Smart world: a better world

With the advancement of technologies, our world is becoming a smart world. In this paper, we share our vision of a smart world, demonstrate different application scenarios and introduce the emerging techniques. We envision that in a smart world, we will become more connected, safe, productive and efficient. To enable a smart world, many advanced techniques such as advanced network, ubiquitous sensing and collaborative computation have been developed. More specifically, they include heterogeneous advanced wireless networks, intelligent transportation, accurate indoor localisation, wireless sensor network, unobtrusive human behaviour sensing and mobile cloud computing. Compared with the previous work, the proposed techniques are faster, more accurate and non-invasive. We firmly believe that by exploiting those techniques, the smart world will be a better world.
