碩士 === 朝陽科技大學 === 網路與通訊研究所 === 96 === In cluster-based wireless sensor networks (WSNs), the most of energy is consumed in cluster head (CH) which performs data aggregations and relaying. The lifetime in cluster-based WSN is subjected by the lifetime of CHs. Therefore, in this paper, we equalize the energy consumption of the CHs to prolong the lifetime of WSNs. After equalization, we obtain the length of sides of cluster area. Numerical results show that the length of far site cluster is shorter than the nearest cluster to perform equalization for all three routing schemes. Moreover, the circular area of WSNs is also adopted to perform energy equalization for CHs in this thesis. Furthermore, simulation results verify that the proposed energy equalization for CHs is effective for both rectangular and circular WSNs and no matter direct transmission, two-hop or three-hop transmission.
