BCube: a high performance, server-centric network architecture for modular data centers
TLDR
Experiments in the testbed demonstrate that BCube is fault tolerant and load balancing and it significantly accelerates representative bandwidth-intensive applications. Expand
Dcell: a scalable and fault-tolerant network structure for data centers
TLDR
Results from theoretical analysis, simulations, and experiments show that DCell is a viable interconnection structure for data centers and can be incrementally expanded and a partial DCell provides the same appealing features. Expand
A two-tier data dissemination model for large-scale wireless sensor networks
TLDR
This paper describes TTDD, a Two-Tier Data Dissemination approach that provides scalable and efficient data delivery to multiple mobile sinks and evaluates TTDD performance through both analysis and extensive simulation experiments. Expand
Robust rate adaptation for 802.11 wireless networks
TLDR
This paper designs and implements a new Robust Rate Adaptation Algorithm (RRAA), which uses short-term loss ratio to opportunistically guide its rate change decisions, and an adaptive RTS filter to prevent collision losses from triggering rate decrease. Expand
Statistical en-route filtering of injected false data in sensor networks
TLDR
The results show that SEF can be implemented efficiently in sensor nodes as small as Mica2, and can drop up to 70% of bogus reports injected by a compromised node within five hops, and reduce energy consumption by 65% or more in many cases. Expand
PEAS: a robust energy conserving protocol for long-lived sensor networks
TLDR
A robust energy-conserving protocol that can build long-lived, resilient sensor networks using a very large number of small sensors with short battery lifetime, PEAS can extend a sensor network's functioning time in linear proportion to the deployed sensor population. Expand
The impact of multihop wireless channel on TCP throughput and loss
TLDR
This paper studies TCP performance over multihop wireless networks that use the IEEE 802.11 protocol as the access method and proposes two techniques, link RED and adaptive pacing, through which it is able to improve TCP throughput by 5% to 30% in various simulated topologies. Expand
UCAN: a unified cellular and ad-hoc network architecture
TLDR
This paper proposes the Unified Cellular and Ad-Hoc Network (UCAN) architecture for enhancing cell throughput, while maintaining fairness, and refine the 3G base station scheduling algorithm so that the throughput gains of active clients are distributed proportional to their average channel rate. Expand
TTDD: Two-Tier Data Dissemination in Large-Scale Wireless Sensor Networks
TLDR
TTDD is described, a Two-Tier Data Dissemination approach that provides scalable and efficient data delivery to multiple, mobile sinks that handles sink mobility effectively with performance comparable with that of stationary sinks. Expand
GRAdient Broadcast: A Robust Data Delivery Protocol for Large Scale Sensor Networks
TLDR
The analysis shows quantitatively the advantage of interleaved mesh over multiple parallel paths and shows that GRAB can successfully deliver over 90% of packets with relatively low energy cost, even under the adverse conditions of 30% node failures compounded with 15% link message losses. Expand
