Network Protocol Optimization for IoT Networks with Hybrid Wired and Wireless Access

In recent years, the application fields of Internet of Things protocols related to wired and wireless communication are also expanding and innovating, and they are also suitable for power line carrier and wireless fusion networking scenarios. However, the access mechanism in this scenario has some problems such as large data transmission delay and low access efficiency, so how to achieve fast access response and ensure the reliability of information transmission is also a key challenge. Considering the above problems, this paper proposes a hybrid access mechanism for power line carrier and wireless fusion networking. In the proposed mechanism, according to the characteristics of wired and wireless channels, the corresponding optimal multiple access mechanism is configured, that is, the wireless channel adopts the SPMA protocol, and the wired channel adopts the collision detection carrier monitoring multiple access method (CSMA/CD protocol). On this basis, the hybrid access mechanism is designed. The simulation results show that the proposed hybrid access mechanism can optimize the delay and throughput parameters of power line carrier and wireless fusion network.
