Regarding energy consumption for different degrees of nodes in a wireless sensor network

it proposed the energy cluster head selection mechanism

based on the cost of energy. In this mechanism

the first common node was seen as the cluster head node. Nodes

necessary node energy consumption

and the current energy surplus value were computed. With the proposed concepts and formulas

the above energy-related value was converted into the value of energy loss speed of the selected clusters at measur-able sensor nodes. Simulation results show that the algorithm has a better cluster head selection

and it can effectively extend the network life cycle.
