Embodiment Construction

[0012] It is easy to understand that, according to the technical solution of the present invention, those skilled in the art can imagine various implementations of the wireless sensor network data transmission method of the present invention without changing the essence of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or limitation on the technical solution of the present invention.

[0013] The present invention first selects the cluster head according to factors such as the remaining energy of each node of the wireless sensor, the distance from each node to the base station, and the distance from each node to the cluster head, and the nodes that have not become the cluster head choose to join the cluster where the cluster head closest to it is located. In order to divide t...

Abstract

The invention provides an inhomogeneous clustering multihop wireless sensor network routing protocol based on energy balance. A wireless sensor network data transmission method comprises the followingsteps: voting a cluster head according to residual energy of the nodes, the distances from the nodes to a base station and the distances from the nodes to the cluster head, separately adding the nodes not becoming the cluster head to the cluster where the cluster head having the shortest distances with the nodes is located; then, constructing, by the cluster head, an optimal transmission path based on a minimum spanning tree according to the residual energy and the distance to the base station so as to find the optima next hop forwarding cluster head; and finally transmitting data to the basestation by the nodes in a single hop in the cluster and a multihop communication mode between the clusters. By adoption of the method, the energy of the nodes can be effectively saved, the energy consumption of the nodes can be balanced, and thus the life cycle of the wireless sensor network is prolonged.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and relates to a wireless sensor network data transmission method, in particular to a wireless sensor network routing protocol based on energy balance non-uniform clustering and multi-hop. Background technique [0002] Wireless Sensor Networks (WSN) is a cross product of emerging disciplines and traditional disciplines, which includes high-tech in various fields such as micro-sensors, wireless communication, low-power embedded, and biology. It is an ad hoc network composed of a large number of sensor nodes. These nodes have limited energy, computing power, and storage capacity, and because they are often deployed in areas that are difficult for people to reach, their energy is not easy to be supplemented or replaced. Through wireless communication, the nodes in the network can transmit the collected data information to the base station in a single-hop or multi-hop manner. The wi...
