Embodiment Construction
[0011] The purpose of the present invention is to reduce the energy consumption problem caused by network reconstruction and provide an expandable wireless sensor network clustering method. First of all, in the election process of candidate cluster heads, the remaining energy of nodes in the network is considered, which reduces the probability of low-energy nodes becoming candidate cluster heads; secondly, in the process of election of cluster heads, considering the remaining energy of candidate nodes, Factors such as the number of neighbor nodes of the candidate cluster heads, the value of each node to the candidate cluster heads, etc., not only ensure that the selected cluster heads have high energy, but also ensure that the cluster heads are distributed in areas where nodes are relatively concentrated. The transmission distance of data is reduced to reduce energy consumption, which is beneficial to prolong the life cycle of the network. In addition, when the average energy ...
