Multi-Layer Wireless Perception and Recognition Technology Based on Internet of Things

Er-hua Sun, Yu Chen


To study the multi-layered wireless sensation and recognition technology of the Internet of Things, the background and research status at home and abroad were summarized. An IoT system architecture based on a multi-layer multi-reader passive network and a technology for simultaneous simulation of multiple network standards based on OMNeT++ were proposed. The proportion of the time consumption of each communication phase in the entire communication process was analyzed in detail. A variety of strategies for shortening the system delay were proposed. At the same time, multiple network standard protocol stacks were divided and modeled. Dual-layer networks based on IEEE 802.11 and IEEE 802.15.4a were verified as examples. The results showed that the length of the hop sequence and the number of readers were optimized. Therefore, this method is effective.
