This paper describes an experiment performed on Wide Area Network to assess and fairly compare the Quality of Service provided by a large family of failure detectors. Failure dete...
Analyzing TCP operation over 802.11 multihop ad hoc networks involves a cross-layer study. In this work, we investigate the effect of congestion and MAC contention on the interact...
We study a wireless network under the 802.11 random access protocol, supporting multiple physical layer rates. Based on models for the effective packet rates achieved at the MAC ...
Abstract—In hierarchical mobile ad hoc networks, the architectual stability is a key factor in determining the network performance. There are many solutions proposed to construct...
We describe the design and implementation of a high performance cloud that we have used to archive, analyze and mine large distributed data sets. By a cloud, we mean an infrastruc...
