یک رویکرد جدید برای شهرهای هوشمند در همگرایی با شبکه های حسگر بی سیم

Internet of things (IoT) for Smart cities has been gradually bringing a sea of technological changes in our day to day life, which in turn helps to make our life more comfortable. Sensing and timely disseminating the information to the base station is the main feature in Internet of Things enabled applications. This function is carried out by the base layer of IoT paradigm and it is consisted of wireless sensor networks (WSNs). In this paper, we propose a WSN-IoT paradigm for real-time applications. The main focus is to find the means of providing information as early as possible to receiver which is prerequisite in smart cities. In this paper, routing is based on the shortest path which is selected using TOPSIS optimization and achieves balance between performance and energy consumption with regard to four criteria’s: 1) Least distance of selected nodes from the base station, 2) Residual Energy, 3) minimum Euclidean distance between mth selected node and 4) next optimum nth node in the transmission range and number of neighboring nodes. Finally, Simulations are conducted in MATLAB in order to demonstrate how the proposed method would work to locate the best node in each cycle and confirm its effectiveness.
