TL;DR: Analytical proofs and simulation results show that energy-efficient information reliability can be guaranteed in an unreliable wireless environment with the help of the proposed schemes.
Abstract: Energy-efficient and reliable transmission of sensory information is a key problem in wireless sensor networks. To save more energy, in-network processing such as data fusion is a widely used technique, which, however, may often lead to unbalanced information among nodes in the data fusion tree. Traditional schemes aim at providing reliable transmission to individual data packets from source node to the sink, but seldom offer the desired reliability to a data fusion tree. In this paper, we explore the problem of Minimum Energy Reliable Information Gathering (MERIG) when performing data fusion. By adaptively using redundant transmission on fusion routes without acknowledgments, packets with more information are delivered with higher reliability. For different data fusion topologies, such as star, chain, and tree, we provide optimal solutions to compute the number of transmissions for each node. We also propose practical, distributed approximation algorithms for chain and tree topologies. Analytical proofs and simulation results show that energy-efficient information reliability can be guaranteed in an unreliable wireless environment with the help of our proposed schemes.

TL;DR: In this paper, two fundamental invertible transformations, namely serial nonlinear transformation and parallel non-linear transformation, are proposed to carry out the decorrelation for neutral vector variable.
Abstract: In this paper, we propose novel strategies for neutral vector variable decorrelation. Two fundamental invertible transformations, namely, serial nonlinear transformation and parallel nonlinear transformation, are proposed to carry out the decorrelation. For a neutral vector variable, which is not multivariate-Gaussian distributed, the conventional principal component analysis cannot yield mutually independent scalar variables. With the two proposed transformations, a highly negatively correlated neutral vector can be transformed to a set of mutually independent scalar variables with the same degrees of freedom. We also evaluate the decorrelation performances for the vectors generated from a single Dirichlet distribution and a mixture of Dirichlet distributions. The mutual independence is verified with the distance correlation measurement. The advantages of the proposed decorrelation strategies are intensively studied and demonstrated with synthesized data and practical application evaluations.

TL;DR: In this paper, the authors analyze basic concepts and features of Internet of Things, and compare the relationships among Internet of things, the ubiquitous network, machine to machine, and the cyber physics system.
Abstract: Internet of things is closely related to numerous fields.We first analyze basic concepts and features of Internet of things,and compare the relationships among Internet of things,the ubiquitous network,machine to machine,and the cyber physics system.Then,we introduce the ubiquitous sensor network(USN) architecture designed by the International Telecommunication Union,and present research proposals for Internet of things architecture.Furthermore,we summarize the key technologies of Internet of things and propose the model of Internet of things technology system.Finally,the status of standardization is concluded and several development proposals are suggested for Internet of things.
