TL;DR: Current research challenges in ICN are described, including naming, security, routing, system scalability, mobility management, wireless networking, transport services, in-network caching, and network management.
Abstract: This memo describes research challenges for Information-Centric
Networking (ICN), an approach to evolve the Internet infrastructure to
directly support information distribution by introducing uniquely
named data as a core Internet principle. Data becomes independent from
location, application, storage, and means of transportation, enabling
or enhancing a number of desirable features, such as security, user
mobility, multicast, and in-network caching. Mechanisms for realizing
these benefits is the subject of ongoing research in the IRTF and
elsewhere. This document describes current research challenges in ICN,
including naming, security, routing, system scalability, mobility
management, wireless networking, transport services, in-network
caching, and network management. This document is a product of the
IRTF Information-Centric Networking Research Group (ICNRG).

25 Sep 2009TL;DR: The quest to find out what characterizes a potential killer applications for delay Tolerant Networking is embarked upon, which highlights some of the main challenges that needs to be solved to realize these applications and make DTNs a part of the mainstream network landscape.
Abstract: Delay Tolerant Networking (DTN) has attracted a lot of attention from the research community in recent years. Much work have been done regarding network architectures and algorithms for routing and forwarding in such networks. At the same time as many show enthusiasm for this exciting new research area there are also many sceptics, who question the usefulness of research in this area. In the past, we have seen other research areas become over-hyped and later die out as there was no killer app for them that made them useful in real scenarios. Real deployments of DTN systems have so far mostly been limited to a few niche scenarios, where they have been done as proof-of-concept field tests in research pro jects. In this paper, we embark upon a quest to find out what characterizes a potential killer applications for DTNs. Are there applications and situations where DTNs provide services that could not be achieved otherwise, or have potential to do it in a better way than other techniques? Further, we highlight some of the main challenges that needs to be solved to realize these applications and make DTNs a part of the mainstream network landscape.

TL;DR: In this paper, the authors investigated the effect of the optical fiber length on the performance of optical fiber for mm-wave generation in a radio-over-fiber (ROF) system.
Abstract: Stimulated Brillouin scattering (BS) in optical fibers is investigated for the generation of millimeter waves (mm-waves) for radio over fiber systems. Predictions of a numerical simulation are compared to experimental results, and both are in good agreement with each other. With the numerical simulation, the optimum parameter for the technique is calculated. It will be shown that the optimum length of the fiber for BS depends on the signal rather than on the pump power. This gives us the opportunity to adjust the parameters for any given fiber length. The advantages and limits of the proposed method for mm-wave generation are discussed.

13 Sep 2010TL;DR: This paper presents a simple local medium access control protocol, called JADE, for multi-hop wireless networks with a single channel that is provably robust against adaptive adversarial jamming and achieves an asymptotically optimal throughput if there is a sufficiently dense distribution of nodes.
Abstract: This paper presents a simple local medium access control protocol, called JADE, for multi-hop wireless networks with a single channel that is provably robust against adaptive adversarial jamming. The wireless network is modeled as a unit disk graph on a set of nodes distributed arbitrarily in the plane. In addition to these nodes, there are adversarial jammers that know the protocol and its entire history and that are allowed to jam the wireless channel at any node for an arbitrary (1 - e)-fraction of the time steps, where 0 < e < 1 is an arbitrary constant. We assume that the nodes cannot distinguish between jammed transmissions and collisions of regular messages. Nevertheless, we show that JADE achieves an asymptotically optimal throughput if there is a sufficiently dense distribution of nodes.

TL;DR: This work considers a pragmatic multi-layer capacity planning approach for an IP over optical network, which builds on existing planning practices and compute the savings achieved on two real-world core network models.
Abstract: We consider a pragmatic multi-layer capacity planning approach for an IP over optical network, which builds on existing planning practices. We first describe a router bypass process that considers the real impact of the IP layer topology change, given the actual behavior of the IP layer, leveraging a commercial IP planning tool. We then consider the design and cost impact of several multi-layer restoration schemes. We compute the savings achieved on two real-world core network models. The resulting savings are similar for both networks and are very promising.
