  • Zhu, Minghui; Martínez, Sonia (Society for Industrial and Applied Mathematics, 2013-01)
    Inspired by current challenges in data-intensive and energy-limited sensor networks, we formulate a coverage optimization problem for mobile sensors as a (constrained) repeated multiplayer game. Each sensor tries to optimize ...
  • Eryilmaz, Atilla; Ozdaglar, Asuman E.; Shah, Devavrat; Modiano, Eytan H. (Institute of Electrical and Electronics Engineers, 2010-04)
    In this paper, we provide and study a general framework that facilitates the development of distributed mechanisms to achieve full utilization of multihop wireless networks. In particular, we describe a generic randomized ...
  • Agaskar, Ameya P.; He, Ting; Tong, Lang (Institute of Electrical and Electronics Engineers, 2010-05)
    The problem of detecting multihop information flows subject to communication constraints is considered. In a distributed detection scheme, eavesdroppers are deployed near nodes in a network, each able to measure the ...
  • Gattami, Ather Said (Institute of Electrical and Electronics Engineers, 2009-06)
    In this paper we study distributed estimation and control problems over graphs under partially nested information patterns. We show a duality result that is very similar to the classical duality result between state ...
  • Dimarogonas, Dimos V.; Frazzoli, Emilio (Institute of Electrical and Electronics Engineers, 2010-01)
    Event-driven strategies for distributed multi-agent systems are motivated by the future use of embedded microprocessors with limited resources that will gather information and actuate the individual agent controller updates. ...
  • Le Ny, Jerome; Balakrishnan, Hamsa (Institute of Electrical and Electronics Engineers, 2009-06)
    This paper proposes an Eulerian model of traffic flows in the National Airspace System (NAS) and presents a distributed feedback control approach for managing the flows. The main contribution is the development of a model ...
  • Kassakian, J.G.; Perreault, David J.; Kassakian, John G. (Institute of Electrical and Electronics Engineers (IEEE), 1997-08)
    This paper introduces a distributed approach to interleaving paralleled power converter cells. Unlike conventional methods, the distributed approach requires no centralized control, automatically accommodates varying numbers ...
  • Sorin, Fabien; Lestoquoy, Guillaume; Danto, Sylvain; Joannopoulos, John D.; Fink, Yoel (Optical Society of America, 2010-05)
    We report on a photoconductive fiber that supports decaying and convex electrical potential profiles capable of localizing a point of illumination, and propose a scheme to perform distributed optical sensing.
  • Roozbehani, Mardavij; Megretski, Alexandre; Frazzoli, Emilio; Feron, Eric (Spring Berlin/Heidelberg, 2008-07)
    In previous works, the authors introduced a framework for software analysis, which is based on optimization of Lyapunov invariants. These invariants prove critical software properties such as absence of overflow and ...
  • Lobel, Ilan; Ozdaglar, Asuman E.; Feijer Rovira, Diego Francisco (Springer-Verlag, 2011-06)
    We study distributed algorithms for solving global optimization problems in which the objective function is the sum of local objective functions of agents and the constraint set is given by the intersection of local ...
  • Jadbabaie, Ali; Ozdaglar, Asuman E.; Zargham, Michael (Institute of Electrical and Electronics Engineers, 2009-12)
    Most existing work uses dual decomposition and subgradient methods to solve network optimization problems in a distributed manner, which suffer from slow convergence rate properties. This paper proposes an alternative ...
  • Wei, Ermin; Ozdaglar, Asuman E.; Jadbabaie, Ali (Institute of Electrical and Electronics Engineers, 2010-12)
    Most existing work uses dual decomposition and subgradient methods to solve Network Utility Maximization (NUM) problems in a distributed manner, which suffer from slow rate of convergence properties. This work develops an ...
  • Jiang, Libin; Shah, Devavrat; Shin, Jinwoo; Walrand, Jean (Institute of Electrical and Electronics Engineers, 2010-11)
    This paper provides proofs of the rate stability, Harris recurrence, and ε-optimality of carrier sense multiple access (CSMA) algorithms where the random access (or backoff) parameter of each node is adjusted dynamically. ...
  • Boerkoel, James; Durfee, Edmund H. (Association for the Advancement of Artificial Intelligence, 2013-05)
    This research focuses on building foundational algorithms for scheduling agents that assist people in managing their activities in environments where tempo and complex activity interdependencies outstrip people's cognitive ...
  • Misra, Vinith; Goyal, Vivek K.; Varshney, Lav Raj (Institute of Electrical and Electronics Engineers (IEEE), 2011-07)
    Communication of quantized information is frequently followed by a computation. We consider situations of distributed functional scalar quantization: distributed scalar quantization of (possibly correlated) sources followed ...
  • Dimarogonas, Dimos V.; Frazzoli, Emilio; Johansson, Karl H. (Institute of Electrical and Electronic Engineers, 2010-12)
    It is desirable to limit the amount of communication and computation generated by each agent in a large multi-agent system. Event- and self-triggered control strategies have been recently proposed as alternatives to ...
  • Modiano, Eytan H.; Le, Long Bao; Lee, Hyang-Won (Institute of Electrical and Electronics Engineers, 2009-10)
    We consider throughput-optimal power allocation in multi-hop wireless networks. The study of this problem has been limited due to the non-convexity of the underlying optimization problems, that prohibits an efficient ...
  • Wongpiromsarn, Tichakorn; Uthaicharoenpong, Tawit; Wang, Yu; Frazzoli, Emilio; Wang, Danwei (Institute of Electrical and Electronics Engineers (IEEE), 2012-09)
    We propose a distributed algorithm for controlling traffic signals. Our algorithm is adapted from backpressure routing, which has been mainly applied to communication and power networks. We formally prove that our algorithm ...
  • Lapinski, Michael Tomasz; Berkson, Eric; Gill, Thomas; Reinold, Mike; Paradiso, Joseph A. (Institute of Electrical and Electronics Engineers, 2009-09)
    This paper introduces a compact, wireless, wearable system that measures signals indicative of forces, torques and other descriptive and evaluative features that the human body undergoes during bursts of extreme physical ...
  • Paltsev, Sergey; Rausch, Sebastian; Reilly, John M; Metcalf, Gilbert E (Berkeley Electronic Press, 2010-07)
    We analyze the distributional and efficiency impacts of different allowance allocation schemes motivated by recently proposed U.S. climate legislation for a national cap and trade system using a new dynamic computable ...
