Mobile Ad-Hoc Network Testing

Reliable Performance Testing of Critical Communication Systems using Propsim Channel Emulation MANET Solution

A Mobile Ad-hoc Network (“MANET”) comprises radio nodes that dynamically self-organize into random network topologies. The network configuration does not rely on any fixed infrastructure, so it is well-suited to defense and public-safety applications. Given the nature of these applications, reliable system performance is critical, which means extensive and rigorous testing requirements.

Propsim MANET channel emulation solution from Keysight Technologies offers an accurate and efficient method for evaluating the end-to-end performance of radio systems under real-world radio propagation conditions. Developers of radio equipment can significantly reduce the need for costly field trials by testing the radio link and network performance in a laboratory environment. Easily troubleshoot and resolve performance issues with realistic modeling of operating conditions.

Achieve Efficient, Robust Network Performance with Systematic MANET Testing in Dynamically Changing Environments

Network-centric security operations require seamless communications between command centers, vehicles and dismounted troops to deliver voice and video streams as well as position data. When communicating on the move, users are exposed to potential issues relating to radio coverage gaps, continuously changing network conditions and security threats (e.g. jamming and sniffing).

Today’s MANET systems use Software Defined Radios (“SDRs”) and cognitive radio technologies to manage connectivity and networking. The performance of a MANET greatly depends on how the waveforms and distributed networking algorithms perform in a dynamically changing environment where radios are ultimately deployed.

Radio channel properties such as path loss, delays, power delay profiles, Doppler, interference from adjacent radios and jamming have a critical impact on how the MANET works in the field. A systematic testing approach from link level to radio groups and larger networks assures high- performing, efficient and robust network operation. Use various mobility scenarios and terrain types during testing to achieve a world-class MANET system.

Enhance Advanced Lab-Based Interoperability and Performance Testing of Mobile Ad-Hoc Networks

Propsim MANET channel emulation solution effectively verifies the performance of single radios and multi-radio operation in the network. As a lab-based tool, it offers the ability to accurately and repeatedly emulate propagation and interference conditions experienced by the radios in the field. Early issue detection and resolution offer substantial cost-savings in the development and testing phases.

Evaluate and Verify Radio Devices and Network Level Performance

Test from early development through product verification

Use Propsim MANET channel emulation solution to test and develop the wireless link and network level performance of radio devices and network functional features.

Test key functionality and connectivity

– Distance delay, path loss and multi-path impact for evaluating the radio link performance under different radio channel conditions in the field

– A selection of waveforms and mechanisms for avoiding detection and interception

– Network protocols and algorithms to manage adaptive connectivity and routing of data packets

Keysight’s Propsim Channel Emulators help you exercise precise control over testing procedures and run fully repeatable test cycles for quick issue identification and resolution. The fully-automated test set-up enables continuous execution of regression and quality assurance tests. Incremental product verification throughout the development cycle using realistic field conditions helps reveal underlying issues at an earlier stage. This leads to cost savings and improved product quality.

Assure Interoperability and Operational Robustness for Networked Communications

Verifying the network’s inter-networking capability, security, reliability and quality of service is a huge challenge for agencies responsible for providing radio equipment and networks to the armed forces. Modern IP packet-based radio systems contain functions to support mobility at different layers in the network (such as combat troop radios, tactical data links with airborne and satellite links). Because of the adaptive operation and the complexity of the system, accurate field testing is almost impossible.

Fortunately, almost all types of tests can be reliably executed in a lab environment. With Propsim MANET channel emulation solution, evaluate new radio systems and verify the interoperability with existing systems. Propsim MANET channel emulation solution offers a systematic verification process that significantly minimizes the need for field trials.

Research and develop new technologies

Work with SDR and cognitive radio technologies to improve coverage, spectrum utilization efficiency, network level capacity and security for industrial, commercial as well as defense applications. Propsim Channel Emulators are widely used in R&D labs and for applied research around the world. In addition to supporting MANET testing, Propsim channel emulators are fully compatible with the latest commercial technologies, including WLAN and LTE. This makes Propsim ideal for developing new technologies and solutions for proprietary and professional radio systems.

Complex scenarios are easy to create using Propsim’s comprehensive test scenario creation tools. Accurately control propagation, mobility and antenna technology-related parameters. Propsim is the only radio channel emulator that enables virtual drive testing by using antenna arrays with user-imported radiation patterns in a 3D propagation environment. Significantly reduce research and development cycles by focusing on actual development work using ready-made and industry-proven evaluation methods instead of spending time developing relevant evaluation methods.
