The development of telehaptic communication protocols has gained widespread focus over the past decade. Several protocols have been proposed for carrying out telehaptic activities over a shared network. However, a comprehensive analysis of the impact of the network crosstraffic on the telehaptic stream, and the feasibility of Quality of Service (QoS) compliance, is lacking in the literature. In this...
We propose a network-based opportunistic improvisation to adaptive sampling for the forward channel telehaptic data stream on a time-varying network. The algorithm explores real-time tuning of the perceptual deadband parameter to minimize network underutilization, and consequently improves the quality of telehaptic communication. We describe in detail the rationale behind the design choices of the...
Telehaptics applications are usually characterized by a strict imposition of a round trip haptic data latency of less than 30 ms. In this paper, we present Haptics over Internet Protocol (HoIP) - a low latency application layer protocol that enables haptic, audio and video data transmission over a network between two remotely connected nodes. The evaluation of the protocol is carried out through a...
Applications such as telesurgery need low latency communication of haptic data between remote nodes. For the stability of the control loop, a typical round trip delay target is 5 ms or lower. In this paper, we specify an application layer protocol - Haptics over Internet Protocol (HoIP) - which is designed to allow such low latency haptic data transmission without sacrificing on the quality of haptic...
