Ad hoc 네트워크에서의 power-aware 라우팅 개발
河??蘭 弘益大學校 科學技術硏究所 2005 科學技術硏究論文集 Vol.16 No.-
In ad hoc networks, nodes' limited energy capacity affects the entire network's lifetime and reliability. So a large number of power-aware routing protocols have been proposed to overcome these energy consumption problems. So far, existing power-aware routing protocols basically consider nodes' residual energy capacity and transmission power. This paper refers to the proposed power-aware routing protocol as TPR(Traffic load based Power-aware Routing protocol) and it does not only consider nodes' residual energy capacity and transmission power, but also intermediate nodes' traffic load in route discovery process. It helps to extend the entire network's lifetime and to achieve load-balancing of nodes. Simulation results using ns-2[11] simulator show that the proposed routing protocol outperforms other routing protocols in terms of the number of dead nodes.

Effective learning demands awareness and spontaneous execution of an optimal study schedule. While prior research suggests the opposite, learners tend to believe that learning from a blocked schedule (grouping exemplars by category) is more effective than learning from an interleaved schedule (intermixing exemplars). We investigated how the initial learning experience affected learners’ selection of a subsequent study schedule using a painting-style learning task. Participants studied the first section in an interleaved schedule and were given a different interim activity on that section (test vs. restudy). They were then asked to select their own study schedule for the second section between interleaved and blocked schedules. After that, participants took a final transfer test and again selected a subsequent study schedule. Participants were also asked to make judgments of learning (JOL) several times (after study and after test) throughout the experiment. The results revealed that the interleaving-selectors showed better learning on the subsequent section, demonstrating a robust interleaving effect. More interestingly, the first selection of interleaving schedule was predicted by learners’ better interim-test performance. Furthermore, participants who experienced improvement via testing or via JOL throughout the experiment were more likely to stay on the same study schedule. These findings suggest that providing learners with a successful learning experience may be one way of encouraging them to choose and continue a more effective interleaving study method.
