Spectrum-aware channel and PHY layer modeling for ns3
نویسندگان
چکیده
The recent interest in tackling the frequency-dependent aspects of communications is pushing a demand for spectrum awareness in simulation tools. Unfortunately, most current network simulators do not deal with this aspect in a satisfactory fashion. In this paper, we present a framework that we developed for the ns3 simulator with the aim of addressing this issue. We discuss the modeling assumptions on which our design is based, and we describe in detail the implementation of the framework as well as of the PHY layer modules that we developed on top of it. Finally, we report some performance evaluation results which show that the proposed solution can achieve a good spectrum modeling accuracy with a modest increase in the computational load.

Channel-aware MAC performance of AMC-ARQ-based wireless systems
This paper proposes a novel framework for the cross-layer design and optimization of wireless networks combining adaptive modulation and coding (AMC) at the physical (PHY) layer with automatic repeat request and channel-aware multiuser scheduling protocols at the data link control (DLC) layer. The proposed framework is based on the use of first-order two-dimensional discrete timeMarkov chains (...
متن کاملJoint Phy-mac Design for Opportunistic Spectrum Access with Multi-channel Sensing
This paper addresses the design of opportunistic spectrum access (OSA) where secondary users are allowed to sense and access multiple channels in the spectrum without causing unacceptable interference to primary users. Integrated in OSA design are a spectrum sensor at the physical (PHY) layer and a sensing and an access strategy at the MAC layer. Within the framework of partially observable Mar...

متن کاملTactical Data Link Channel-PHY Modeling and Simulation in Network Simulator 2
Techniques for modeling and simulating the underlying channel-PHY play an essential role in understanding network protocol and application behavior of tactical data link (TDL). Inappropriate modeling and simulation of channel-PHY make the results incredibility. In this paper a model architecture of channel and physical layer is described in NS-2 (Network Simulator version 2). The five key techn...
متن کاملDistance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
