Center node: "tactile internet and its contribution in the development of smart cities"
  Abstract: The Tactile Internet (TI) is an emerging technology next to the Internet of Things (IoT). It is a revolution to develop the smart cities, communities and cultures in the future. This technology will allow the real-time interaction between human and machines as well as machine-to-machine with the 1ms challenge to achieve in round trip latency. The term TI is defined by International Telecommunication Union (ITU) in August 2014. The TI provides fast, reliable, secure and available internet network that is the requirements of the smart cities in 5G. Tactile internet can develop the part of world where the machines are strong and human are weak. It increases the power of machines so that the value of human power will increase automatically. In this framework, we have presented the idea of tactile internet for the next generation smart cities. This research will provide a high-performance reliable framework for the internet of smart devices to communicate with each other in a real-time (1ms round trip) using IEEE 1918.1 standard. The objective of this research is expected to bring a new dimension in the research of the smart cities.
