This paper explores in-network aggregation as a power-efficient mechanism for collecting data in wireless sensor networks. In particular, we focus on sensor network scenarios where a large number of nodes nodes produce data periodically which is consumed by a sink node. Such communication model is typical of monitoring scenarios, one key application of(More)
Interconnecting heterogeneous devices, that is, devices with varying capabilities, has raised new challenges in the design of network protocols. This paper describes the design of the Flexible Interconnecting Protocol, or FLIP, whose goal is to interconnect heterogeneous devices. FLIP is a flexible protocol that addresses the needs of heterogeneous(More)
There is a growing need for developing high-throughput tools for crop phenotyping that would increase the rate of genetic improvement. In most cases, the indicators used for this purpose are related with canopy structure (often acquired with RGB cameras and multispectral sensors allowing the calculation of NDVI), but using approaches related with the crop(More)
This paper introduces an energy-efficient data collection technique that takes advantage of spatial/temporal data correlation to generate maps for continuous monitoring (e.g., of environmental conditions such as temperature, humidity, etc.). In its essence, the proposed technique, isoline aggregation, works by detecting isolines which are the lines that(More)
Content dissemination in disrupted networks poses a big challenge, given that the current routing architectures of ad hoc networks require establishing routes from sources to destinations before content can disseminated between them. In ad hoc networks subject to disruption, lack of reliable connectivity between producers and consumers of information makes(More)
This paper describes the Flexible Interconnection Protocol , or FLIP, whose main goal is to allow interconnection of heterogeneous devices with varying power, processing , and communication capabilities, ranging from simple sensors to more powerful computing devices such as lap-tops and desktops. The vision is that FLIP will be used to interconnect such(More)
