A Realistic Beamforming Model for ns-2
2010 Third International Conference on Advances in Mesh Networks, 2010We present an extension to network simulator ns-2 for simulation of smart antennas with maximize gain beamforming. Unlike some of the previous work on this topic, we use a realistic beamforming model with detailed radiation patterns. Our antenna framework can be used to evaluate the characteristics of beamforming under various conditions and can be ...

Modeling the NAJPTC network using NS-2
International Journal of Critical Infrastructure Protection, 2008Abstract Positive Train Control (PTC) refers to microprocessor-based communication technologies that are capable of preventing train collisions, derailments, and injuries to workers operating within the railroad system. In North America, there are 11 competing PTC projects in various stages of refinement.

WiMAX Module for the ns-2 Simulator
2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007This paper presents the design and validation of an WiMAX module based on the IEEE 802.16 standard. The module, which was implemented, includes mechanisms for bandwidth request and allocation, as well as for QoS provision. Moreover, the implementation is standard-compliant.

On TCP Simulation Fidelity in ns-2
Proceedings of the 14th ACM International Symposium on QoS and Security for Wireless and Mobile Networks, 2018The Network Simulator version 2, also known as ns-2, is a widely used platform for network and protocol performance evaluation. Over the years it has benefited from numerous studies in improving its simulation fidelity. Nevertheless, this study discovered that ns-2's TCP simulation accuracy could be impaired substantially in cases where the first-hop ...

Real-Time Network Emulation with ns-2
Eighth IEEE International Symposium on Distributed Simulation and Real-Time Applications, 2004The network simulator ns-2 implements both wireless networks and emulation — a feature that allows to simulate a network environment among real stations. However, the real-time requirements of a network emulation introduce an inaccurate timing behavior of the simulator scheduler.

NS-2 Simulation of VANET for Safety Applications
Proceedings of the 8th International Conference on Computer Modeling and Simulation, 2017NS-2, as an open-source network simulator, is widely used in wireless communication studies and VANET safety applications. In [1], Chen et al. implemented a completely modified architecture about IEEE 802.11 MAC and physical layer modules which depicted the signal transmission and reception process in IEEE 802.11, as well as the method of handling ...

Capability aware AODV algorithm in ns-2 environment
2011 3rd International Conference on Electronics Computer Technology, 2011In the present scenario, mobile communication is being widely used in the areas where infrastructure-based telecommunication systems are unavailable or to deploy one is not cost effective. However, often users suffer due to the fact that mobile devices have very low computational capability and thus are incapable of executing many applications with ...

A module-based wireless node for NS-2
Proceeding from the 2006 workshop on ns-2: the IP network simulator - WNS2 '06, 2006Over the last decade an extraordinary amount of research work at all layers of the network stack has focused on wireless and mobile networks, e.g. wireless local area networks (WLAN), in parallel with their wide acceptance as access technologies. Simulation has been used massively to develop, test and compare new ideas and protocols tailored for such ...

Simulating Sensor Networks in NS-2
2004Abstract : Optimizing sensor networks involves addressing a wide range of issues. These issues stem from limited energy reserves, computation power, communication capabilities, and self-managing sensor nodes. The NS-2 simulation environment is a flexible tool for network engineers to investigate how various protocols perform with different ...
