Geographic gossip: Efficient averaging for sensor networks
收藏 引用
IEEE TRANSACTIONS ON signal processing 2008年 第3期56卷 1205-1216页
作者: Dimakis, Alexandros D. G. Sarwate, Anand D. Wainwright, Martin J. Univ Calif Berkeley Dept Elect Engn & Comp Sci Berkeley CA 94720 USA Univ Calif Berkeley Dept Stat Berkeley CA 94720 USA
Gossip algorithms for distributed computation are attractive due to their simplicity, distributed nature, and robustness in noisy and uncertain environments. However, using standard gossip algorithms can lead to a sig... 详细信息

distributed beamforming for relay networks based on second-order statistics of the channel state information
收藏 引用
IEEE TRANSACTIONS ON signal processing 2008年 第9期56卷 4306-4316页
作者: Havary-Nassab, Veria Shahbazpanahi, Shahram Grami, Ali Luo, Zhi-Quan Univ Ontario Inst Technol Fac Engn & Appl Sci Oshawa ON L1H 7K4 Canada Univ Minnesota Dept Elect & Comp Engn Minneapolis MN 55455 USA
In this paper, the problem of distributed beam-forming is considered for a wireless network which consists of a transmitter, a receiver, and r relay nodes. For such a network, assuming that the second-order statistics... 详细信息

IEEE signal processing LETTERS 2008年 第1期15卷 473-476页
作者: Zhang, Li Zhang, Xian-Da Gao, Qiubin Tsinghua Univ Dept Automat Natl Lab Informat Sci & Technol Beijing 100084 Peoples R China
This letter analyzes the performance of several typical one-bit universal distributed estimation schemes (DESs) in bandwidth-constrained sensor networks. We theoretically obtain the mean and mean-square error (MSE) of... 详细信息

作者: Fazeli-Dehkordy, Siavash Gazor, Saeed Shahbazpanahi, Shahram Queens Univ Dept Elect & Comp Eng Walter Light Hall Kingston ON K7L 3N6 Canada Univ Ontario Inst Technol Fac Engn & Appl Sci London ON LIH 7K4 Canada
We consider an ad hoc network consisting of d source-destination pairs and R relaying nodes. Each source wishes to transmit its data to its corresponding destination through the relay network. Each relay in the networ... 详细信息

33rd IEEE International Conference on Acoustics, Speech and signal processing
作者: Oreshkin, Boris N. Aysal, Tuncer C. Coates, Mark J. McGill Univ Dept Elect & Comp Engn Montreal PQ H3A 2T5 Canada
The average consensus problem in the distributed signal processing context is addressed by linear iterative algorithms, with asymptotic convergence to the consensus. The convergence of the average consensus for an arb... 详细信息

IEEE Wireless Communications and Networking Conference
作者: Zhang, Li Zhang, Xian-Da Gao, Qiubin Han, Fang-Ming Tsinghua Univ Dept Automat Tsinghua Natl Lab Informat Sci & Technol Beijing 100084 Peoples R China
This paper presents a distributed estimation scheme (DES) along with the bit allocation algorithm, which minimizes the total required bandwidth while ensuing a given average estimation mean-squared error (MSE). The DE... 详细信息

IEEE TRANSACTIONS ON signal processing 2007年 第5期55卷 1634-1643页
作者: Li, Junlin AlRegib, Ghassan Georgia Inst Technol Sch Elect & Comp Engn Atlanta GA 30332 USA
In this paper, we consider the distributed parameter estimation in wireless sensor networks where a total bit rate constraint is imposed. We study the optimal tradeoff between the number of active sensors and the quan... 详细信息
