Specific Implementation

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.

Irregular Data

Now a days, most of the data is transmitted between two devices using Wireless network. Although this has made it easier to transmit data, it also has its disadvantages. One of its disadvantage being the irregular data transfer due to the presence of congestion in the intermediate nodes. This paper proposes an idea to overcome the said disadvantage by developing a priority based proactive buffer management for the wireless network through the use of buffer which will be maintained at the source. The buffer is used to regulate the transmission rate of the data packets in accordance with the congestion level which is present in the transmission path. For faster transmission, the data packets having high priority are transmitted while the data packets having lower priority are dropped thereby reducing the quantity of data packets being transmitted, hence overcoming the problem of congestion.
