Chord: A scalable peer-to-peer lookup service for internet applications
TLDR
Results from theoretical analysis, simulations, and experiments show that Chord is scalable, with communication cost and the state maintained by each node scaling logarithmically with the number of Chord nodes. Expand
OpenFlow: enabling innovation in campus networks
This whitepaper proposes OpenFlow: a way for researchers to run experimental protocols in the networks they use every day. OpenFlow is based on an Ethernet switch, with an internal flow-table, and aExpand
Resilient overlay networks
TLDR
It is found that forwarding packets via at most one intermediate RON node is sufficient to overcome faults and improve performance in most cases, demonstrating the benefits of moving some of the control over routing into the hands of end-systems. Expand
Adaptive protocols for information dissemination in wireless sensor networks
TLDR
It is found that the SPIN protocols can deliver 60% more data for a given amount of energy than conventional approaches, and that, in terms of dissemination rate and energy usage, the SPlN protocols perform close to the theoretical optimum. Expand
The Cricket location-support system
TLDR
The randomized algorithm used by beacons to transmit information, the use of concurrent radio and ultrasonic signals to infer distance, the listener inference algorithms to overcome multipath and interference, and practical beacon configuration and positioning techniques that improve accuracy are described. Expand
CryptDB: protecting confidentiality with encrypted query processing
TLDR
The evaluation shows that CryptDB has low overhead, reducing throughput by 14.5% for phpBB, a web forum application, and by 26% for queries from TPC-C, compared to unmodified MySQL. Expand
Span: An Energy-Efficient Coordination Algorithm for Topology Maintenance in Ad Hoc Wireless Networks
TLDR
A randomized algorithm where coordinators rotate with time is given, demonstrating how localized node decisions lead to a connected, capacity-preserving global topology. Expand
Span: An energy-efficient coordination algorithm for topology maintenance in Ad Hoc wireless networks
TLDR
A randomized algorithm where coordinators rotate with time is given, demonstrating how localized node decisions lead to a connected, capacity-preserving global topology. Expand
Cutting the electric bill for internet-scale systems
TLDR
The variation due to fluctuating electricity prices is characterized and it is argued that existing distributed systems should be able to exploit this variation for significant economic gains. Expand
A comparison of mechanisms for improving TCP performance over wireless links
TLDR
The results show that a reliable link-layer protocol with some knowledge of TCP provides very good performance, and it is possible to achieve good performance without splitting the end-to-end connection at the base station. Expand
