1Enabling Energy Efficient Sensory Data Collection Using Multiple Mobile Sink显示文摘Mobile sink is the challenging task for wireless sensor networks(WSNs).In this paper we propose to design an efficient routing protocol for single mobile sink and multiple mobile sink for data gathering in WSN.In this process,a biased random walk method is used to determine the next position of the sink.Then,a rendezvous point selection with splitting tree technique is used to find the optimal data transmission path.If the sink moves within the range of the rendezvous point,it receives the gathered data and if moved out,it selects a relay node from its neighbours to relay packets from rendezvous point to the sink.Proposed algorithm reduces the signal overhead and improves the triangular routing problem.Here the sink acts as a vehicle and collect the data from the sensor.The results show that the proposed model effectively supports sink mobility with low overhead and delay when compared with Intelligent Agent-based Routing protocol(IAR) and also increases the reliability and delivery ratio when the number of sources increases.Madhumathy P Sivakumar D 2014China Communications2014,11,10:3
2焊接参数对搅拌摩擦焊接AA2219-T87材料韧性、洋葱圆环的断裂行为的影响(英文)显示文摘与熔焊相比,搅拌摩擦焊可以更好地保持材料的韧性和塑性,提高焊接的抗裂稳定性。本研究旨在提高焊接接头的延性和强度。刀具廓形在保持延性、分析金属流动行为和确定断裂起始点等方面起着重要作用。分析了洋葱圆环不同区域的微观结构,得出了洋葱圆环强度与金属流型的关系。结果表明,洋葱圆环强化了焊缝熔核。肩部和锥形螺纹型线刀具具有优异的力学性能。显微硬度数据表明,断口经过热影响区和热机械影响区等低硬度区。扫描电镜图像显示了细长的晶粒和韧窝,证实了断裂为韧性断裂。Dinesh KUMAR R S MUTHUKUMARAN Vincent XAVIER T VENKATESWARAN D SIVAKUMAR 2019Journal of Central South University2019,26,9:2
