ns-3 is a recently released next generation simulator intended as a replacement of the popular ns-2. It enables a highly rich set of features and is expected to become the first choice of the scientific community soon. ns-3 is in its evolution phase and work at different fronts is still ongoing. With the recent emergence of broadband wireless networks, simulation support for such networks, espe...

Simulation is an essential tool to research in this area and NS-3 is seen as a very promising tool, due to the possibility of simulating complex scenarios. It was recently released to replace the popular NS-2, but it still supports a limited set of technologies. With the recent advances in vehicular networks, position-based routing is seen as an adequate strategy to mitigate the problems brough...

Routing protocols in MANET confront challenges that are not usual in ordinary wired networks. Node movement, intermittent connections, and lack of infrastructure are some of these challenges. Several routing protocols have been proposed to provide better performance delivery and address these challenges. However, an environment is necessary to compare the efficiency of these protocols. In this ...

This paper presents the implementation and performance evaluation of our proposed BGP-GCR+ routing architecture via simulation in ns-2. BGP-GCR+ consists of three components: (1) a two-level hierarchical, non-overlapped, one-node fault-tolerant routing algorithm for large-scale mobile ad-hoc networks (MANETs), (2) an IPv6-based address stateless auto-configuration scheme, and (3) procedures at ...

Time-domain simulation is essential for both analysis and design of complex systems. Unfortunately, high model fidelity leads to large system size and bandwidths, often causing excessive computation and memory saturation. In response we develop an efficient scheme for large-order linear time-invariant systems. First, the A matrix is block diagonalized. Then, subsystems of manageable dimensions ...

This paper presents the implementation of an IPv6 stack within the network simulator NS-3. IPv6 is currently being deployed in the world, and will be the Internet Protocol for at least the next fifty years. On another hand, NS-3 aims at being the reference for simulation of the Internet based communication and thus it is important that NS-3 proposes a framework for IPv6. In this paper, we prese...

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...

A bstract Recent work has shown how on-shell three-point amplitudes in gauge theory and gravity, representing the coupling to massive particles, correspond classical limit curvature spinors of linearised solutions. This connection, made explicit via KMOC formalism split metric signature, turns double copy scattering into Here, we extend this framework universal massless sector supergravity, whi...

In this paper, a new version of the traffic generator script “cbrgen.tcl” to the Network Simulator (NS-2) was developed and applied in many simulation experiments. The main objective of this paper was to study the impacts of varying the transmitted (sent) data rate for the CBR and TCP traffic under varying number of nodes. The performance of MANETs traffic pattern was evaluated with respect to ...
