Abstract: To solve the problem of energy consumption in wireless sensor network with randomly distributed nodes, a low energy consumption routing algorithm which is obtained by adopting equilateral triangle model to rationally manage redundant work nodes after effective clustering is proposed. This algorithm firstly calculates clustering number within network when the total nodes energy consumption is minimum, then sink nodes select corresponding nodes which have the largest residual energy and optimal geographic position as cluster head to complete uniformly clustering. Subsequently, clustering nodes adopt equilateral triangle model and node coverage ratio to select working nodes. Simulation show that the improved routing algorithm can balance node energy consumption, to extend network working round number, reduce network delay, and reflect optimal network robustness.
