Internet Adaptive Deadband for NCS and teleoperation

In this paper, we analyze the relationship between network performance and NCS or teleoperated systems. A new middleware solution called Network Adaptive Deadband is presented, to relate network status and NCS status. Network Adaptive Deadband relates a TCPFriendly flow control algoritm with the deadband filtering solution for NCS data. Based on selected design parameters, an experimental methodology is studied to find the relationship between network consumption and deadband. Application and transport agents for NS2 are developed to simulate a granty crane teleoperated platform and a mass-spring NCS. Results illustrate the succesfull share of public network resources.
