Abstract—Network Simulation is a predominant way of evaluating network performance of new routing algorithms and protocols. Discrete event simulation systems provide environments suitable for performance analysis. Dedicated simulation systems/small scale deployments of Delay-Tolerant Networks(DTN) are currently in use to explore the behavior and performance of Delay-Tolerant Networking Protocols and Architectures. The available simulation systems provide for varying system configurations at different levels of the protocol stack with the requirement for certain duplication/modification of the specified applications and protocols within the simulation environment. Also the simulation system depends on a flexible model of the developed system than the system itself. A real-world deployment discussed in [4] accommodates a link emulation system to provide a controlled environment for testing and analysis of Delay-Tolerant Networks. The development of a controlled test environment for deployment of a Delay-Tolerant Networking system requires significant infrastructure with complexities involving scalability and mobility. In this paper we present a scalable virtual networking test platform for deployment of delay-tolerant networks.

Abstract–The Internet Protocol Suite, although widely used in almost every application is ill-suited for use in communication systems characterized by unpredictable link reliability, intermittent network connectivity, very high round trip times (RTTs) and wide variations in data rates (also asymmetric). Challenges exist in the transfer of data between networks where the availability of an end-to-end path between the source and the destination may be absent. These issues are overcome by the use of Delay-Tolerant Networking (DTN) Architectures and Protocols. This paper presents the performance evaluation and analysis of such networks. The performance of DTN Bundling protocol is measured utilizing a variety of metrics under different network conditions and scenarios, thus providing a comprehensive characterization of such networks.

Abstract—Communication protocols today being extremely complex contain exhaustive definition and specification sets which need to be incorporated in the software implementations. As the information is difficult to comprehend, a visual model of the specifications provide a greater amount of clarity, thus leading to more efficient and bug-free implementations. A model driven approach to communication protocol design reduces significant development time and cost through automatic construction of the software from the visual design model. This paper presents a model driven architecture paradigm for design of Delay-Tolerant Network (DTN) Bundling Protocol. The design model formalism provides a well-defined structure which supports refactoring, event based modeling. The visual model also provides formalism for validation and verification of the design model. Models are designed using Object Management Group’s (OMG) model driven architecture core, Unified Modeling Language (UML). Furthermore, the protocol can be modeled using any language which supports state-transition semantics. The design can be modified to incorporate any of the four architectures suggested in the Bundle Protocol Specifications. Since UML is based on the object oriented methodology, translation of the state machines to the language of implementation is easily automated. The protocol interactions are modeled through the use of sequence and state diagrams This paper presents a methodology for designing and modeling the Delay Tolerant Network Bundling protocol. The methodology provides a common framework for use of the design with various suggested system architectural implementations. The automation in the implementation language also provides flexibility regarding the choice of the language itself.
