The recent evolution of IoT being ‘Cognitive Internet of Things’ (CIoT), which is an intelligent automation applicable in a variety of domains. Developing IoT as CIoT can result in as self-reliant without human intervention to function in an intelligent way of decision making to optimize tasks is the sole objective of CIoT aim and purpose. Worldwide urban population is expanding that result in various resources crunch, which hampers sustainable living particularly for urban inhabitants. The urban resources are vital and also critical due to supply and demand mismatch and for sustainable inhabitation, application of IoT/CIoT is relevant as many resources like water, transportation, power, health, housing, education, etc., become scarce for sustainable inhabitation. The paper encompasses by briefing the development and advances of CIoT, specifically its significance in smart cities applications. The CIoT can be trained in taking decisions on par with humans in case of critical situations to find the remedial measures required, which makes the process smart, useful, cognitive for intelligent solution. The properties, characteristics and constraints of CIoT are briefed along with its business applications. Discussion and conclusions are drawn in highlighting the emerging innovation of CIoT, which can become a revolutionary concept in futuristic world of technological novelty in transforming the world as dynamic and smart for the benefit of all the stakeholders.
