Fog-based energy-efficient routing protocol for wireless sensor networks

By exploiting the benefits of wireless sensor networks (WSNs), the Internet of Things (IoT) has caused many advances in the modern world. Since WSNs have limitations in energy usage, it is critical to save live nodes. Fog computing is a good solution to reduce the limitations of WSNs with its ability to meet the requirements of the IoT applications. Fog computing brings computing and storage resources closer to end users. P-SEP uses fog-based architecture to decrease energy consumption and increase network lifetime. To do so, in this paper, we introduce a new method based on P-SEP which uses FECR and FEAR algorithms in implementation. These algorithms improve the performance of fog-supported WSNs and prolong the lifetime of networks. The performance of the proposed approach is evaluated in comparison with P-SEP. The results of the simulation show that the average amount of energy usage in FECR protocol has been reduced by 9% and by 8% in FEAR. The number of live nodes saved in the network increased by 74% in FECR and 83% in FEAR in comparison with P-SEP protocol.
