Abstract
Real-time transferring of the haptic sense over the Internet is quite a challenging task. This paper outlines the proposed protocols for transferring haptic streams over the Internet. Moreover, it describes the Quality of Service requirements that a network has to fulfill in order to successfully use haptic interfaces with high update rates over the Internet. Extensive simulations and experiments for the performance evaluation of transport protocols for real-time transferring haptic data are carried out. Complements between simulation and real world experiments are discussed. The metrics that are measured for the performance evaluation are delay, jitter, throughput, efficiency, packet loss and one proposed by the authors, packet arrival deviation. The simulation tests reveal which protocols could be used for the transfer of real-time haptic data over the Internet.

Summary
This paper is an extended version of the paper, presented at IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2017 [1]. It presents the existing transport protocols that could be used for transferring haptic streams with high update rates over the Internet. Simulation and emulation tests for transferring haptic streams over the Internet are undertaken. Researchers [3,4,5,6] try to determine the QoS of the network, in order to maximize the Quality of Experience (QoE) of the user [7] in a real-time internet haptic application. The recent network conditions of the Internet might permit online real-time haptic applications to flourish. This paper investigates whether the Internet is capable of transferring real-time the haptic sense. All the above protocols have been proposed for transferring real-time streams of voice and video, but they have not been tested for transferring the haptic sense.
