Deploying a wireless sensor network on an active volcano

Abstract: Augmenting heavy and power-hungry data collection equipment with lighten smaller wireless sensor network nodes leads to faster, larger deployments. Arrays comprising dozens of wireless sensor nodes are now possible, allowing scientific studies that aren't feasible with traditional instrumentation. Designing sensor networks to support volcanic studies requires addressing the high data rates and high data fidelity these studies demand. The authors' sensor-network application for volcanic data collection relies on triggered event detection and reliable data retrieval to meet bandwidth and data-quality demands.

Methods and systems for use in network management of content

Abstract: The present embodiments provide methods, systems and apparatuses for use in managing content on at least a local network. Some embodiments provide a method for use in managing content that detects there is a change to content on a local network, determines whether the change is additional content on a first client device, determines whether the additional content can be identified, determines whether there is a predictive distribution scheme when the additional content is identified, distributes the additional content over the local network according the predictive distribution scheme when a predictive distribution scheme applies to the additional content, determines whether a new predictive distribution scheme can be defined when a predictive distribution scheme does not apply to the additional content, and saving the new predictive distribution scheme when a new predictive scheme can be defined.

Big Questions in Public Network Management Research

Abstract: As the use of networks in public management increases, more and larger questions expand this research arena. In many ways, public network management is in search of a paradigm equivalent to the hierarchical-organizational authority paradigm of bureaucratic management. We raise and offer preliminary answers to seven metaquestions that address the nature of network management tasks, group process in collaboration, flexibil

Improving network management with software defined networking

Abstract: Network management is challenging. To operate, maintain, and secure a communication network, network operators must grapple with low-level vendor-specific configuration to implement complex high-level network policies. Despite many previous proposals to make networks easier to manage, many solutions to network management problems amount to stop-gap solutions because of the difficulty of changing the underlying infrastructure. The rigidity of the underlying infrastructure presents few possibilities for innovation or improvement, since network devices have generally been closed, proprietary, and vertically integrated. A new paradigm in networking, software defined networking (SDN), advocates separating the data plane and the control plane, making network switches in the data plane simple packet forwarding devices and leaving a logically centralized software program to control the behavior of the entire network. SDN introduces new possibilities for network management and configuration methods. In this article, we identify problems with the current state-of-the-art network configuration and management mechanisms and introduce mechanisms to improve various aspects of network management. We focus on three problems in network management: enabling frequent changes to network conditions and state, providing support for network configuration in a highlevel language, and providing better visibility and control over tasks for performing network diagnosis and troubleshooting. The technologies we describe enable network operators to implement a wide range of network policies in a high-level policy language and easily determine sources of performance problems. In addition to the systems themselves, we describe various prototype deployments in campus and home networks that demonstrate how SDN can improve common network management tasks.

Modeling Internet topology

Abstract: The topology of a network, or a group of networks such as the Internet, has a strong bearing on many management and performance issues. Good models of the topological structure of a network are essential for developing and analyzing internetworking technology. This article discusses how graph-based models can be used to represent the topology of large networks, particularly aspects of locality and hierarchy present in the Internet. Two implementations that generate networks whose topology resembles that of typical internetworks are described, together with publicly available source code.
