Abstract: Using energy-efficient routing protocol, wireless sensor networks can save much energy, but there are still the problems of rapid and uneven energy consumption. LEACH, called low energy adaptive clustering hierarchy routing protocol, is one of the most classical routing protocols, which ignores both the rate of energy dissipation and the distance between normal node and sink node during the election of cluster header. Focusing on these limitations, a novel clustering routing protocol was proposed. Experimental results show that the new protocol makes the consumption of energy more balanced, decreases energy dissipation and extends the lifetime of sensor network.
