Method for guaranteeing transmission quality of security monitoring data in wireless local area network

Abstract

The invention discloses a method for guaranteeing the transmission quality of security monitoring data in a wireless local area network, belonging to the wireless security monitoring field. The methodof the invention comprises the following steps: 1) wireless nodes register at the access point of the wireless device and provide the configuration information containing the priority of the wirelessnodes to the access point of the wireless device; 2) the access point of the wireless device initializes the bandwidth of each wireless node; 3) access point of the wireless device monitors the communication bandwidth of the wireless nodes and the uplink bandwidth of the access point and judges whether the uplink bandwidth is sufficient or not according to the monitoring result; 4) if not, the bandwidth allocation is performed according to the priority of the wireless nodes; and 5) the wireless nodes automatically regulate the data stream according to the obtained bandwidths. Compared with the prior art, the method of the invention optimizes the network resource, reduces the delay and packet loss rate of data transmission and greatly improves the transmission quality of security monitoring data.

Description

Technical field [0001] The invention relates to a method for ensuring the transmission quality of security monitoring data, in particular to a method for ensuring the transmission quality of security monitoring data in a wireless local area network, and belongs to the field of wireless security monitoring. Background technique [0002] With the further popularization of wireless networks, the application of security monitoring systems based on wireless networks has become more and more widespread. Security monitoring data transmission usually has bandwidth, time delay and data loss rate requirements, but the current wireless network with its own uneven bandwidth does not provide the necessary data transmission quality adjustment mechanism for this. It is embodied in the following aspects: [0003] 1. Network bandwidth, that is, the amount of data that the network can transmit per second. The greater the bandwidth, the more data can be transferred. Although the bandwidth of the c...

[0005] 3. The bandwidth of each node of the wireless network based on contention access using DCF cannot be precisely controlled, and different network topologies have a great impact on the network bandwidth, resulting in a wide gap in the bandwidth of each node, and the topology of the wireless security monitoring network depends on specific requirements. Decisions are made in various forms, so the traditional wireless control strategy is not suitable for the engineering implementation of wireless security

[0006] 4. The wireless communication bandwidth is unstable, and the traditional device control strategy cannot intelligently adjust the data communication volume. When the data volume is too large, there will be congestion, flow interruption or packet loss
