Adaptive clustering for mobile wireless networks
- IEEE Journal on Selected Areas in Communications
, 1997
"... This paper describes a self-organizing, multihop, mobile radio network, which relies on a code division access scheme for multimedia support. In the proposed network architecture, nodes are organized into nonoverlapping clusters. The clusters are independently controlled and are dynamically reconfig ..."

HEED: A Hybrid, Energy-Efficient, Distributed Clustering Approach for Ad Hoc Sensor Networks
- IEEE TRANS. MOBILE COMPUTING
, 2004
"... Topology control in a sensor network balances load on sensor nodes and increases network scalability and lifetime. Clustering sensor nodes is an effective topology control approach. In this paper, we propose a novel distributed clustering approach for long-lived ad hoc sensor networks. Our proposed ..."

Memory Bandwidth Aware Scheduling for SMP Cluster Nodes
- In PDP ’05: Proceedings of the 13th Euromicro Conference on Parallel, Distributed and Network-Based Processing
, 2005
"... Clusters of SMPs are becoming increasingly common. However, the shared memory design of SMPs and the consequential contention between system processors for access to main memory can limit their efficiency significantly. Moreover, the continuous improvement of modern cluster interconnection technolog ..."

technologies leads to the network bandwidth being a significant fraction of the total memory bandwidth of the machine, thus the NIC of an SMP cluster node can also become a major consumer of shared memory bus bandwidth. In this paper we first provide experimental evidence that contention on the shared memory
An Energy-Efficient MAC Protocol for Wireless Sensor Networks
, 2002
"... This paper proposes S-MAC, a medium-access control (MAC) protocol designed for wireless sensor networks. Wireless sensor networks use battery-operated computing and sensing devices. A network of these devices will collaborate for a common application such as environmental monitoring. We expect senso ..."

in listening to an idle channel, nodes periodically sleep. Neighboring nodes form virtual clusters to auto-synchronize on sleep schedules. Inspired by PAMAS, S-MAC also sets the radio to sleep during transmissions of other nodes. Unlike PAMAS, it only uses in-channel signaling. Finally, S-MAC applies message

sensor networks to be deployed in an ad hoc fashion, with nodes remaining largely inactive for long time, but becoming suddenly active when something is detected. These characteristics of sensor networks and applications motivate a MAC that is different from traditional wireless MACs such as IEEE 802
Vogels, U-Net: a user-level network interface for parallel and distributed computing, in:
- Proceedings of the 15th ACM Symposium on Operating System Principles, ACM,
, 1995
"... Abstract The U-Net communication architecture provides processes with a virtual view of a network device to enable user-level access to high-speed communication devices. The architecture, implemented on standard workstations using off-the-shelf ATM communication hardware, removes the kernel from th ..."

, as well as novel abstractions like Active Message can be implemented efficiently. A U-Net prototype on an 8-node ATM cluster of standard workstations achieves 15Mbytes/s TCP bandwidth with 1Kbyte buffers and demonstrates performance equivalent to Meiko CS-2 and TMC CM-5 supercomputers on a set of Split
Network Coding for Large Scale Content Distribution
"... We propose a new scheme for content distribution of large files that is based on network coding. With network coding, each node of the distribution network is able to generate and transmit encoded blocks of information. The randomization introduced by the coding process eases the scheduling of bloc ..."

We study the performance of network coding in heterogeneous networks with dynamic node arrival and departure patterns, clustered topologies, and when incentive mechanisms to discourage free
Measurement and Analysis of Online Social Networks
- In Proceedings of the 5th ACM/USENIX Internet Measurement Conference (IMC’07
, 2007
"... Online social networking sites like Orkut, YouTube, and Flickr are among the most popular sites on the Internet. Users of these sites form a social network, which provides a powerful means of sharing, organizing, and finding content and contacts. The popularity of these sites provides an opportunity ..."

PVFS: A Parallel File System For Linux Clusters
- IN PROCEEDINGS OF THE 4TH ANNUAL LINUX SHOWCASE AND CONFERENCE
, 2000
"... As Linux clusters have matured as platforms for low-cost, high-performance parallel computing, software packages to provide many key services have emerged, especially in areas such as message passing and networking. One area devoid of support, however, has been parallel file systems, which are criti ..."
