Problems solved by technology

[0004] In the cluster establishment process of the LEACH protocol, the location distribution of the cluster heads is not considered, and the cluster heads selected by the protocol will lead to the uneven size of the formed cluster structure
In the area where the cluster head is scattered, some clusters have too many member nodes in the cluster, and the cluster head will consume a lot of energy in collecting and processing information; at the same time, some member nodes are far away from the cluster head. More energy is consumed when transmitting information

Embodiment Construction

[0083] see figure 1 , assuming each node knows its geographic location. According to the number of selected cluster heads and layers, the nodes are divided into several cuboids, and the nodes in the corresponding cuboids in different cycles participate in the cluster head according to their own positions and remaining energy. The cluster head node chooses to join the corresponding cluster structure according to the distance to each cluster head. The cluster head establishes the backbone route, and each cluster head chooses the cluster head node that is one layer higher than itself and the closest to itself as the next hop node. In the stable data transmission stage, the member nodes send the collected data to the cluster head, and the cluster head compresses the received information and sends it to the next hop node or base station. After a period of time (preset), the network monitoring enters the next cycle.

Abstract

The invention relates to a layer-based clustering routing protocol method applied to a three-dimensional underwater acoustic sensor network. Under the conditions of a known monitoring range and a node maximum transmission distance, optimal layer number guaranteeing the network connection and optimal cluster head number under the condition that the layer number is given are determined; in the stage of selection of the cluster head, the position of a node participating in cluster head selection is limited, and the node participating in the selection decides whether to be a cluster head according to a competitive factor; in the stage of formation of an inter-cluster routing, the cluster head selects a cluster head node which is one layer higher and is closest to self as a relay node; in a stable data transmission stage, member nodes transmit the information to corresponding cluster heads, the cluster heads compress the received information and then send the compressed information to the relay node or a base station. The method can effectively balance the energy consumption of the network nodes and save the total energy consumed in the network.

Description

technical field [0001] The invention relates to a routing protocol of a sensor network layer, in particular to a layered-based clustering routing protocol method applied to a three-dimensional underwater acoustic sensor network, and belongs to the technical field of underwater acoustic signal processing. Background technique [0002] In underwater acoustic communication networks, sensor nodes are generally powered by batteries with limited energy. Since it is unrealistic to replenish energy for nodes by charging or replacing batteries, it is necessary to save network energy when designing routing protocols for underwater acoustic communication networks. Energy consumption is the first consideration. The clustering routing protocol can perform data fusion on the data monitored by multiple nodes, which reduces the amount of data transmitted in the network, thereby reducing energy consumption. Therefore, clustering routing protocols have attracted much attention in underwater ...
