Abstract: 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, we 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. Data-aggregated Unequal Layered clustering protocol is used for inter-cluster communication. Simulation result shows that, our proposed algorithm effectively balances the energy consumption and increases the network lifetime.
