Recently, the Internet of Things (IoT) has played key roles in every aspect of daily routine tasks. IoT applications suffer from higher latency and limited network bandwidth in the internet core. However, due to bandwidth and resource constraints, the resultant massive data traffic triggers storage overhead, high latency, and network bottleneck problems. Therefore, cloud computing and fog computing are introduced as popular IoT assistance. In fact, using a fog layer with such a highly dynamic environment raises a …
