Network Simulator 3 (ns-3) is a powerful tool for modeling the behavior of computer networks using simulation. We have developed three well known differentiated service packet queuing methods: strict priority queuing, weighted fair queuing, and weighted round robin queuing, in the simulation framework. In this paper, we present the implementation details of the three modules as well as their us...

A common problem in networking research and development is the duplicate effort of writing simulation and implementation code. This duplication can be avoided through the use of fast-prototyping methodologies, which enable reusing simulation code in real prototyping and in production environments. Although this functionality is already available by using ns-3 emulation, there are still limitati...

We discuss a particular non-relativistic limit of NS-NS gravity that can be taken at the level action and equations motion, without imposing any geometric constraints by hand. This relies on fact terms diverge in come from Vielbein Einstein-Hilbert term kinetic Kalb-Ramond two-form field cancel against each other. cancelling divergences is target space analogue similar cancellation takes place ...

In networked multi-robot systems, communication plays a major role defining system’s dynamics and performance. Unfortunately, existing multi-robot simulators do not provide advanced communication models. Therefore, given the intrinsic unreliability of wireless communications, significant differences might be observed between simulation and real-world results. Addressing these issues, we present...

In this paper, we present a novel scheme for the multicast transmission of data over Universal Mobile Telecommunications System (UMTS) networks. Apart from the normal multicast transmission over UMTS, we consider the handling of exceptional cases caused by user mobility scenarios. The proposed scheme is in accordance with the current specifications of the Multimedia Multicast/ Broadcast Service...

In Recent survey VANETs have many possible architectures, algorithms and protocols About traffic safety applications and warning message dissemination which are having very less time to reach as well as for highest number of possible vehicles.so in past we have manyapproaches to disseminate the warning messages upon multi hop wireless networks with lesstime consumption.our proposed technique us...

The turbulent RT instability is investigated in the limit of strong mode-coupling using a variety of high-resolution, multi-mode, three dimensional (3D) numerical simulations (NS). The perturbations are initialized with only short wavelength modes so that the self-similar evolution (i. e. bubble diameter D b µ amplitude h b) occurs solely by the nonlinear coupling (merger) of saturated modes. A...
