ABSTRACT. Simulation of large-scale networks remains to be a challenge, although various network simulators are in place. In this pa- per, we identify fundamental issues for large-scale network simulation, and propose new techniques that address them. First, we exploit optimistic parallel simulation techniques to.

OMNeT++ networks simulator [3] and it contains the main features needed for simulating large ad-hoc networks of au- tonomous mobile nodes with sensing capabilities. The wireless sensor networks are a particular example of autonomous decentralized systems. Next, the network is asked to solve a problem, which it attempts to do over and over, each time strengthening the connections that lead to success and diminishing those that lead to failure.

However, a more professional way to write the test tcl is to following the way in ns examples. For example, it is better to write traffic patten file and mobility file seperately and then source them in the main test tcl. Those files are generated respectively with cbrgen and setdest tools. Those files are ususally. Ns is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.

S_mbolisms in SLAM II network modelinq. Graphic symbols are used to represent the nodes and the branches of the network. It is recommended that a simulation model be graphically built first and then be coded in the input statements. Some examples of the symbols and. Examples of the Effect of Delay Type Selection. Selecting a delay type affects the regularity of the output as packets pass through the network simulator. The following four graphs are examples of actual delays given to packets in a series of tests performed using the different types of delay settings (Note: in each case. The application field is narrower than general simulation and it is natural that more specific requirements will be placed on network simulations. For example, the network simulations may put more emphasis on the performance or validity of a distributed protocol or algorithm rather than the visual or real-time. Examples.
