Optimal allocation of random access period for wireless body area network

引用

Journal of Central South University 2013年第8期20卷 2195-2201页

作者： jin hyuk KIM Chang ki HONG Sang bang CHOI Department of Electronic Engineering Inha University

A wireless body area network (WBAN) allows integration of low power, invasive or noninvasive miniaturized sensors around a human body. WBAN is expected to become a basic infrastructure element for human health monitoring. The Task Group 6 of IEEE 802.15 is formed to address specific needs of body area network. It defines a medium access control layer that supports various physical layers. In this work, we analyze the efficiency of simple slotted ALOHA scheme, and then propose a novel allocation scheme that controls the random access period and packet transmission probability to optimize channel efficiency. NS-2 simulations have been carried out to evaluate its performance. The simulation results demonstrate significant performance improvement in latency and throughput using the proposed MAC algorithm.

Controlled Probabilistic Teleportation of an Unknown Multi-Particle High-Dimensional Entangled State

引用

Communications in Theoretical Physics 2009年第6期51卷 1027-1032页

作者： SHI jin ZHAN You-bang Department of Physics Huaiyin Teachers College Huaian 223300 China

We propose a protocol for controlled probabilistic teleportation of an unknown tripartite qutrit entangled state with two partial tripartite qutrit entangled states as the quantum channel. It is found that teleportation associated with the generalized qutrit Bell-basis measurement, the generalized qutrit π-state measurement and the generalized Hadamard operator in three-dimensional Hilbert space. We generalize the protocol for controlled probabilistic teleportation of an unknown k-particle qudit entangled state with a multi-particle qudit entangled state and a tripartite qudit entangled state as the quantum channel. We also calculate the classical communication cost required in both cases.

Probabilistic Remote Preparation of a Tripartite High-Dimensional Equatorial Entangled State

引用

Communications in Theoretical Physics 2009年第2期51卷 239-243页

作者： SHI jin ZHAN You-bang Department of Physics Huaiyin Teachers College Huai＇an 223001 China

We present a scheme for probabilistic remote preparation of a tripartite qutrit entangled state with a partial tripartite qutrit entangled state and a partial bipartite qutrit entangled state as the quantum channel. It is found that a bipartite qutrit orthogonal projective measurement, an auxiliary qutrit particle, and the corresponding unitary transformation are required. A scheme for probabilistic remote preparation of a tripartite qudit equatorial entangled state by using a partial tripartite qudit entangled state and a partial bipartite qudit entangled state as the quantum channel is also proposed. We calculate the successful total probability and the total classical communication cost required in the RSP process, respectively.

A strange phenomenon in XZ Andromedae: two Keplerian periods with a 1:3 ratio

引用

Research in Astronomy and Astrophysics 2019年第9期19卷 63-70页

作者： jin-Zhao Yuan Sheng-bang Qian Department of Physics Shanxi Normal UniversityLinfen041004China Yunnan Observatories Chinese Academy of SciencesKunming650011China

Six mid-eclipse times of the eclipsing binary XZ And are obtained, which are analyzed together with others collected from the literature. Two sets of cyclic variations with periods of 33.43 and 100.4 yr are found if a double-Keplerian model is used to fit the data. The 1:3 ratio of the periods suggests that both cyclic variations arise from dynamic motions of two companions rather than magnetic activity of the eclipsing pair. According to the double-Keplerian model, the companions have masses of^1.32 M_⊙and^1.33 M_⊙, respectively. Comparing with the total mass of the eclipsing pair of 3.12 M_⊙, it is obvious that XZ And is a general N-body system. The strong gravitational perturbation between the two companions invalidates the double-Keplerian model. It is strange that two Keplerian periods with a 1:3 ratio are derived from the best fits with an 'inappropriate' model. This illogical, but interesting phenomenon also appears in two other Algol systems, suggesting that our discoveries deserve attention from astronomers.

Communications in Theoretical Physics 2018年第11期69卷 515-520页

作者： jin Shi You-bang Zhan School of Physics and Electronic Electrical Engineering Jiangsu Province Key Laboratory of Modern Measurement Technology and Intellige Huaiyin Normal University

The scheme for asymmetric and deterministic controlled bidirectional joint remote state preparation by using one ten-qubit entangled state as the quantum channel is proposed. In this scheme, Alice and David want to remotely prepare an arbitrary single-qubit state at Bob's site, at the same time, Bob and Eve wish to help Alice remotely prepare an arbitrary two-qubit entangled state. Alice and Bob can simultaneously prepare the desired states with the cooperation of David and Eve under the control of Charlie.
