Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The invention discloses a wireless sensor network cluster head selection method for area coverage monitoring, which includes the following steps:

[0025] Select a node that meets the selection conditions of the cluster head from the candidate nodes as the cluster head, the candidate node is a node that works normally in the same cluster, and the remaining candidate nodes are used as member nodes, and the member node is used to collect and sense data and send the sensing data to the cluster head, and the cluster head is used to send the sensing data to the base station;

[0026] The way to judge whether the candidate node satisfies the selection condition of the cluster head is as follows:

[0027] calculate Among them, MN1 to MNn represent all candidate nodes in a cluster, Indicates the perception coverage area of ​​the jth candidate node, S ove...

Abstract

The invention discloses a cluster head selection method of a wireless sensor network for area coverage monitoring, includes the following steps: a node that meets the cluster head selection criteria is selected from the candidate nodes as the cluster head, the candidate node is a node working normally in the same cluster, and the remaining candidate nodes are used as member nodes, the member nodesare used for collecting perceptual data and sending the perceptual data to a cluster head, and the cluster head is used for sending the perceptual data to a base station. The present invention takesinto account the selection of cluster heads and requires that the selected cluster heads minimize the area of an uncovered area. This is conducive to the energy consumption of the cluster head node, and makes full use of the characteristics that the sensing range of the member node can completely overlap with the sensing range of the cluster head. Without too much energy consumption, the related work is completed efficiently, which increases the network lifetime of wireless sensor networks.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for selecting a cluster head of a wireless sensor network for area coverage monitoring. Background technique [0002] Wireless sensor networks have become an increasingly important research field. It has been realized to be useful in various applications such as reconnaissance in war zones, natural disaster alerts, mass sampling and smart homes. A typical wireless sensor network usually includes a large number of cheap wireless sensor nodes, which have the functions of sensing, processing and forwarding data. These nodes are usually placed in areas that are not directly accessible. Different wireless sensor network protocols are used to improve network performance and cooperate through self-organizing features. These factors help to form an ad-hoc (peer-to-peer) network of randomly scattered sensor nodes. Since each node is small and battery-powered, imbalance...
