Sensor/actuator system for internet delays and packet losses

Network delays and packet losses are two critical parameters for the performance of networked control systems (NCS) in non-deterministic packet networks, such as the Internet. To avoid the need of a remote location, the laboratory experiences in teleoperation or telerobotics uses network simulators to reproduce the delays and packet losses. This paper presents an Internet emulation system that performs as a sensor of Internet delays and packet losses and as an actuator that reproduces these parameters into a local data flow. The paper presents some comparative results and makes a performance analysis of the whole system.
