Replacement Policies for a Proxy Cache
- DEIT, Univ. di Pisa. [Online]. Available: http://www.iet.unipi.it/~luigi/caching.ps. IEEE/ACM TRANSACTIONS ON NETWORKING
, 1996
"... Abstract—In this paper, we analyze access traces to a Web proxy, looking at statistical parameters to be used in the design of a replacement policy for documents held in the cache. In the first part of this paper, we present a number of properties of the lifetime and statistics of access to document ..."

, the value of a document is computed adaptively based on information readily available to the proxy server. The algorithm has no hardwired constants, and the computations associated with the replacement policy require only a small constant time. We show how LRV outperforms LRU and other policies and can
Supporting Adaptive Services in a Heterogeneous Mobile Environment
"... Future computer environments will include mobile computers which will either be disconnected, weakly interconnected by low speed wireless networks such as GSM, or fully inter-connected by high speed networks ranging from Ethernet to ATM. While the transition between networks is currently a heavyweig ..."

heavyweight operation we believe that developments in network interface technology will soon enable mobile computers to dynamically select their network service based on cost and performance requirements. Such flexibility, coupled with the inherent unreliability of mobile communications, means that system
Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance

VC funds whose parent firms enjoy more influential network positions have significantly better performance, as measured by the proportion of portfolio company investments that are successfully exited through an initial
Evaluation of Multicast Routing Algorithms for Real-Time Communication on High-Speed Networks
- IEEE Journal on Selected Areas in Communications
, 1997
"... Abstract—Multicast (MC) routing algorithms capable of sat-isfying the quality of service (QoS) requirements of real-time applications will be essential for future high-speed networks. We compare the performance of all of the important MC routing algorithms when applied to networks with asymmetric li ..."

Ultra-low power data storage for sensor networks
- In Proc. IEEE/ACM Information Processing in Sensor Networks (IPSN) - Track on Platforms, Tools and Design Methods for Networked Embedded Systems (SPOTS
, 2006
"... Local storage is required in many sensor network applications, both for archival of detailed event information, as well as to overcome sensor platform memory constraints. While extensive measurement studies have been performed to highlight the trade-off between computation and communication in senso ..."

in sensor networks, the role of storage has received little attention. The storage subsystems on currently available sensor platforms have not exploited technology trends, and consequently the energy cost of storage on these platforms is as high as that of communication. Current flash memories, however
Adaptive Sampling for Sensor Networks
- Proc. DMSN’04
, 2004
"... A distributed data-stream architecture finds application in sensor networks for monitoring environment and activities. In such a network, large numbers of sensors deliver continuous data to a central server. The rate at which the data is sampled at each sensor affects the communication resource and ..."

QoS-Assured Service Composition in Managed Service Overlay Networks
- ICDCS 2003
, 2003
"... Many value-added and content delivery services are being offered via service level agreements (SLAs). These services can be interconnected to form a service overlay network (SON) over the Internet. Service composition in SON has emerged as a cost-effective approach to quickly creating new services. ..."

. Previous research has addressed the reliability, adaptability, and compatibility issues for composed services. However, little has been done to manage generic quality-of-service (QoS) provisioning for composed services, based on the SLA contracts of individual services. In this paper, we present QUEST, a
