Fine-grained power modeling for smartphones using system call tracing
TLDR
We propose a new, system-call-based power modeling approach which gracefully encompasses both utilization-based and non-utilization- based power behavior. Expand

On the impact of packet spraying in data center networks
TLDR
A simple packet-level traffic splitting scheme called RPS not only leads to significantly better load balance and network utilization, but also incurs little packet reordering since it exploits the symmetry in these networks. Expand

The only constant is change: incorporating time-varying network reservations in data centers
TLDR
We propose a fine-grained virtual network abstraction, Time-Interleaved Virtual Clusters (TIVC), that models the time-varying nature of the networking requirement of cloud applications. Expand

Path planning of mobile landmarks for localization in wireless sensor networks
TLDR
We first study the localization error of three different trajectories for the mobile landmark equipped with a GPS unit and study the tradeoffs between the trajectory resolution and the localization accuracy in the presence of 2-hop localization. Expand

Performance comparison of scalable location services for geographic ad hoc routing
  • S. Das, H. Pucha, Y. Hu
  • Computer Science
  • Proceedings IEEE 24th Annual Joint Conference of…
  • 13 March 2005
TLDR
Geographic routing protocols allow stateless routing in mobile ad hoc networks (MANETs) by taking advantage of the location information of mobile nodes and thus are highly scalable. Expand
