introducing gateway information to aim the planning at increasing the total bandwidth of the system, increasing the processing of the isolated cells to reduce communication islands in a dynamic process, performing passive broadcast detection to reduce signaling interaction and acquire equivalent information and optimally ensuring the transmission velocity and high bandwidth in cell regulation.

Description

technical field [0001] The invention relates to the introduction of the breathing effect of the cell in the communication process of wlan equipment Ad-Hoc mode, and dynamically plans the wireless coverage area according to the information such as the density of neighbors and the number of hops to the gateway, and especially relates to a wireless coverage area method of dynamic communication. Background technique [0002] The disadvantages of static planning of wireless coverage areas include: when the network is large, static planning is time-consuming and labor-intensive; when the network changes (increase or decrease), re-planning and adjustment are required. However, the disadvantages of current dynamic planning include: the real-time change of the coverage area is not strong; the gateway is not considered, and the coverage area is not optimal in terms of system bandwidth; the gateway is not considered, and there is the possibility of isolated networks. When there are ma...
