The κ factor: inferring protocol performance using inter-link reception correlation
Kannan Srinivasan,Mayank Jain,Jung-Il Choi,Tahir Azim,Edward S. Kim,Philip Levis,Bhaskar Krishnamachari +6 more
TL;DR: A new metric, κ, is presented that, unlike existing widely used metrics, has no bias based on the packet reception ratios of links and makes κ a better predictor of performance of opportunistic routing and network coding protocols.
Proceedings ArticleDOI
Whirlpool routing for mobility
TL;DR: The theoretical basis for WARP's behavior is provided, defining an "update area" in which the topology must adjust when a destination moves, and it is found that using the data plane for topology maintenance is highly effective due to the incremental nature of mobility updates.
Journal ArticleDOI
ReCache: reactive caching for fast analytics over heterogeneous data
TL;DR: ReCache is a cache-based performance accelerator that is reactive to the cost and heterogeneity of diverse raw data formats that reduces execution time over the entire workload by 19-75% compared to existing techniques.
Grid Enabled Analysis : Architecture, prototype and status
F. van Lingen,M. Thomas,Tahir Azim,I Chitnis,Ashiq Anjum,Dimitri Bourilkov,M Kulkarni,Conrad Steenberg,Richard Cavanaugh,Julian Bunn,J Ukin,Paul Avery,I. Legrand,Harvey B Newman +13 more
TL;DR: The Grid Analysis Environment (GAE), which is a continuation of the CAIGEE project [5], is an effort to develop, integrate and deploy a system for distributed analysis.
Proceedings ArticleDOI
The Clarens Web service framework for distributed scientific analysis in grid projects
F. van Lingen,Conrad Steenberg,Michael Thomas,Ashiq Anjum,Tahir Azim,Faisal Khan,H. Newman,Arshad Ali,Julian Bunn,I. Legrand +9 more
TL;DR: Some of the core functionality of Clarens that the authors believe is important for building distributed systems based on Web services that support scientific analysis are discussed.
