• Characterizing Heterogeneity in Cooperative Networks From a Resource Distribution View-Point 

      Abbas, Waseem; Egerstedt, Magnus (Georgia Institute of TechnologyInternational Press, 2014-11)
      A network of agents in which agents with a diverse set of resources or capabilities interact and coordinate with each other to accomplish various tasks constitutes a heterogeneous cooperative network. In this paper, we ...
    • Distribution of Agents in Heterogeneous Multi Agent Systems 

      Abbas, Waseem; Egerstedt, Magnus B. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2011-12)
      Heterogeneous multiagent systems are useful for performing various complex distributed tasks. The effectiveness and scope of service such systems provide, can be attributed to the distribution of agents of different types ...
    • Distribution of Agents with Multiple Capabilities in Heterogeneous Multiagent Networks – A Graph Theoretic View 

      Abbas, Waseem; Egerstedt, Magnus B. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2012-12)
      In this paper, we investigate how to distribute agents of different types in heterogeneous multiagent systems. Heterogeneity can for instance be related to various resources and capabilities agents may have. We insist that ...
    • Energy-Efficient Data Collection in Heterogeneous Wireless Sensor and Actor Networks 

      Abbas, Waseem; Jaleel, Hassan; Egerstedt, Magnus B. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2013-12)
      In this paper, we address the issue of activity scheduling of sensors in heterogeneous wireless sensor and actor networks (WSANs), thereby proposing an energy-efficient data collection scheme in such networks. In order ...
    • Hierarchical Assembly of Leader-Asymmetric, Single-Leader Networks 

      Abbas, Waseem; Egerstedt, Magnus B. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2011-06)
      The connection between leader-asymmetry and controllability in controlled agreement networks provides a topological, necessary condition for controllability. In this paper we investigate how to produce hierarchical networks ...
    • Robust Graph Topologies for Networked Systems 

      Abbas, Waseem; Egerstedt, Magnus B. (Georgia Institute of TechnologyElsevier, 2012-09)
      Robustness of networked systems against noise corruption and structural changes in an underlying network topology is a critical issue for a reliable performance. In this paper, we investigate this issue of robustness in ...
    • Securing Multiagent Systems Against a Sequence of Intruder Attacks 

      Abbas, Waseem; Egerstedt, Magnus B. (Georgia Institute of Technology, 2012-06)
      In this paper, we discuss the issue of security in multiagent systems in the context of their underlying graph structure that models the interconnections among agents. In particular, we investigate the minimum number of ...
    • A Tight Lower Bound on the Controllability of Networks with Multiple Leaders 

      Yazıcıoğlu, A. Yasin; Abbas, Waseem; Egerstedt, Magnus B. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2012-12)
      In this paper we study the controllability of networked systems with static network topologies using tools from algebraic graph theory. Each agent in the network acts in a decentralized fashion by updating its state in ...
