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)
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)
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)
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 laptops and desktops. The vision is that FLIP will be used to interconnect such(More)
This paper evaluates FLIP, a flexible header protocol for power-constrained, heterogeneous networks. We show that FLIP can improve the energy efficiency of a system considerably, prolonging the system’s lifetime. For example, when employing FLIP to implement an existing sensor network communication paradigm, we obtain 50% energy savings when compared to the(More)
In contrast to today’s IP-based host-oriented Internet architecture, Information-Centric Networking (ICN) emphasizes content by making it directly addressable and routable. ContentCentric Networking (CCN) is an instance of ICN designed by PARC as a reference implementation that works in many environments from high-speed data centers to resource constrained(More)
