   abstract = {Although modularized protocol frameworks are flexible and adaptive to the increasing heterogeneity of networking environments, it remains a challenge to automatically compose communication stacks from protocol modules. The typical static classification into network layers or class hierarchies cannot appropriately accommodate cross-cutting changes such as overlay routing or cross-layer signaling. In this paper, we discuss how protocol composition can be driven by functionality and demand at runtime based on extensible semantic models of protocols and their execution environment. Such an approach allows to reason about the functionality and quality of automatically composed and adapted protocol compounds and it is open to existing and future protocols.},

The space and weight constraints resulting from the size of the animals have led to simple but functional approaches for vocalization classification and position estimation. For the resulting data we have developed novel, delay-tolerant routing and collection strategies. These are expected to be used in a sparse, dynamic network resulting from various rats being tagged with our nodes and running around freely - an area that will eventually be too big to be covered solely by stationary data sinks. Furthermore, the system is designed to extract information on the social interactions between animals from the routing data. It currently works in an indoor environment and we are preparing it for tests in a controlled outdoor setup.},

   abstract = {Structured Peer-to-Peer (P2P) systems are highly scalable, self-organizing, and support efficient lookups. Furthermore, Distributed Hash Tables (DHTs), due to their features, are used more and more for file-sharing and content distribution applications. However, a major weakness of traditional DHTs is the search for stored content, as data is assigned to nodes based on hash functions, and the very nature of hash tables allows only exact pattern matches. We present Cerco, a solution for the problem of range queries by using the principles of order-preserving DHTs and a hierarchically structured P2P approach. To guarantee an efficient routing and load balancing, Cerco uses a dynamic hierarchy of DHTs by creating subrings on demand and two explicit load balancing strategies. Our evaluation shows that Cerco is able to achieve the goals of supporting range queries, logarithmic-hop routing, and efficient load balancing.},

KleeNet generates a concrete test case with real input values identifying a specific error path in a program. Additionally, we show that KleeNet integrates well into TinyOS application development life cycle with minimum manual effort, making it easy for developers to test their applications.},

To leverage this coverage, sharing of access points as Internet uplinks among users has first become popular in communities of individuals and has recently been adopted as a business model by several companies. However, existing implementations and proposals suffer from the security risks of directly providing Internet access to strangers. In this paper, we present the P2P Wi-Fi Internet Sharing Architecture PISA, which eliminates these risks by introducing secure tunneling, cryptographic identities, and certificates as primary security concepts. Thus, PISA offers nomadic users the same security that they expect from a wired Internet connection at home. Based on its three fundamental mechanisms, PISA achieves a flexibility which opens significant advantages over existing systems. They include user mobility, anonymity, service levels with different performance and availability characteristics, and different revenue models for operators. With this combination of key features, PISA forms an essential basis for global, seamless, and secure Wi-Fi sharing for large communities.},

Unstable links, although often promising to be of large routing progress, are not considered for packet forwarding as link estimators typically cannot handle their dynamics. In this paper we introduce short-term link estimation to capture link dynamics at a high resolution in time and to identify when these render a link temporarily reliable or unreliable. We identify such dynamics based on packet overhearing, predict short-term availability and unavailability, and adapt neighbor tables, thereby enlarging the set of links useable by any routing algorithm. Additionally, we show that short-term link estimation integrates seamlessly into today's sensor network link estimators and routing protocols.},

   abstract = {Massively Multiplayer Online Games (MMOGs) have become increasingly popular in the last years. So far the distribution of load, caused by the players in these games, is not distributed dynamically. After the launch of a new game, the introduction of new content, during special ingame events, or also during normal operations, players tend to concentrate in certain regions of the game worlds and cause overload conditions. Therefore we propose the use of structured P2P technology for the server infrastructure of the MMOGs to improve the reliability and scalability. Previous work segmented the game work into rectangular areas; however this approach often split a group of players to different servers, causing additional overhead. This work presents a cluster-based Peer-to-Peer approach, which can be used for load balancing in MMOGs or in other virtual worlds. The system is able to dynamically adapt to the current state of the game and handle uneven distributions of the players in the game world. We show through simulation, also with traces from real online games, that the cluster-based approach performs better than the previous P2P-based systems, which split the world in rectangular areas.},

   abstract = {Network emulation, in which real systems interact with a network simulation, is a common evaluation method in computer networking research. Until now, the simulation in charge of representing the network has been required to be real-time capable, as otherwise a time drift between the simulation and the real network devices may occur and corrupt the results. In this paper, we present our work on synchronized network emulation. By adding a central synchronization entity and by virtualizing real systems for means of control, we can build-up network emulations which contain both unmodified x86 systems and network simulations of any complexity.},

   abstract = {In current Massively Multiplayer Online Games (MMOGs) the distribution of load is not distributed dynamically. But players tend to concentrate in certain regions of the game world and cause overload conditions. Therefore we propose the use of structured Peer-to-Peer technology for the server infrastructure of the MMOGs to improve the reliability and scalability. Previous work segmented the game work into rectangular areas but often split a group of players to different servers. This work presents a cluster-based P2P approach, which is able to dynamically adapt to the current state of the game and handle uneven distributions of players.Weshow through simulation, also with traces from real online games, that the cluster-based approach performs better than the previous P2P-based system.},

   abstract = {The rising complexity of data processing algorithms in sensor networks combined with their severely limited computing power necessitates an in-depth understanding of their temporal behavior. However, today only cycle accurate emulation and test-beds provide a detailed and accurate insight into the temporal behavior of sensor networks. In this paper we introduce fine grained, automated instrumentation of simulation models with cycle counts derived from sensor nodes and application binaries to provide detailed timing information. The presented approach bridges the gap between scalable but abstracting simulation and cycle accurate emulation for sensor network evaluation. By mapping device-specific code with simulation models, we can derive the time and duration a certain code line takes to get executed on a sensor node. Hence, eliminating the need to use expensive instruction-level emulators with limited speed and restricted scalability. Furthermore, the proposed design is not bound to a specific hardware platform, a major advantage compared to existing emulators. Our evaluation shows that the proposed technique achieves a timing accuracy of 99\% compared to emulation while adding only a small overhead. Concluding, it combines essential properties like accuracy, speed and scalability on a single simulation platform.},
