Overview of Energy Saving Technologies for Wireless Sensor Networks in the Internet of Things

The energy saving technology of wireless sensor networks in the Internet of Things (IoT) is to extend the life cycle of the network and solve the problem of network energy consumption optimization. In recent years, with the rapid development of IoT technology, wireless sensor network energy saving technology has also received extensive attention and research. Based on the development status of network energy saving technology, this article first describes the wireless sensor network model under the framework of the IoT. Secondly, it focuses on the five common algorithms such as ant colony algorithm, bee colony algorithm, low energy adaptive clustering hierarchy (LEACH) algorithm, fruit fly optimization algorithm, genetic algorithm, etc., and elaborates on each algorithm in detail, and further elaborates various algorithm improvements and strategies. In the end, it summarized the direction that the IoT energy saving technology needs to be improved and developed in the future.
