Slip surface localization in wireless sensor networks for landslide prediction
- …A landslide occurs when the balance between a hill’s weight and the countering resistance forces is tipped in favor of gravity. While the physics governing the interplay between these competing forces is fairly well understood, prediction of landslides has been hindered thus far by the lack of field…

An overlay architecture for high quality VoIP streams
- …Abstract — The cost savings and novel features associated with Voice over IP (VoIP) are driving its adoption by service providers. Unfortunately, the Internet’s best effort service model provides no quality of service guarantees. Because low latency and jitter is the key requirement for supporting h…

A Robust Routing Algorithm for Overlay Networks
- …A number of different Overlay network designs have been proposed to provide a large range of services ranging from content delivery and application-level multicast to robust data delivery in the presence of underlying network path outages and periods of degraded network performance. Previous work ha…

Gateway Design for Data Gathering Sensor Networks
- …Abstract—Innovation in gateways for data gathering sensor networks has lagged compared to advances in mote-class devices, leaving us with a limited set of options for deploying such systems. In this paper we outline the system design of a gateway that meets the hardware and software demands of data …

Measuring the Storm Worm Network
- …The Storm worm is a botnet which appeared in the early months of 2007. Its prolific growth, the use of decentralized command and control communication based on the Overnet P2P protocol and fast-flux servers for secondary-stage binary distribution, as well as the capability to aggressively defend its…

Scalable VPNs for the Global Information Grid
- …Abstract — Virtual Private Networks (VPNs) are the preferred mechanism for securing sensitive traffic crossing public networks. Traditionally, configuration of VPN gateways has been done manually. However, static configuration of gateways is particularly problematic within the context of the Global …

A Simple QoS Signaling Protocol for Mobile Hosts in the Integrated Services Internet
- …With advances in packet routing technology, and resource reservation protocols, the Internet is expected to provide ubiquitous integrated transport of speech, audio, video, and other real-time multimedia data in addition to the current best effort data traffic. Such integrated transport will also ne…

On the Use of Anycast in DNS
- …This paper attempts to fill a gap in our understanding of the Internet infrastructure: while anycast is deployed in many DNS zones, no studies exist that measure the performance impact of anycast in DNS. In this paper, we present results from our study of four top-level DNS zones, to evaluate the pe…

IRLSim: A General Purpose Packet Level Network Simulator
- …Simulation is the main tool for studying networking protocols before deploying them in a wide scale, or for understanding how they are expected to behave under various conditions. IRLSim is a new packet level network simulator that we developed in the hope to study several Internet protocols. From i…

Design Tools for Sensor-Based Science
- …We describe the architecture of software tools that aid scientists in designing and programming wireless sensor networks (WSNs). The goals of our system are (1) to reduce the complexity of deployment by automatically programming a sensor network and database based on a visual description of a site a…
