2011 IEEE 3rd International Conference on Communication Software and Networks(ICCSN 2011)

作者： Huiyong Yuan Department of Computer Science hunan institute of humanities,Science and Technology Loudi hunan,China Jiansheng Xie Network Center Loudi Vocational&Technical College Loudi hunan,China

In multi-hop wireless sensor networks,the nodes closest to the sink tend to deplete their energy faster than other nodes,which is known as energy-hole *** address this problem,we first study the mobile sink model,and conclude the best mobility *** then consider jointly sink mobility and node deployment,and formulate optimization problems that maximize the network lifetime subject to energy depletion ***,we propose a non-uniform node deployment strategy for periodical data gathering in sensor *** experiments show that the proposed deployment strategy outperforms random deployment better scalability and longer network lifetime.

2011 IEEE International Conference on Computer Science and Automation Engineering(CSAE 2011)

作者： Huiyong Yuan,Yongyi Liu Department of Computer Science hunan institute of humanities,Science and Technology Loudi hunan,China Jianping Yu College of Mathematics & Computer Science hunan Normal University Changsha,China

＜正＞Clustering provides an effective way for extending the lifetime of a sensor *** cluster heads cooperate with each other to forward their data to the base station,the cluster heads closer to the base station are burdened with heavy relay traffic and tend to die early, leaving areas of the network uncovered and causing network *** address the problem,we propose an energy-efficient Unequal Clustering Algorithm（UCA） for data gathering,which can lead to more uniform energy dissipation among the cluster head nodes,thus increasing network *** results show that UCA outperforms M-LEACH significantly with prolonging the network lifetime over 22%.

Because of the enhancement of micro UAV's ability of autonomous decision as well as the continuous improvement of network data link, cooperation between multiple UAVs is made possible, In order to research the Multi-UAVs' cooperative system , This article, starting with the tactical level, tries to establish a general framework about conscious cooperation of a group of UAVs, So the paper studies the status of Multi-UAVs cooperative system under the information network, and establishes a mathematical model of cooperative system using Stochastic Process and Probability Analysis, and proposes the uniqueness and Controllability theorem for system solutions existence. The example results show that the method is reasonable.
