We exploit the lightweight and egocentric scheme of SimBet routing while at the same time taking the strength and the gradual aging of social relations into account and thereby increase the performance by one order of magnitude, especially in evolving network structures. We explore the model of similarity and betweenness over weighted graphs, and present a simulation on realistic traces from previous experiments, comparing our approach to the original SimBet, Epidemic Routing and Prophet.

Our contributions are two-fold as Horizon provides i) an API for accurately modeling processing time of discrete event simulation models by augmenting events with time spans and ii) a lightweight parallelization scheme that utilizes timing information to guide the parallel execution of simulations on multi-core computers. In this paper we primarily focus on the latter. horizon fileadmin/papers/2009/2009-kunz-mascots-horizon.pdf Poster Online IEEE Computer Society

Current link estimators focus mainly on identifying long-term stable links for routing, leaving out a potentiality large set of intermediate links offering significant routing progress. Fine-grained analysis of link qualities reveals that such intermediate links are bursty, i.e., stable in the short term. In this paper, we use short-term estimation of wireless links to accurately identify short-term stable periods of transmission on bursty links. Our approach allows a routing protocol to forward packets over bursty links if they offer better routing progress than long-term stable links. We integrate a Short Term Link Estimator and its associated routing strategy with a standard routing protocol for sensor networks. Our evaluation reveals an average of 22% reduction in the overall transmissions when routing over long-range bursty links. Our approach is not tied to any special routing protocol and integrates seamlessly with existing routing protocols and link estimators. wld fileadmin/papers/2009/2009-08-alizai-fgsn-bursty-routing.pdf doku.b.tu-harburg.de/volltexte/2009/581/pdf/proceedings.pdf Print Technical University Hamburg

Implementing or adapting the systems under test for such heterogeneous environments as network simulators, network emulators, testbeds, and end systems is immensely time and work intensive. In this paper, we present VIPE, a unified virtual platform for network experimentation, that slashes the porting effort. It allows to smoothly evolve a single implementation of a distributed system or protocol from its design up into its deployment by leveraging any form of network experimentation tool available. deployment, network experimentation, resource virtualization, simulation fileadmin/papers/2009/2009-landsiedel-visa-vipe.pdf Print ACM Press

ProMoX uses the Xen hypervisor to virtualize entire instances of operating systems which may execute any arbitrary protocol implementation. By utilizing system virtualization for external monitoring, ProMoX can transparently inspect any protocol state and performance metrics of protocol implementations carried by a guest operating system. This way, ProMoX supports both the indentification of faults within early prototypes as well as the evaluation of new protocol designs. Accepted for publication online EASST

While ns-2 has established itself as virtually the standard network simulation tool, other network simulators have gained more and more attention during the last years. In this paper, we briefly survey new developments in the field of network simulation and conduct a performance comparison study by implementing an identical simulation set-up in five simulators, namely ns-2, OMNet++, ns-3, SimPy and JiST/SWANS. Our results reveal large differences according to both run-time performance and memory usage. http://www.comsys.rwth-aachen.de/fileadmin/papers/2009/2009-weingaertner-simulator_comparison.pdf Print IEEE Proceedings of the IEEE International Conference on Communications 2009 (ICC 2009) Dresden, Germany en 1 EliasWeingaertner Hendrikvom Lehn KlausWehrle inproceedings 200906MobiArchgoetzprotocolorchestration 2009 43-50 The diversity of today's networking environments, such as wired, wireless, cell-based, or multi-hop, is matched by an equally large amount and heterogeneity of specialized protocols, e.g., overlays, Wi-Fi positioning, MANET routing, cross-layer signaling. However, communication is typically performed with a static set of protocols selected at design time based on simplified assumptions ignoring the environment's heterogeneity. In this paper, we argue that protocols can be orchestrated as software components driven purely by their functionality and the demands of the execution environment. Our end-system protocol framework Adapt bases on extensible ontological models that semantically describe protocol and environment properties. At runtime, each connection receives a custom-tailored protocol stack that Adapt orchestrates from the requirements derived from the application, user, and environment. With this approach, end-systems can reason about the functionality and quality of automatically composed and adapted protocol compounds while remaining open to existing and future protocols. https://www.comsys.rwth-aachen.de/fileadmin/papers/2009/2009-goetz-mobiarch-protocol-orchestration.pdf print Krzysztof Zielinski and Adam Wolisz and Jason Flinn and Anthony LaMarca ACM

They also inspect and filter traffic, detect network intrusion, control access to network resources, and enforce different levels of quality of service. The cornerstones for these security-related network services are end-host authentication and authorization. Using a cryptographic namespace for end-hosts simplifies these tasks since it gives them an explicit and verifiable identity. The Host Identity Protocol (HIP) is a key-exchange protocol that introduces such a cryptographic namespace for secure end-to-end communication. Although HIP was designed with middleboxes in mind, these cannot securely use its namespace because the on-path identity verification is susceptible to replay attacks. Moreover, the binding between HIP as an authentication protocol and IPsec as payload transport is insufficient because on-path middleboxes cannot securely map payload packets to a HIP association. In this paper, we propose to prevent replays attack by treating packet-forwarding middleboxes as first-class citizens that directly interact with end-hosts. Also we propose a method for strengthening the binding between the HIP authentication process and its payload channel with hash-chain-based authorization tokens for IPsec. Our solution allows on-path middleboxes to efficiently leverage cryptographic end-host identities and integrates cleanly into existing protocol standards. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2009/2009-heer-icc-end-host-authentication.pdf Print Piscataway, NJ, USA

It achieves these properties by introducing a new cryptographic namespace. This document specifies an extension for HIP that enables middleboxes to unambiguously verify the identities of hosts that communicate across them. This extension enables middleboxes to verify the liveness and freshness of a HIP association and, thus, enables reliable and secure access control in middleboxes.

This document specifies an extension for HIP that enables HIP end-hosts and HIP-aware middleboxes to announce services to HIP hosts during a HIP Base EXchange (BEX) or HIP update. Service providers are able to specify the type and requirements of a service; clients can then decide to agree on the terms of service. This allows the service provider to verify the accordance of the client with the service conditions while the client is able to verify the authenticity of the used service.
