Cell-Edge SINR Coverage-Aware Positioning of Intelligent Reflecting Surfaces in 6G Internet of Things Networks

Intelligent Reflecting Surface (IRS) is gaining popularity as a game-changing innovation for controlling/adapting wireless connectivity. It is considered to play an important role in achieving an intelligent radio environment following the goal of sixth-generation (6G) networking. IRS may be electronically or intelligently programmed to concentrate, reflect/transmit or dissipate impinging electromagnetic radiation. In this context, it is necessary to analyze the performance of the IRS thoroughly through real-time deployment or computer-aided simulation. The work, therefore, analyzed the positioning of IRS over the coverage region of micro cell to derive optimal placement location to support cell-edge Internet of Things (IoT) devices with a favorable signal-to-interference plus noise ratio (SINR). Moreover, the work derived that the implementation of IRS significantly enhances energy efficiency notably reducing the transmit power of the micro cell base station.
