• Application acceleration for wireless and mobile data networks 

      Zhuang, Zhenyun (Georgia Institute of Technology, 2010-08-27)
      This work studies application acceleration for wireless and mobile data networks. The problem of accelerating application can be addressed along multiple dimensions. The first dimension is advanced network protocol design, ...
    • The Energy-Limited Capacity of Wireless Networks 

      Zhao, Wenrui; Ammar, Mostafa H. (Mostafa Hamed); Zegura, Ellen W. (Georgia Institute of Technology, 2004)
      The performance of large-scale wireless ad hoc networks is often limited by the broadcasting nature of the wireless medium and the inherent node energy constraints. While the impact of the former on network capacity has ...
    • Message Ferries as Generalized Dominating Sets in Intermittently Connected Mobile Networks 

      Ammar, Mostafa H.; Polat, Bahadir K.; Sachdeva, Pushkar; Zegura, Ellen W. (Georgia Institute of Technology, 2009)
      Message ferrying is a technique for routing data in wireless and mobile networks in which one or more mobile nodes are tasked with storing and carrying data between sources and destinations. To achieve connectivity between ...
    • Routing in Space and Time in Networks with Predictable Mobility 

      Merugu, Shashidhar; Ammar, Mostafa H. (Mostafa Hamed); Zegura, Ellen W. (Georgia Institute of Technology, 2004)
      We consider the problem of routing in emerging wireless networks where nodes move around explicitly carrying messages to facilitate communication in an otherwise partitioned network. The absence of a path at any instant ...
    • Trading Latency for Energy in Wireless Ad Hoc Networks using Message Ferrying 

      Jun, Hyewon; Zhao, Wenrui; Ammar, Mostafa H. (Mostafa Hamed); Zegura, Ellen W.; Lee, Chungki (Georgia Institute of Technology, 2004)
      Power management is a critical issue in wireless ad hoc networks where the energy supply is limited. In this paper, we investigate a routing paradigm, Message Ferrying (MF), to save energy while trading off data delivery ...
    • Ultra-mobile computing: adapting network protocol and algorithms for smartphones and tablets 

      Sanadhya, Shruti (Georgia Institute of Technology, 2013-11-15)
      Smartphones and tablets have been growing in popularity. These ultra mobile devices bring in new challenges for efficient network operations because of their mobility, resource constraints and richness of features. There ...
    • WTF? Locating Performance Problems in Home Networks 

      Sundaresan, Srikanth; Grunenberger, Yan; Feamster, Nick; Papagiannaki, Dina; Levin, Dave; Teixeira, Renata (Georgia Institute of Technology, 2013)
      Most users of home networks have experienced the intense frustration that comes with diagnosing poor performance. Even determining something as simple as whether a performance problem lies with the ISP or somewhere in ...
