Problems solved by technology

The utilization rate of the communication channel of this method is not high, that is to say, the channel is far from being filled with data bits, which has a long transmission delay and brings large communication overhead and communication energy consumption. When it is poor, it consumes a lot of energy, speeds up the energy consumption of network nodes, and shortens the survival time of network nodes

Embodiment Construction

[0060] Embodiments of the present invention provide a fault-tolerant method for message transmission of a network node and a network node. After receiving a message segment sent by a sending end, the network node determines the message segment containing an error, and determines to perform data processing on the correct message segment. After the connection, due to the vacant position formed by the lack of message segments, the complete message can be formed by matching the erroneous message segment with the vacant position, and no retransmission is required, which improves the communication efficiency of network nodes and reduces network traffic. Communication energy consumption of nodes.

[0061] Such as figure 1 As shown, the error-tolerant method for message transmission of the network node provided by the embodiment of the present invention includes:

[0062] Step S101, receiving the message segment sent by the sending end, and determining the error-containing message se...

Abstract

Disclosed are a fault tolerant method for packet transmission of a network node and a network node, which relate to the communications technologies. A network node receives a packet segment sent by a transmit end, determines a fault-containing packet segment in the packet segment, determines a vacant position formed from a missing packet segment after data connection to a correct packet segment, and matches the fault-containing packet segment and the vacant position to form a complete packet without needing retransmission, so that efficiency of communication of a network node is improved, and energy consumption of communication of a network node is reduced.

Description

technical field [0001] The invention relates to communication technology, in particular to a fault-tolerant method for message transmission of a network node and the network node. Background technique [0002] A new type of network node such as a wireless sensor network is usually powered by a battery. When the battery is exhausted, the network node will fail, so it is necessary to save power consumption as much as possible. At the same time, in order to save power consumption, the network data of this network node may be reduced. Transmission reliability, so it is necessary to improve the fault tolerance of such network nodes. [0003] There is a big difference between wireless sensor network and wireless communication network. The main function of wireless communication network is to provide network interconnection, intercommunication and interoperability, and to provide correct and reliable transmission of data, while wireless sensor network is based on data collection, p...
