“…In general, the reliability of data communication is guaranteed at the MAC level, and researchers mainly achieve coexistence transmission by improving the design of the MAC layer. MAC protocol determines the use of wireless channels in heterogeneous wireless networks and is responsible for the allocation and coordination of wireless communication resources for nodes [8]. e MAC protocol can wake up and transmit data only when there is data to be transmitted according to the working status of each node.…”

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.

“…In recent years, experts from various countries have done a lot of in-depth research on tactical data links, such as network protocols, energy consumption, reliability and network architecture, and network protocols are one of the hot spots. As the most basic protocol of tactical data link network, MAC protocol determines the allocation of channels and affects the performance of the whole network, which has become the focus of network protocol research [3]. According to different access policies, MAC protocols can be divided into three categories: competition protocols, scheduling protocols, and hybrid MAC protocols [4].…”

Under the tide of informationization, information warfare has become the development direction of military transformation. As one of the important signs of the development of information warfare, the tactical data chain overcomes the shortcomings of the traditional warfare platforms and wins the opportunity to master the battlefield situation, improve decision-making efficiency, and enhance the cooperative combat capability. The access control protocol determines how the user sites share the channel resources in the tactical data link system, which has an important impact on system performance and has always been a hot issue in tactical data link research. A multi-level priority polling MAC protocol (MPPMP) is proposed for the actual demand of multiuser multi-priority transmission control in tactical data link systems. The protocol can control the arrival rate of user packets at all levels based on the priority weight matrix named P which based on the user's priority level in the tactical data link system. The simulation results show that the MPPMP can meet the multi-priority transmission control requirements of each user in the system and overcomes the problem that the traditional polling MAC protocol has a single control function. In addition, the design and implementation of MPPMP are implemented by FPGA. The feasibility and correctness of the design are verified by the simulation test and statistical analysis.

Aiming at the Sensor-MAC (S-MAC) framework, the paper introduces the technology of controlling and adjusting the Multi-Step power. When the transmitting nodes transmit the data packets to the receiving nodes, the receiving nodes can measure the Received Signal Strength Indication, which are then transmitted back to the transmitting nodes, which is the basis of distinguishing the transmitting power. It was observed that the power of the Received Signal was larger than the threshold set at the receiving terminal. The error rates of receiving the packets can be reduced by the retransmission caused by the loss of the packets, whereas the throughput of the system can be increased. The simulated results show that the range of the throughput and the packets' successful receiving rate, which is included in the power control S-MAC as the different packet collision rate and the bounded packet re-transmission power, were increased by 3%~10% compared with that which is not included in the power control S-MAC in Multi-hops.
