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, including 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 overlap ...

Abstract

The invention discloses a cluster head selection method for a wireless sensor network for area coverage monitoring, which comprises the following steps: selecting a node conforming to a cluster head selection condition from candidate nodes as a cluster head, wherein the candidate nodes are the nodes that normally work in the same cluster, the remaining candidate nodes are used as member composition nodes; the member composition nodes are used for collecting sensing data and sending the sensing data to the cluster head; and the cluster head is used for sending the sensing data to a base station. The cluster head selection method for the wireless sensor network for area coverage monitoring in the present invention considers the choice of cluster heads, and requires that the selected clusterhead can minimize the area of uncovered areas, thereby facilitating the energy consumption of the cluster head node, and making full use of the feature that the sensing range of the member node can completely overlap with the cluster head sensing range. In the case of not spending too much energy, the related work is efficiently performed, thereby increasing the network lifetime of the wireless sensor network.

Description

technical field [0001] The invention relates to the technical field of communication, 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, imbalances...
