      Distributed consensus and linear functional calculation in networks: An observability perspective 

      Sundaram, S.; Hadjicostis, Christoforos N. (2007)
      We study the problem of performing sensor fusion and distributed consensus in networks, where the objective is to calculate some linear function of the initial sensor values at some or all of the sensors. We utilize a ...

      Efficient online state tracking using sensor networks 

      Halkidi, Maria; Kalogeraki, Vana; Gunopulos, Dimitrios; Papadopoulos, Dimitris; Zeinalipour-Yazdi, Constantinos D.; Vlachos, Michail (2006)
      Sensor networks are being deployed for tracking events of interest in many environmental or monitoring applications. Because of their distributed nature of operation, a challenging issue is how to accurately identify the ...

      Hierarchical decentralized fusion from correlated sensor measurements 

      Takos, G.; Hadjicostis, Christoforos N. (2005)
      In this paper we consider hierarchical decentralized fusion of possibly correlated noisy measurements of a random variable. Our goal is to obtain initial estimates in a decentralized fashion (based on disjoint groupings ...

      Towards in-situ data storage in sensor databases 

      Zeinalipour-Yazdi, Constantinos D.; Kalogeraki, Vana; Gunopulos, Dimitrios; Mitra, Abhishek; Banerjee, A.; Najjar, W. (2005)
      The advances in wireless communications along with the exponential growth of transistors per integrated circuit lead to a rapid evolution of Wireless Sensor Devices (WSDs), that can be used for monitoring environmental ...
