Embodiment Construction

[0018] The present invention will be described in detail below with reference to the embodiments.

[0019] The multi-path data flow distribution routing method MDFD (Multi-path Data FlowDistribution) of the present invention.

[0020] In order to make the wireless sensor network achieve the purpose of high efficiency and energy saving, the present invention uses the method of MDFD data flow distribution to balance the energy consumption of network nodes, so that all network nodes can maintain stable energy consumption, and the network scale can basically be maintained within the life cycle. constant.

[0021] In order for sensor nodes to save computational overhead when selecting an appropriate path, MDFD uses reliability evaluation parameters to select an appropriate path. represents any node, each The nodes are all adjacent to node a, Table 1 is Each parameter of the node:

Abstract

The invention provides a wireless sensor network data flow rate shunting routing method based on multipath, and relates to a wireless sensor network technology method. According to the method, an MDFD data flow rate shunting method is used for balancing the energy consumption of network nodes, so that all network nodes can maintain the balanced energy consumption, so that the network scales can basically maintain unchanged in the survival period; in order to save the calculation expenditure of sensor nodes during the proper path selection, the MDFD uses the reliability evaluation parameter for selecting the proper path; the node state information is used for calculating the reliability evaluation value of the single node; when the node rest energy is considered, only the nodes being about to take part in the next hop of routing campaign are considered. The method has the advantages that the energy consumption problem of the wireless sensor nodes can be effectively solved; the life period of a wireless sensor network can be effectively prolonged; the condition of work resistance of the wireless sensor network caused by the energy consumption problem is relieved.

Description

technical field [0001] The invention relates to a wireless sensor network technology method, in particular to a multipath-based wireless sensor network data traffic distribution routing method. Background technique [0002] Today, with the rapid development of wireless sensor networks, wireless sensor networks are widely used in various fields of society, and the problems of wireless sensor networks are becoming increasingly prominent. Because the working environment of wireless sensor network is very complex, in addition, the limited energy of wireless sensor network nodes, limited hardware resources such as bandwidth and storage are factors that limit whether wireless sensor nodes can work normally. Especially the energy consumption of sensor nodes, because the energy consumption of wireless communication nodes in wireless sensor networks is determined by the energy of batteries, and the working environment of wireless sensor networks determines that it cannot replace batt...
