Problems solved by technology

[0012] The technical problem that the present invention solves is: make good use of the node with bigger energy, allow to divide the area crosswise, instead of finding a superior node to act as the cluster head, and be responsible for all communication areas, reduce the burden of the cluster head like this, help To avoid excessive consumption of cluster heads in the hot zone, alleviate the problem of the hot zone, and effectively extend the life cycle of the network

Embodiment Construction

[0038] 1: The cluster head selection method is: when the network is initialized, the aggregation node collects and saves the ID information, location information, and remaining energy information of the nodes in the entire network, and then only updates the remaining energy of the nodes. The converging node sorts all nodes and energy, takes the top 5% points as the cluster head, and takes the radius r ch Search for nearby nodes to form a cluster. If the entire area cannot achieve full coverage, for the remaining unclustered nodes, take the node with the energy of the top 5% as the cluster head, and use the radius r ch Search for nearby nodes to form a cluster. This cycle is repeated until the entire area is fully covered by communication. After the node sleeps for a fixed time, it receives the network clustering table broadcast by the sink node.

[0039] Because the search radius r ch It is related to the remaining energy of the node and the distance from the sink k node. ...

Abstract

The invention relates to a clustering algorithm with balanced energy consumption in a wireless sensor network. The clustering algorithm is characterized in that the node with large energy is well usedfor taking charge of cluster head in the wireless sensor network, and the crossing region division is allowed, so that a clustering algorithm with balanced energy consumption is designed. The clustering algorithm disclosed by the invention has the advantage an advantage node is unfound to be responsible for taking nodes in all communication regions, the cluster head burden is reduced, the excessive consumption of the cluster head in a hotspot is avoided, and a hotspot problem is relieved. Compared with the DCEM algorithm, the clustering algorithm has the advantage on the network total energyconsumption and the survival node number, and the network life cycle can be well prolonged.

Description

technical field [0001] The invention relates to a clustering algorithm for energy balance in a wireless sensor network, which can be used for node clustering in a wireless sensor network for energy balance, so as to achieve the goal of prolonging the network life cycle. Background technique [0002] The wireless sensor network is composed of a large number of cheap micro-sensor nodes deployed in the monitoring area, and forms a self-organizing network system through wireless communication. sent to observers. According to different topological structures, the routing protocols of wireless sensor networks can be divided into flat routing protocols and cluster routing protocols. Due to the poor scalability of the flat routing protocol and the small network scale, the application is limited. The clustering routing protocol is widely used because of its excellent performance in scalability, fault tolerance and energy saving. [0003] In the wireless sensor network, the cluster...
