SEP: A Stable Election Protocol for clustered heterogeneous wireless sensor networks
We study the impact of heterogeneity of nodes, in terms of their energy, in wireless sensor networks that are hierarchically clustered. In these networks some of the nodes become cluster heads,Expand

Self-similarity in World Wide Web traffic: evidence and possible causes
Recently the notion of self-similarity has been shown to apply to wide-area and local-area network traffic. In this paper we examine the mechanisms that give rise to the self-similarity of networkExpand

Self-similarity in World Wide Web traffic: evidence and possible causes
The notion of self-similarity has been shown to apply to wide-area and local-area network traffic. We show evidence that the subset of network traffic that is due to World Wide Web (WWW) transfersExpand

Characterizing reference locality in the WWW
The authors propose models for both temporal and spatial locality of reference in streams of requests arriving at Web servers. They show that simple models based on document popularity alone areExpand

Statistical rate monotonic scheduling
Statistical rate monotonic scheduling (SRMS) is a generalization of the classical RMS results of C. Liu and J. Layland (1973) for periodic tasks with highly variable execution times and statisticalExpand

A hierarchical characterization of a live streaming media workload
We present a thorough characterization of what we believe to be the first significant live Internet streaming media workload in the scientific literature. Our characterization of over 3.5 millionExpand

Popularity-aware greedy dual-size Web proxy caching algorithms
Web caching aims at reducing network traffic, server load and user-perceived retrieval delays by replicating popular content on proxy caches that are strategically placed within the network. WhileExpand

Using speculation to reduce server load and service time on the WWW
Abstract Speculative service implies that a client''s request for a document is serviced by sending, in addition to the document requested, a number of other documents that the server speculates willExpand
