Abstract

The invention relates to a wireless sensing routing algorithm with cluster cellular segmentation(CC-HEED) based on energy balance and aims to solve a problem that events are frequent in a part of area in a wireless sensing network, an energy consumption hot area is formed, network load imbalance is caused, and the lifetime of the network is shortened. For a problem that wireless sensing network energy is limited, on the basis of analyzing and studying an HEED routing algorithm, through establishing the energy loss model of a wireless sensing node, the cellular segmentation again of a cellular area which is subjected to hierarchical clustering is carried out, and combined with the annular layering of cluster head nodes, the balanced distribution of the network energy in time and space is realized. Compared with the existing wireless sensing routing algorithm, according to the method, the energy consumption of the network can be effectively reduced, a balance between the complexity and energy consumption of the network is achieved, and a long network life cycle and good energy load balance are obtained.

Description

Technical field: [0001] The invention relates to a wireless sensor routing algorithm based on energy balance cell division in a cluster. Background technique: [0002] A wireless sensor network is a distributed network composed of a large number of low-power, low-processing, and short-distance transmission intelligent sensor nodes through self-organizing communication. corresponding data information. A large number of sensing nodes are randomly distributed in the sensing area of ​​interest, and the physical information around the nodes is collected, processed, and wirelessly transmitted, and the collected data is aggregated, analyzed, and stored by the base station.
