The IMS Playground was extended appropriately to be used on top of new access networks as well as to provide new seamless multimedia applications. The FOKUS testbed originated from own developments as well as major industry players, and is being used by academic and industrial partners for prototyping new IMS related components, protocols, and applications. The next target is to integrate FOKUS testbed in a Pan-European Network of testbeds in order to reach a broader community with the benefits of such a testbeds federation. This paper describes the FOKUS experiences at running the IMS Playground, providing a look into administrative and technical issues that need consideration on integrating testbeds. This view can be applied to run any kind of testbed. The paper presents the descriptions of the issues from service/capabilities offer to test execution, as well as the intrinsic benefits and challenges.","PeriodicalId":397239,"journal":{"name":"2007 3rd International Conference on Testbeds and Research Infrastructure for the Development of Networks and Communities","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121962021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We elucidate the challenges that we faced and the design decisions that we had to make, sometimes based on technical reasons, and other times due to practicalities. These design challenges involve: (a) accessibility to the software, in order to be able to modify and implement various functionalities, (b) physical extendability, in order to add hardware in the future and, (c) manageability, in order to configure and update the software easily and quickly, for all the nodes in the network. We justify the hardware and software design choices that we make in order to facilitate these requirements. For ease of maintenance and convenience, each node is diskless, and we utilize power-over-ethernet through an Ethernet connection with a central server. We ensure that the software can be easily modified; this provides for easier module implementation and parameter tuning. We explain the different ways of node deployment, decisions that we make on power settings and discuss how and why the receiver sensitivity affects deployment decisions. Finally, we present our observations based on a set of measurements to quantify the stability of the links in our testbed.","PeriodicalId":397239,"journal":{"name":"2007 3rd International Conference on Testbeds and Research Infrastructure for the Development of Networks and Communities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125810241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chowkidar: A Health Monitor for Wireless Sensor Network Testbeds Chowkidar:无线传感器网络试验台的健康监视器

Sensor data collected in the field can be replayed on nodes, and new ways to process the data can be tested easily. Testbeds are rapidly growing in size, with hundreds or thousands of devices, and testbed services are also becoming richer and more complex. Due to their size and complexity, faults can (and do) occur in these testbeds, affecting the outcomes of experiments. Awareness of testbed health status is important to both testbed administrators charged with maintaining functional services, and users who prefer to use healthy devices and like to know if there are any failures during their experiments. Based on our experience with Kansei, a large WSN testbed at Ohio State, we identify use cases that motivate the design of Chowkidar, a health monitoring facility. Key among these are: monitoring as a service that operates independently of users to provide up-to-date testbed status information; monitoring of heterogeneous testbed devices and networks; distinguishing between node and interface failures; and diagnosing common-mode failures such as power supply or Ethernet hub failure. We present in this paper, a centralized and a distributed Chowkidar protocol that reliably monitor the health of large, heterogenous WSN testbeds. We present experimentally measured Chowkidar performance as well as real experiences and lessons learnt from the integration of Chowkidar with Kansei, including feedback from both testbed users and administrators who have found Chowkidar to be a useful tool for improving the accuracy and efficiency of testbed experimentation and maintenance.","PeriodicalId":397239,"journal":{"name":"2007 3rd International Conference on Testbeds and Research Infrastructure for the Development of Networks and Communities","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114770001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IP multimedia subsystem (IMS) defined by the 3rd generation partnership projects (3GPP and 3GPP2) represents today a basis framework for a service delivery platform (SDP) for providing triple play services. Several approaches have already been introduced struggling with the need for an integrated solution based on the IMS core or the development of a separated subsystem. The Fraunhofer Institute FOKUS has launched the \"Open IMS Playground\" in July 2004 as part of the German 3G beyond national testbed. The IMS Playground has been extended recently as an open environment gathering all major IMS core components, and triple play toolkit originating from own developments as well as major industry players, which can be used by academic and industrial partners for early prototyping of new triple play services, related components, protocols, and applications.

However, this may affect the functioning of all the applications and traditional protocols, worsening the already known problems with wireless connections and requiring the design and evaluation of novel solutions. Scenarios involving high mobility can be very complex; think, for instance, to a realistic case involving several nodes, representing people and cars moving under the coverage of several base stations. Since the geographical width and the number of involved nodes in such a scenario, simulations represent a fundamental tool to analyze the state of the art and newly proposed solutions. Unfortunately, modeling mobility with the most popular network simulator in the scientific community (i.e., NS-2) is not an easy task as its handoff mechanism appears faulty when coupled with a realistic model for wireless transmissions. In this paper, we discuss this problem and propose a new simulation module for mobile IP able to guarantee smooth handoffs even with realistic simulation set-ups.","PeriodicalId":397239,"journal":{"name":"2007 3rd International Conference on Testbeds and Research Infrastructure for the Development of Networks and Communities","volume":"425 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133209358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
