      In this paper we discuss new synchronization algorithms for Parallel and Distributed Discrete Event Simulations (PDES) which exploit the capabilities and behavior of the underlying communications network. Previous work ...
    • On Standardized Network Topologies For Network Resesrch 

      Riley, George F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2002-12)
      Simulation has become the evaluation method of choice for many areas of computer networking research. When designing new or revised transport protocols, queuing methods, routing protocols, (just to name a few), a common ...
    • An On-Demand Bluetooth Scatternet Formation and Routing Protocol for Wireless Sensor Networks 

      Zhang, Xin; Riley, George F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2005-05)
      Bluetooth is a promising short-range wireless communication technology with the characteristics of interference resilience and power efficiency which are required by wireless sensor networks. As an enhanced sensor node ...
    • Performance of Routing Protocols in Very Large-Scale Mobile Wireless Ad Hoc Networks 

      Zhang, Xin; Riley, George F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2005-09)
      As wireless devices become more and more popular, ad hoc networks grow in the number of nodes as well as the complexity of communication among the large number of nodes. However, due to the limitation of simulation ...
    • Scalable RTI-Based Parallel Simulation of Networks 

      Perumalla, Kalyan S.; Park, Alfred; Fujimoto, Richard M.; Riley, George F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2003-06)
      Federated simulation interfaces such as the High Level Architecture (HLA) were designed for interoperability, and as such are not traditionally associated with high performance computing. In this paper, we present ...
    • Simulating Internet Worms 

      Riley, George F.; Sharif, Monirul I.; Lee, Wenke (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2004-10)
      The accurate and efficient modeling of Internet worms is a particularly challenging task for network simulation tools. The atypical and aggressive behavior of these worms can easily consume excessive resources, both ...
