Organizing wireless sensor networks into clusters ensures the effective utilization of limited energy resources of the sensor nodes. The problem of unbalanced energy consumption and hot-spots problem remain unavoidable. To solve this problem, the authors propose an Enhanced Energy Efficient Unequal Layered Clustering Algorithm (EEEULCA), which leads to the uniform energy dissipation among the cluster heads. Layer close to the base station will have smaller size than from the outer, which can preserve more energy for data forwarding.
