Embodiment Construction

[0078] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0079] In the two-layer congestion control method of the wireless network of the present invention, when the current network node detects that its own congestion occurs, it sends congestion control information including its own congestion situation to the network node connected to itself. In this way, the network node receiving the congestion control information can adjust the transmission rate of the local node according to the congestion situation contained therein, thereby realizing congestion control.

[0080] The wireless network congestion control method of the present invention can be directly applied to actual networks, such as wireless multi-hop networks including wireless mesh networks, mobile Ad hoc networks and wireless sensor networks, there...

Abstract

The invention discloses a two-layer block control method of wireless network, comprising that A, current network node detects self block condition and executes step B when in block, B, current network blocked node sends a block control message with self block condition to connected an ascending network node or a nearby node, C, the network node receiving the block control message, according to the block condition adjusts local node transmission speed. The invention makes clear block detection, message sending, and block control, to be directly used in real network, as wireless multi-jump network which comprises wireless network, mobile Ad hoc network and wireless sensor network or the like, thereby reducing local block.

Description

technical field [0001] The invention relates to the data transmission technology of the wireless network, in particular to a two-layer congestion control method of the wireless network. Background technique [0002] In a classic computer network, end-to-end flow control is usually implemented at the upper layer of the network, for example, the TCP congestion control mechanism is used to implement an end-to-end flow control mechanism. This end-to-end flow control mechanism cannot solve the local congestion problem of the wireless network well. [0003] Specifically, adjacent hops in a wireless mesh (Mesh) network share media resources, so how to schedule these adjacent links in a wireless mesh network to maximize network throughput is crucial. The loss of data packets in a wired network is caused by network congestion; while in a wireless network, due to the interference of the transmission channel, the bit error rate of network transmission is high, and random data packet l...
