          abstract={Content-Centric Networking (CCN) is a new paradigm for the future Internet where content is addressed by hierarchically organized names with the goal to replace TCP/IP networks. 
    Unlike IP addresses, names have arbitrary length and are larger than the four bytes of IPv4 addresses. 
    One important data structure in CCN is the Forwarding Information Base (FIB) where prefixes of names are stored together with the forwarding face. 
    Long prefixes create problems for memory constrained Internet of Things (IoT) devices. 
    In this work, we derive requirements for a FIB in the IoT and survey possible solutions. 
    We investigate, design and compare memory-efficient solutions for the FIB based on hashes and Bloom-Filters. 
    For large number of prefixes and an equal distribution of prefixes to faces we recommend a FIB implementation based on Bloom-Filters. 
    In all other cases, we recommend an implementation of the FIB with hashes.}

  sensor networks or vehicular ad-hoc networks. Recently, we have
  developed and designed a general purpose data dissemination protocol
  called AutoCast in this field that we evaluated in detail by
  simulations. When we started to use AutoCast in real applications, we
  found out that the description of AutoCast is incomplete, as we provided
  the algorithms of AutoCast in details but did neither provide nor
  describe a suitable Application Programming Interface (API) and AutoCast
  was closely coupled to the application. The focus of this article is
  twofold. First, we propose an appropriate API to encapsulate data
  dissemination protocols like AutoCast and we specify the service
  interface of AutoCast in detail. This API can serve as a reference model
  for other nature and biologically inspired data dissemination approaches
  and applications. Second, we evaluate two applications based on our API
  with AutoCast in the field of wireless sensor networks and vehicular
  ad-hoc networks to illustrate the usage of the API and demonstrate the

Current traffic monitoring and management approaches with stationary infrastructure lack flexibility with respect to system deployment and have difficulties with detecting unpredictable events (e.g., accidents). One goal of AutoNomos is the development of a distributed and selforganising traffic information and management system without a centralised infrastructure. Our system relies on a GPS-based navigation system and a wireless radio interface; vehicles can gather information about the current position on the road network and form a vehicular ad-hoc network (VANET) to share information about traffic phenomena. In this article, we introduce Hovering Data Clouds (HDCs) as a tool to collect, aggregate and disseminate application-specific data. HDCs evolve in a self-organising manner at locations of relevant data in the system. Although their data is hosted on the nodes, HDCs exist independent of the individual carriers. While HDCs float between physical carriers, their corresponding HDC messages are disseminated in the network by a new effective transport protocol named AutoCast, designed according to Organic Computing paradigms. Finally, we demonstrate that HDCs detect traffic phenomena reliably and propagate them robustly within the network.",

    abstract = {Today's Internet is approaching architectural limits that are set up by its legacy architecture. It is based on technologies and algorithms that were developed about 30 years ago. Thus intensive research is done in the field of new protocols and algorithms fulfilling the needs of the Future Internet. We believe that wireless sensor networks (WSNs), sensor-equipped devices such as cellphones and other embedded systems will have a vital part in this context, providing a way to obtain information about the real world. All of these new devices will produce a huge amount of data by sensing and interacting with their environment. At present, complex low-level sensor node programming and algorithm knowledge is necessary to access sensor data, and only a few mature techniques exist to integrate heterogeneous WSNs with the Internet. The goal of Real-World G-Lab, which is part of the German-Lab (G-Lab) project, is to overcome these obstacles by working on the different levels of protocols, services and applications. We will enable developers to write applications that rely on sensor data input, without knowledge of the underlying hardware platform and the network communication algorithms. This implies that sensors are able to participate in the Future Internet as peer hosts. This enables new fields of applications but likewise opens a set of new challenges in the context of efficient request processing by WSNs. Efficiency here means the optimization of query-latency, energy efficiency and general service-guarantees regarding the access to sensor nodes. Beyond this we need the ability to scale to a large amount of requests from the Internet while maintaining low latencies. We will verify our concepts and applications inside the controllable environment of the G-LAB research network, by adding several outdoor WSN deployments to the experimental facility of the G-LAB project. In summary, Real-World G-LAB will contribute to the integration of resource-constrained (wireless) sensor devices into the Future Internet by investigating several key challenges, ranging from low-level energy efficiency to improved high-level application development.},

  @inproceedings{bimschas2010smartgateways,
  	abstract={There is an increasing trend to integrate sensor networks into the Internet, eventually resulting in an Internet of Things. Recent efforts of porting IPv6 to sensor networks turn sensor nodes into equitable Internet peers and RESTful Web Services on sensor nodes allow a distribution of the application logic among sensor nodes and more powerful Internet nodes. The touching point between a sensor network and the Internet is the gateway which translates between the link-layer protocols used in the Internet (Ethernet, Wi-Fi) and sensor networks (IEEE 802.15.4). So far, the functionality of those gateways was fixed and simple. We propose to turn these gateways into smart gateways by enabling them to execute application code. As only the gateway has full knowledge of and control over both the sensor network and the Internet, smart gateways can act as performance-enhancing proxies and intelligent caches to preserve the limited resources of the sensor network. Also, the smart gateway can perform application-specific protocol conversion between highly optimized but non-standard protocols in the sensor network and standardized, but less efficient protocols in the Internet. In this paper we present the design of a middleware for smart gateways that allows the execution of application code on the gateway by offering simplified interfaces to the sensor network and the Internet. We also report preliminary performance results for key functions of the middleware.},

    abstract = {Simulations were standard in the Mobile Ad Hoc Network (MANET) research
  	community in the past. New protocols and algorithms were validated
  	via simulations by network simulators such as ns2 or GloMoSim. However,
  	even with the increasing number of published simulation papers, contradictory
  	results are decreasing the confidence in simulations today. First
  	experimental results show that simulation models for Ad Hoc networks
  	are far from being realistic and protocols developed in simulations
  	failed in real word environments. As a result, the demand for experimental
  	results and application deployments within the research community
  	increases. In this paper, we introduce FRED as a suitable application
  	to conduct protocol evaluations as well as user acceptance surveys.
  	FRED (Flexible Radio Enabled Dialog) is an enhanced TED-System that
  	allows asynchronous surveys or quizzes with a multi hop radio network,
  	where individual participants conduct the survey independent of others.
  	FRED is based on the pacemate sensor network platform that provides
  	a comfortable lightweight housing, a simple radio interface and an
  	intuitive GUI that allows long term evaluations of user acceptance
  	and network protocols.},
