Abstract

A smart city is defined as a platform for using information and communication technologies to improve the quality of urban life while consuming fewer resources at a lower cost. Cloud technology is attractive because it provides infinite storage and computing capacity, flexibility, and benefits from a cost-efficiency model. Since cloud computing deals with many applications that are time-sensitive has burdened the cloud servers to process the services due to high latencies. Therefore, this work proposed fog computing at the access layer to overcome the latency issue. Also, in this work, a Mixed Integer Linear Programming (MILP) model has been developed to optimize number and locations of fog servers to process data from the IoT devices, so that the latency is reduce for smart city application. Twelve Malacca City’s tourist attractions spots have been selected as the candidate locations to install the fog servers. The result shows that by increasing the processing capacity of fog server can reduce the number of utilize fog server, besides minimizing the latency. Also, the results shows that high processing demand from user also increase the number of utilize fog at latency.
