Abstract

Overview

With the expansion of IoT technologies and the increasing need for heavy data transmission via infotainment, we are exposed to rising levels of Electromagnetic Radiation (EMR) emitted by various digital sources.

Key Findings

  • The analysis focused on multi-hop packet forwarding with cognitive channel allocation to mitigate EMR from near-field sources like mobile phones.
  • Transmission powers and the duration of usage are pivotal in evaluating the risks posed by prolonged EMR exposure.
  • The study introduces theoretical limits on data rates and channel uses to minimize the harmful Specific Absorption Rate (SAR).

Conclusion

The implementation of a groundbreaking algorithm for multi-hop routing and channel selection using cognitive radios in 5G networks was proven to markedly enhance energy efficiency and reduce the harmful SAR, thus minimally affecting near-field heating and overall health.
