Abstract:

In many special network application scenarios of emergency communication, such as disaster rescue and relief after earthquakes, floods, and other emergencies, a low delay and high reliability communication network is required. Improving channel utilization is an effective way to improve the performance of communication services. Since multiple continuous or non-continuous channels can be aggregated to greatly improve channel utilization, multi-channel bonding is a potential solution for future-oriented emergency response in the communication network. Combining the idea of channel bonding, this paper breaks through the traditional idea of channel combination, and proposes a method of multi-channel bonding based on multi-terminal cooperation, which faces the characteristics of the distributed network structure with no centralized device and the volatility of information infrastructure deployed in the emergency communication scenes. Through multi-terminal collaborative channel evaluation, task type-based multi-channel allocation and multi-channel bonding method, the uncertainty of channel state caused by the difference temporal-spatial constraints of each node is reduced, and the transmission quality and channel utilization in distributed networks are improved. The paper innovatively proposes the concept of channel state factor to quantify the state of the channel by the amount of data in the channel, and performs channel evaluation on this basis. A software-defined radio hardware platform with MATLAB software evaluates the correctness of the proposed theory. In addition, a two-node transceiver experimental system proves its feasibility and effectiveness through actual testing and experimental data analysis.
