A Critical Analysis of Sensor based IoT Architectures using Fuzzy TOPSIS

Internet of Things (IoT), a buzzword in Information and Communication Technology, offers a number of promising and attractive applications in various fields like automation, monitoring and control, healthcare etc. These applications have equipped the people with convenience, ease of remote monitoring and control, increased productivity and reduced human intervention making the systems more autonomous. The capabilities of IoT architectures are limited by resource constrained sensor networks (limited bandwidth and power). This calls for the need to develop techniques and architectures that are efficient in terms of bandwidth and power. Hybridization (integration of wired and wireless technology) of sensor based IoT networks has been analyzed for different applications. The possible sensor network architectures (wired, wireless and hybrid) for IoT applications have been discussed along with the critical analysis of application specific requirements. Fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Situation) has been used to determine the type of network that offers tailor made solution to a particular application. Also, generalized hybrid architecture has been proposed for IoT applications.
