    Welcome to Athens! On behalf of the whole organizing team, we wholeheartedly welcome you to the third installment of Valuetools, Valuetools 2008. The first two installments took place in Pisa (2006) and Nantes (2007). So, again, the conference is taking place in a city of rich cultural heritage. We look forward to emulating the previous two installments also in terms of their scientific success. The motivation behind Valuetools is the observation that an impressive range of methodologies and tools have been developed recently for the purpose of performance evaluation, across many disparate research fields. Valuetools is meant to be a forum that will allow researchers to compare and debate the full range of these tools and methodologies, and in addition promote the interdisciplinary flow of technical information.

    • NS-2 enhancements for detailed HSDPA simulations

      Research Article in 3rd International ICST Conference on Performance Evaluation Methodologies and Tools

      Abdulmohsen M. Mutairi, Uthman A. Baroudi

The main components of EURANE include the Radio Link Control (RLC) layer with the Acknowledged and Unacknowledged Modes, MAC layer for the main UMTS and HSDPA transport channels and a physical-layer simulation tool for simulating the fast channel variations in HSDPA. Although it has added most of the UMTS protocol stack to NS-2, EURANE does not support multiple cells, user mobility or handover which are necessary to study the system-level performance of RLC layer, handover and Iub flow control. In this paper, we describe new extensions and a redesign of EURANE to overcome these limitations and provide additional functionality. The new simulator supports user mobility using Random Waypoint mobility models and handover. In addition, the simulator provides an enhanced signaling protocol for Iub flow control that allow adding new flow control algorithms to EURANE whenever needed.

    • A new approach to simulating PHY, MAC and routing

In this paper, we discuss the new challenges that have arisen regarding the simulation of the wireless channel and the PHY, MAC and Routing layers, argumenting why currently available network simulation tools such as ns2 and many of its recently proposed extensions do not address all these issues in a comprehensive and systematic fashion. We then present a novel framework designed to address these challenges. This framework has been developed as an extension of NS-Miracle, in order to have support in the definition and management of scenarios involving the use of multiple interfaces and radio technologies, and is made up of two components. The first component is the Miracle PHY and MAC framework, which provides support for the development of Channel, PHY and MAC modules, providing support for features currently lacking in most state-of-the-art simulators, while at the same time giving a strong emphasis on code modularity, interoperability and reusability. The second component is the Miracle Routing framework, which enables the integration of different routing schemes in a multi-tier architecture to provide support for the simulation of multi-technology and heterogeneous networks. We want to observe that, thanks to this framework, it is now possible to carefully simulate complex network architectures potentially at all the OSI layers, from the physical reception model to standard applications and system management schemes. This allows to have both a comprehensive view of all the networks interactions and its high level view, which plays an important role in many research investigation area, such as cognitive networking and cross-layer design.

    • XAV: a tracing framework for exploring large network simulation outputs

Visual exploration allows users to search through simulation traces by using multidimensional representations of the network in an intuitive and interactive way. To speed up trace file exploration, we propose to store the simulation events according a format, namely XAV, that i) exploits the multidimensional nature of users requests and ii) allows quick identification of the packet paths through the network. XAV files are stored in a database to simplify data manipulation. The XAV tracing framework has been implemented in the NS-2 simulator and tested over a wireless ad-hoc network composed of 25 nodes. The performance evaluation shows that XAV enables to extract about 1000 packet paths per second from 100 MB trace files.

    • Consensus in inventory games

Information available to each player concerning the other players' strategies evolves in time. At each stage (time period), the players select myopically their best binary strategy on the basis of a payoff, defined on a single stage, monotonically decreasing with the number of active players. The game is specialized to an inventory application, where fixed costs are shared among all retailers, interested in reordering or not from a common warehouse. As information evolves in time, the number of active players changes too, and then each player adjusts its strategy at each stage based on the updated information. In particular, the authors focus on Pareto optimality as a measure of coordination of reordering strategies, proving that there exists a unique Pareto optimal Nash equilibrium which verifies certain stability conditions. The main contribution of the paper is the design of a consensus protocol allowing the distributed convergence of the strategies to the unique Pareto optimal Nash equilibrium. Results may also be extended to externality games, pollution/congestion games, and cost-sharing games, with the only constraint of being the strategies binary and with threshold structure.

The important mechanisms for IEEE 802.11 in our module are multi-channel, directional antennas, multiple interfaces, L2-handoff, L2-trigger, bicasting, pre-established LSP, and buffering mechanism. MPLS modules used in this simulator is based on MPLS module (MNS) [8]-[10]. This simulator could be configured to assess performance of Mobile MPLS protocols such as micro mobility-enabled multiprotocol label switching (M-MPLS) [21], fast handoff (FH) and master forwarding chain (MFC)-Micro Mobile MPLS [2], [23] and MiM-MPLS [30]. The simulator is validated for each mechanism. The validation results follow to the theory.
