Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] A credible wireless sensor network data energy-saving convergence method of the present invention, such as figure 1 The sensor network model shown: (1), the sensor nodes are randomly and uniformly distributed in a rectangular area A; (2), there is a unique base station (BS) in a fixed position outside the area A; (3), all nodes have enough Computing power to support signal processing and calculation routing, and the status is equal; (4), the communication between nodes uses broadcast channels, and nodes can judge the distance of the source relative to itself according to the strength of the received signal, or the time of receiving data, etc. ; (5), the wireless transmission power is controllable, that is, the node can adjust the size of the transmission power according to the distance.

[0035] The aggregation method runs in rounds, and each r...

Abstract

The invention discloses a trusted energy-saving data convergence method for a wireless sensor network. The method comprises the following steps of: cluster head election, cluster migration and sensor node clearing-up, wherein all uncovered nodes are taken as cluster head nodes or become multi-hop member nodes of other clusters through neighbor nodes to finish node convergence. By the energy-saving data convergence method, the energy load of the whole network is equally allocated to each sensor node, and simultaneously, a data convergence technology is utilized to reduce energy consumption, eliminate data redundancy and increase available information streams from a source node to a base station, thereby fulfilling the aim of prolonging the service life of the whole network.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a method for evenly distributing the energy load of the entire network to each sensor node, while using data aggregation technology to reduce energy consumption, eliminate data redundancy, and increase the number of slave nodes The useful information flow to the base station, so as to achieve the purpose of prolonging the life of the overall network, is an energy-saving aggregation method, specifically, a reliable energy-saving aggregation method for wireless sensor network data. Background technique [0002] At present, Wireless Sensor Network (WSN) has broad application prospects in many fields, and is one of the hot spots in the current academic research. Due to the limited battery energy of the sensor node and the complex environmental conditions of the application, it is difficult for the node to replenish energy. Therefore, how to efficiently use the limited battery...
