Problems solved by technology

[0005] The present invention provides a wireless sensor network multi-principal component analysis data compression method, which can effectively solve the single principal component analysis data compression method, which can only eliminate the correlation between data collected by different nodes in the same cluster for a period of time, while It is impossible to eliminate the correlation problem between adjacent cluster head data on the same layer routing, and at the same time improve the total data compression ratio, reduce communication overhead and energy consumption of sensor nodes, and prolong the network life cycle

Embodiment Construction

[0044] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0045] figure 1It is a schematic diagram of a three-layer cluster hierarchical routing tree model of the wireless sensor network cluster hierarchical routing protocol of the present invention. In order to facilitate the modeling of the wireless sensor network cluster hierarchical routing protocol, the following reasonable assumptions are made:

[0046] 1) Each node of the wireless sensor network is evenly distributed on a two-dimensional plane, and each node has obtained its own geographical location information and remains static;

[0047] 2) All sensor nodes have the same communication radius, and the average energy consumption for transmitting any unit of bit data is the same;

[0048] 3) The position of the sink node is fixed, and the cluster heads of each layer transmit the processed data to the sink node step by step;

[0049] 4) The softw...

Abstract

The invention relates to a method for compressing multiple principle component analysis data of a wireless sensor network. Data compression is performed by iteratively using principle component analysis on a plurality of layers of routers in the wireless sensor network, so that the relativity between data acquired by different nodes in the same cluster within a certain period of time and the relativity between primarily extracted principle components of adjacent clusters on the same layer of the routers are effectively eliminated and data compression ratio can be further enhanced on the premise of ensuring data reconstruction accuracy required by a user. Therefore, the method can reduce energy consumption of a sensor node and prolong network lifetime and can be used in cluster layered routing protocol algorithm of the wireless sensor network.
