| Summary: | 碩士 === 國立屏東教育大學 === 資訊科學系 === 98 === In recent years due to the improving of microfabrication and semiconductor technology, the designed sensor nodes have more processing power but with smaller size. It impetus more practical applications have been developed in wireless sensor networks. Since the battery power of a sensor node is limited, thus it ultimately could not avoid the problem of node power depletion. Therefore, how to design a scheme to manage the consumption of battery power of sensor nodes to extend the network lifetime is a very important issue. In this thesis, a Honey-bee optimization algorithm is proposed to determine a proper mobile sink’s moving scheduling. The considered sink node is capable of moving, while the remaining nodes are stationary. The experimental results shows that the proposed Honey-bee mating optimization algorithm can effectively arrange the mobile sink’s moving scheduler to balance the power consumption of each node and to prolong the network lifetime of a sensor network.
