Abstract
Clustering topology structure and weight constraint evolution model for WSNs are discussed and analyzed
and a node weight constraint release model is proposed.The proposed model optimizes the method establishing connections between nodes by mutual selection mechanism
limit nodes weight growth by setting node weight maximum threshold
and released the weight constraint effect on the nodes which reach the maximum threshold.And then
a new node is permitted to connect with the nearby node whose weight constraint is released
it is useful for reducing the energy loss of the node.Using MATLAB software simulation
compared the proposed model with the mutual selection model and the weight constraint model
the proposed model is more reasonable than the other two models in the distribution of the cluster head and the node weight.The proposed model reduces the energy consumption of WSNs effectively
