Abstract
With the massive deployment and application of intelligent systems such as smart life, smart medical care, and smart transportation, it is becoming more common for heterogeneous wireless networks such as WiFi, Zigbee, and Bluetooth to coexist in the same physical space. To improve the communication efficiency under the coexistence of heterogeneous wireless networks, this paper proposes an asynchronous data transmission method based on CTC technology, which constantly monitors the sleep and wake-up cycles of heterogeneous devices, makes full use of the wake-up cycle of the receiving terminal, and uses asynchronous methods to achieve cross-technology transmission of data packets. We also give a specific implementation scheme and use the program to simulate the transmission effect. The results show that our proposed method effectively reduces data transmission time and balances channel transmission throughput.
Highlights
In recent years, smartphones, smart bracelets/watches, wireless sensor network devices, etc. have shown explosive growth, with the increasing popularity of smart devices using various wireless communication technologies in daily life and in specific occasions [1]
E key to solve the coexistence problem lies in the cooperative communication between the coexistence technologies. e appearance of cross-technology communication makes the establishment of good communication links between heterogeneous wireless network devices and exchanges control information across heterogeneous technologies
Under the premise of in-depth research and consideration of existing communication standards, to improve the communication efficiency under the coexistence of Complexity heterogeneous wireless networks, this paper presents an asynchronous data transfer method named ADT
Summary
Smartphones, smart bracelets/watches, wireless sensor network devices, etc. have shown explosive growth, with the increasing popularity of smart devices using various wireless communication technologies in daily life (homes, offices, shopping malls, etc.) and in specific occasions (hospitals, factories, etc.) [1]. Have shown explosive growth, with the increasing popularity of smart devices using various wireless communication technologies in daily life (homes, offices, shopping malls, etc.) and in specific occasions (hospitals, factories, etc.) [1]. It is becoming more common for heterogeneous wireless networks (such as WiFi, Zigbee, and Bluetooth) to coexist in the same physical space and industry control [2, 3]. In the coexistence environment of wireless networks, low-power Zigbee, Bluetooth, and other communication technologies will obviously receive interference from highpower WiFi signals. In the coexistence environment of wireless networks, low-power Zigbee, Bluetooth, and other communication technologies will obviously receive interference from highpower WiFi signals. ese differences result in the inability to fairly compete and use channels between different wireless communication technologies, resulting in reduced network throughput and increased communication delay
