Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] An embodiment of the present invention is a design method for a low-power wireless sensor network based on self-powered technology, specifically:

[0028] Design network architecture: Combining the characteristics of plane topology and hierarchical topology, a layered and distributed network architecture is proposed, such as figure 1 As shown, the network architecture divides wireless nodes into multiple subnets. The number of subnets and the number of nodes accommodated in each subnet can be changed dynamically. The network architecture has dynamic scalability and is a layered network that supports node density adaptation. Network Architecture. The nodes in each subnet form a flat peer-to-peer mesh network, and each node in the network can be used as a routing node. The network has nodes and backup nodes with different identities (diff...

Abstract

The invention provides a low power consumption wireless sensor network design method based on the self-powered technology. The specific process is as follows: dividing wireless nodes into multiple subnets, and forming a planar peer-to-peer mesh network among the nodes in each subnet, for each subnet, after a stable cluster structure is formed according to routing rules of an LEACH protocol, collecting, by a cluster node, an information table of member nodes to construct a neural network; searching for samples matching cluster member information in a sample database for training, and obtainingneural network parameters of cluster members and the cluster node; sending, by the cluster member nodes, information subject to fusion processing to the cluster node according to the constructed neural network; performing, by the cluster node, fusion processing on the received information, and then transmitting a small number of feature values of reaction information to other subnets to perform further data fusion processing; and integrating interfaces of plurality of energy collection self-powered devices on the node.

Description

technical field [0001] The invention belongs to the technical field of wireless networks, in particular to a design method for a low-power wireless sensor network based on self-powered technology. Background technique [0002] When the wireless network is deployed in an unattended environment, it is almost impossible to replace the energy source. In order to save energy, the power consumption of the network should be reduced as much as possible. The LEACH protocol is one of the earliest proposed clustering routing algorithms for wireless sensor networks. It had a major impact on many subsequent routing protocols based on hierarchy. The protocol randomly elects cluster heads in the entire network periodically, and the member nodes send data to the cluster head nodes, and the cluster heads fuse the data and then send it to the sink node. After the cluster head node receives the joining request information sent by other nodes, it creates a time slot table, allocates a time sl...
