Clustering data fusion algorithm based on relay node mechanism

Wireless Sensor Network based on clustering of cluster head selection mechanism is not reasonable,and the uneven energy consumption be cause of the networks' short life cycle.So we put forward the Clustering Data Fusion algorithm based on Relay Node Mechanism.Cluster head are selected based on the trust value and energy trust data in different points within the cluster algorithm,and in each individual cluster choose a relay node.Cluster head to collect data and integration of cluster members,then sent it to the relay node.Data communication and other work with the base station not cluster head nodes but relay node,in each round of cluster head energy consumption will be significantly reduced.Compared to traditional LEACH algorithm simulation experiment, the result shows that this algorithm is effective to extend the life cycle of wireless sensor network by 16%,and balancing the energy consumption in a certain procedure.
