We describe an application of the Legendre transform to communication networks. The Legendre transform applied to max-plus algebra linear systems corresponds to the Fourier transform applied to conventional linear systems. Hence, it is a powerful tool that can be applied to max-plus linear systems and their identification. Linear max-plus algebra has been already used to describe simple data co...

Network simulation tools are frequently used to analyze performance of MANET protocols and applications. They commonly offer only simple radio propagation models that neglect obstacles of a propagation environment. The radio wave propagation model has a strong impact on the results of the simulation run. This work shows different radio propagation models into a simulation tool. The model is bas...

Optical Burst Switching (OBS) is the future of optical internet which provides a promising architecture to efficiently utilize WDM and to fulfill today‘s Internet traffic demands. Since this area is yet to mature there is a darn need to study its various protocols. Network simulator is an important tool for researchers and academicians to simulate and model the actual network at a reduced cost ...

This paper talks about design, development, and application of a new Petri net simulator for modeling and simulation of discrete event system (e.g. information systems). The new tool is called GPenSIM (General purpose Petri Net Simulator). Firstly, this paper presents the reason for developing a new tool, through a brief literature study. Secondly, the design and architectural issues of the too...

We develop an empirical technique to determine the capacity of a mobile ad hoc network. We assume that the network runs on-demand routing and carrier sense-based medium access protocols. The technique, however, is general and should apply to other types of protocols. We develop a tool that determines the network capacity given session-level traffic and node mobility traces. We compare the netwo...

In the last years, diverse network interface designs have been proposed to cope with the link bandwidth increase that is shifting the communication bottleneck towards the nodes in the network. The main point behind some of these network interfaces is to reach an efficient distribution of the communication overheads among the different processing units of the node, thus leaving more host CPU cyc...
