The Systems and Networks Lab (SysNet Lab) at the Department of Avionics, Indian Institute of Space Science and Technology, is a research laboratory specializing in networked systems as well as next-generation computer networks. The lab’s key research areas include Mobile Ad-hoc Networks (MANETs), Wireless Mesh Networks (WMNs), Wireless Sensor Networks (WSNs), Delay Tolerant Networks (DTNs), Software Defined Networks (SDNs), Internet of Things (IoT), satellite networking, Satellite Edge Computing (SEC), 5G/6G satellite integration, 5G/6G testbed development, CubeSat development, Space-Based Hosting Service (SBHS), quantum computing, Brain-Computer Interface (BCI), complex networks, and graph signal processing..

5G/6G Satellite Experiments

The 5G testbed is based on the SrSRAN and Open5GS framework and focuses on the development and integration of 5G/6G technologies. Further, simulation testbed enables experimentation with low-latency communications, as well as testing satellite-terrestrial network integration, handover, and edge computing capabilities.

Brain-Computer Interface (BCI) testbed

The BCI testbed creates BCI datasets for various Indian languages, utilizing OpenBCI hardware. These datasets are used for research in multilingual BCI systems and the development of machine learning and deep learning algorithms that recognize and process brain signals for neuromuscular disorders.

Space-Based Hosting Service (SBHS) hardware and software testbed

The SBHS testbeds provide a platform for deploying and testing databases on satellite and high-altitude balloon platforms. This enables researchers to explore novel architectures and communication protocols for space-based hosting services and edge computing services for remote and rural regions of the world.

Wireless Mesh Network testbed

Additionally, the lab has set up the Wireless Mesh Network (WMN) testbed, "IIST MeshNet," covering D2 and D4, to study the behavior of wireless multihop networks. SDN capabilities have been integrated into the mesh routers for granular network control and enhanced performance analysis.

The lab is equipped with a variety of hardware and software tools, including:
