Tactile Internet (TI) is, the next frontier of connectivity development wherenot only information but interaction can be exchanged digitally. Much effort in the field of TI has been spent towards developing the necessary technologies needed to transmit interactions over the internet in a naturally perceivedway. However not much has been done on improving the evaluation of these TI technologies, that is, Mean Opinion Score score or Peak Signal to Noise Ratio measures for audio-video applications. Existing measures and measuring methods only give coarse-grained indications of performance and lackthe depth for good comparison. By using Dynamic Time Warping as starting point we propose our new measures Effective Time & Value -Offset that fundamentally changes the way to evaluate performance. We verify our measures by showing it performs significantly better compared to existing work by using data from a new testbed designed to allow testing in stringent network conditions and to be usable for many futureworks.Our contributions will push forward TI development allowing both incremental and novel developments to be tested more easily and with improved verification.

During 9 weeks of investigation multiple solutions for implementing a communication module in a supermarket have been explored. These results led to three options which have been further researched. Bluetooth Low Energy (BLE), 433 MHz and ZigBee have been selected as the best communication protocols
for sensor to gateway communication. Chips for these protocols have been bought and for BLE and 433 MHz libraries have been developed. For the gateway and the communication to the server a Raspberry PI and Mobile Internet have been selected and these have been integrated. During the measurements we came to the conclusion that for the RFM69HCW (433 MHz) and the BLE Nano (BLE) the sleep mode did not work as specified. Resulting in high power consumption and thus worse battery life (sleep mode consumption for RFM69HCW 3.37 mA, BLE Nano 4.38 mA and for XBee 43.2 휇A). The final conclusion of this thesis is that, with the current research, XBee (ZigBee) is
the best communication protocol for communicating within a supermarket. But in further research BLE Nano and RFM69HCW can perform better if the sleep mode is improved to work according to what is specified.
