Command and Control (C2) system and its interfacethe Common Operational Picture (COP) are main means that supports commander in its decision making process. COP contains information about friendly and enemy unit positions. The friendly position is gathered via tactical network. In the case of tactical network failure the information about units are not available. The tactical simulator can be u...

Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem.  Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...

Network on Chip (NoC) is a new paradigm for designing large and complex systems on chips (SoCs). In this paradigm, a packet switched network is provided for on-chip communication among cores. NoC paradigm provides the required scalability and reusability to reduce design time of SoCs. A NoC simulator is an important tool required to support development of designs based on a NoC architecture. In...

The Enhanced UMTS Radio Access Network Extensions (EURANE) provided UMTS and HSDPA support in the Network Simulator (NS-2). 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. Altho...

We present in this paper PETFEN, a Performance Evaluation Tool for Flow-level network modeling of Ethernet Networks. Flow-level network models are a useful tool to dimension and predict various performances of networks with TCP and UDP flows, providing information such as mean flow bandwidths, link utilizations or queue sizes. While the literature on flow-level network models is extensive, ther...

Evaluation of Intelligent Transportation Systems (ITS) at the planning level, as well as various short-term planning projects, require the use of appropriate tools that can capture the dynamic and stochastic interactions between demand and supply. The objective of this thesis is to develop a methodological framework for such applications and implement it in the context of an existing dynamic tr...
