An Asynchronous Data Transmission Method in Heterogeneous Wireless Networks

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.

Fusionable and fissionable waves of (2+1)-dimensional shallow water wave equation

“…The interaction solution of nonlinear partial differential equations is a topic of general interest in nonlinear systems [1,2]. Among them, shallow water wave equation is one of the hottest issues in recent years [3][4][5][6][7][8][9], such as marine engineering, hydrodynamics, mathematical physics in other fields. Because its exact solution is a special solution existing stably in space, it has very important practical significance for many complex physical phenomena and some nonlinear engineering problems.…”

“…Many authors obtained various forms of solutions to Eq. ( 2) by using the Hriota bilinear method, Darboux transformation method et al [4][5][6][7][8][9]. The Eq.…”
