A Novel Low-Complexity Low-Latency Power Efficient Collision Detection Algorithm for Wireless Sensor Networks

引用

Wireless Sensor Network 2015年第6期7卷 43-75页

作者： Fawaz Alassery Walid K. m. Ahmed mohsen Sarraf victor Lawrence Electrical and Computer Engineering Department Stevens Institute of Technology Hoboken NJ USA

Collision detection mechanisms in Wireless Sensor Networks (WSNs) have largely been revolving around direct demodulation and decoding of received packets and deciding on a collision based on some form of a frame error detection mechanism, such as a CRC check. The obvious drawback of full detection of a received packet is the need to expend a significant amount of energy and processing complexity in order to fully decode a packet, only to discover the packet is illegible due to a collision. In this paper, we propose a suite of novel, yet simple and power-efficient algorithms to detect a collision without the need for full-decoding of the received packet. Our novel algorithms aim at detecting collision through fast examination of the signal statistics of a short snippet of the received packet via a relatively small number of computations over a small number of received IQ samples. Hence, the proposed algorithms operate directly at the output of the receiver's analog-to-digital converter and eliminate the need to pass the signal through the entire. In addition, we present a complexity and power-saving comparison between our novel algorithms and conventional full-decoding (for select coding schemes) to demonstrate the significant power and complexity saving advantage of our algorithms.

Current vegetation dynamics of the “forest-mountain tundra” ecotones of Lake Baikal coastal ranges

引用

Natural Science 2013年第2期5卷 187-193页

作者： Alexander Sizykh victor Voronin Siberian Institute of Plant Physiology and Biochemistry Siberian Branch of Russian Academy of Sciences Irkutsk Russia

During last decades, new trends appeared in the ecotones of the upper boundary of forests at the ridges surroundingLakeBaikal(Khamar-Daban and Baikal’sky Ridge): ones to advance of wood species (Pinus sibirica Du Tour, Abies sibirica Ledeb., Larix sibirica Ledeb., Larix dahurica Lawson) out of timber stands into the area of subgoltsy with Pinus pumila (Pallas) Regel. up to mountain tundras. In average, this is from 100 to 200 - 300 meters (maximum up to500 m) in linear distance from the margin of dense timber stand. A burst of forests renewal occurred in 1989-1995, it resulted probably from a high productivity of the seeds of wood species due to warmer winters in 1980ies-1990ies which favoured the formation of favourable climate-edaphic conditions for the development of forest communities above the forests boundary on the ridges surrounding Lake Baikal.

To the space by laser light (II)

Natural Science 2012年第9期4卷 713-718页

作者： victor V. Apollonov A. m. Prokhorov General Physics Institute Vavilov str.38 Moscow Russia

New approach to the problem of laser jet engine (LJE) creation is based on the use of shock waves (SW) resonance association mechanism, generated by the optical pulsating discharge (OPD). For the creation OPD is proposed to use powerful pulse - periodic (P-P) laser radiation with duration of pulses ~ 100 - 150 ns and high pulse repetition frequency ~ 50 - 100 kHz. OPD is formed with the help of matrix of reflectors (mR). This is allowed: several times to increase the effectiveness of laser emission use for purposes of LJE creation, to avoid strong impact loads on the apparatus, to exclude the thermal action of laser plasma on the reflector, to decrease the laser emission screening by plasma, to remove the problem of the resonance oscillations appearance into the object moved with the help of laser. In our article the estimations of possible LJE thrust levels under the conditions of the proposed mechanism of reactive motion are given. Also, the new approaches to the creation of the high power high repetition rate laser systems for the “Impulsar” program are examined.

High power lasers and ecology of atmosphere (I)

作者： victor V. Apollonov A. m. Prokhorov General Physics Institute Vavilov str.38 Moscow Russia

There are many appearances in the literature of reliable observations of studying so-called “jets” and “sprites” - the discharges in the gigantic natural capacitor “Ionosphere-Earth” [1]. The volume of such a discharge is approximately 5-10 thousand cubic kilometers and usually it appears above the surface of ocean. There are the cases also of above mentioned discharges on the ground. The value of the energy transferred to the earth can comprise to several terajoule. Events are accompanied by the emission of the waves of ultra-low frequency. Their study has the significant interest from many points of view. The essence of the observed irregular phenomena consists of the electromechanical conversion of the energy excesses of natural electricity into mechanical and thermal energy of cyclones, typhoons and other natural cataclysms. The ionosphere can retain only the specific quantity of energy. Otherwise, it discards the surpluses of electricity through the atmosphere or transforms them into the energy of storms, in that number and inside the Earth. By using the part of the natural electricity for useful purposes it is possible to govern the weather of planet. Causing the artificial breakdowns of the ionosphere it could be possible to arrange the discharge of the controlled aqueous sediments at the necessary points of the globe. It could be possible as well to attempt to regulate the climate of planet and to decrease the amplitudes of the magnetic storms, earthquakes and hurricanes.

通过贝加尔裂谷系统北穆伊斯克(Severomuysk)段的密集地震台站线性网络获得的远距离强震记录,并利用P波接收函数技术,揭示了地壳和上地幔顶部的复杂分层块状结构。横波速度的分布表明构成北穆伊斯克地壳的地块具有不同性质。这些地块的西部聚散和地壳下部的分层证实了该地区隆起的堆积-碰撞起源。位于西伯利亚克拉通变薄的倾斜边缘上的北穆伊斯克段解释了该地区地壳碰撞效应的强度。2015年地震的震中深度与muyakan凹陷地壳上部的明显速度差异存在令人信服的相关性。
