Abstract

The invention relates to a non-uniform clustering and multi-hop energy consumption balance wireless measurement method and a non-uniform clustering and multi-hop energy consumption balance wireless measurement device. By adopting a method combining non-uniform clustering and multi-hop routing, the quantity of clustered nodes which are relatively close to a base station is relatively few, so that a cluster head consumes relatively less energy in in-cluster communication and relatively much energy can be used for transmitting transmission data of a far-distance cluster head to the base station. In wireless measurement of the concentration of dissolved oxygen in aquaculture, by optimizing uniform clustering in a LEACH wireless communication protocol, multi-hop communication is used for transmitting the data to the base station from the far-distance cluster head according to the length of a wireless communication transmission distance, so that the energy consumption of each communication node is relatively balanced and the effect of prolonging the effective life cycle of a wireless communication network is realized.

Description

technical field [0001] The invention relates to the field of measurement of dissolved oxygen concentration in aquaculture, in particular to a non-uniform clustering multi-hop energy balance wireless measurement method and a device thereof. Background technique [0002] In order to prolong the effective life cycle of the wireless sensor network, a low energy adaptive clustering hierarchy (LEACH) is generally adopted. In the LEACH protocol, all nodes act as the cluster head in turn, and the cluster head fuses the measurement data of other nodes in the cluster and sends it to the base station in a single-hop manner. When the measurement range is relatively short (the communication distance between the cluster head and the base station is less than e fs For free space transmission parameters, e mp is the multipath attenuation transmission parameter, d 0 Indicates the wireless communication distance), using the Friss Free Space Model (FrissFreeSpaceModel), the propagation en...
