Detecting node failures within Peer-to-Peer networks is an inherent trade-off between timely detection and consuming bandwidth on network maintenance. In the absence of user-driven messages, the majority of P2P networks rely upon the exchange of periodic keep-alive messages to maintain connections and network topology. We investigate three novel algorithms which ...

As the scale of Distributed Virtual Environments (DVEs) grows in terms of participants and virtual entities, using interest management schemes to reduce bandwidth consumption becomes increasingly common for DVE development. The interest matching process is essential for most of the interest management schemes which determines what data should be sent ...

Groundwater is like dark matter--we know very little apart from the fact that it is hugely important. Given the scarcity of data, mathematical modelling can come to the rescue but existing groundwater models are mainly restricted to simulate the transport and degradation of contaminants on the scale of whole contaminated ...

Range-Query is an important associative form of data access in distributed simulations and Distributed Virtual Environments. This paper discusses the problem of Range-Queries in the context of distributed simulation of multi-agent systems. An algorithm is presented for performing instantaneous Queries within an optimistic synchronisation framework and in the presence of ...

The use of learning objects (LOs) to support learning processes is considered a key factor in the deployment of e-learning frameworks. Although their discrete and self-contained nature offers many advantages LOs have presented courseware designers with two fundamental issues. The first issue concerns the adequate identification of the learning objects ...

Interest management provides scalable data distribution for large-scale distributed virtual environments by filtering irrelevant messages on the network. The interest matching process is essential for most of the interest management schemes which determines what data should be sent to the participants as well as what data should be filtered. Most ...

Historical studies are frequently perceived to be characterised as clear narratives defined by a series of fixed events or actions. In reality, even where critical historic events may be identified, historic documentation frequently lacks corroborative detail that supports verifiable interpretation. Consequently, for many periods and areas of research, interpretation may ...

A large scale High Level Architecture (HLA)-based simulation can be constructed using a network of simulation federations to form a ''federation community''. This effort is often for the sake of enhancing scalability, interoperability, composability and enabling information security. Synchronization mechanisms are essential to coordinate the execution of federates and event ...

Collusion attacks remain a major problem of reputation and trust models, in mobile ad hoc networks. By covering up malicious behaviour of one another from the remaining part of the network, two or more malicious nodes may collaborate to cause damage to or disrupt the network. A number of models ...

Interest management is essential for real-time large-scale distributed virtual environments (DVEs) which seeks to filter irrelevant messages on the network. Many existing interest management schemes such as HLA DDM focus on providing precise message filtering mechanisms. However, this leads to a second problem: the computational overhead of the interest matching ...

In previous work we presented the DTRD algorithm, an optimistic synchronization algorithm for parallel discrete event simulation of multi-agent systems, and showed that it outperforms Time Warp and time windows on a range of test cases. DTRD uses a decision-theoretic model of rollback to derive an optimal time to delay ...

The application of distributed simulation techniques to ever more complex problems calls for more computational power. The emergence of the Grid provides an opportunity to address this challenge and thus make advances in the modelling and analysis of large-scale systems by harnessing the power of many computers. These requirements are ...

Distributed simulation has emerged as an important instrument for studying large-scale complex systems. Such systems inherently consist of a large number of components, which operate in a large shared state space interacting with it in highly dynamic and unpredictable ways. Optimising access to the shared state space is crucial for ...

In large, real-time interactive distributed systems such as Distributed Simulations and Multiplayer games, Interest Management (IM) is often implemented using a cell-based paradigm. In such a paradigm the subscription patterns of interactive clients are mapped on to some set of disjoint regions or cells which are typically hosted within a ...

P2P systems have witnessed phenomenal development in recent years. Evaluating and analyzing new and existing algorithms and techniques is a key issue for developers of P2P systems. In this context, simulation is an important tool for P2P developers. However, such systems are often very large and few existing simulators offer ...

We present a detailed analysis of the performance of the Decision Theoretic Read Delay (DTRD) optimistic synchronization algorithm for simulations of multi-agent systems (MAS). We develop an abstract characterization of the access patterns found in MAS simulations based on the simulation's degree of coupling and skew. Using this characterization, we ...

Distributed hash tables (DHTs) often maintain additional routing information regarding each node's surrounding neighbors within a network overlay. Sequential neighbors play a critical role in network recovery, providing alternative routes thus allowing more flexible and robust routing around a overlay. This paper details our analysis of a existing DHT routing ...

Large, experimental multi-agent system (MAS) simulations are highly demanding tasks, both computationally and developmentally. Agent toolkits provide reliable templates for the design of even the largest MAS simulations, without offering a solution to computational limitations. Conversely, distributed simulation architectures offer performance benefits, but the introduction of parallel logic can complicate ...
