A double cluster head based wireless sensor network routing algorithm

A double cluster head based wireless sensor network routing algorithm is proposed aiming at the premature death of the cluster head due to very fast energy consumption and the unbalanced energy consumption of nodes. Firstly, the master cluster heads and the member nodes of the cluster are determined based on the LEACH algorithm. Secondly, the vice cluster head is selected from cluster member nodes according to energy consumed by all the member nodes to complete a process of data transmission, collection and fusion based on the principle of minimum energy consumption. Any member node in the cluster transmits the data to the cluster head near to it. Both the master cluster head and the vice cluster head collect and integrate the data, which effectively reduces and balances the energy consumption of nodes. Based on the simulation results, compared with the LEACH algorithm, the algorithm proposed in this article significantly delays the death time of the first node in the wireless sensor network, increasing the life cycle of the network by about 75%.
