Adaptive estimation transmission method serving for tactical-level communication network

Abstract

The invention discloses an adaptive estimation transmission method serving for a tactical-level communication network. A communication strategy is reasonably regulated by uninterruptedly estimating a current channel state so as to achieve an effect of implementing optimal bandwidth utilization under a principle of reliable transmission. According to the method, in the transmission process, communication equipment is selected under a principle of a maximum bandwidth under a data available condition, and according to the selected equipment, an initial value of each parameter of a reliable transmission protocol is decided. Then, in the transmission process, cases of a data packet size, a channel delay, a packet loss probability and the like in the transmission process are uninterruptedly monitored, and parameters of an optimal data packet size, a concurrent sliding window size, a data packet life cycle and the like in the transmission process are estimated hereby. Finally, an effect of utilizing an effective channel bandwidth to the greatest degree in the premise of guaranteeing not to cause channel jamming and packet loss is achieved.

Description

technical field [0001] The invention belongs to the technical field of tactical-level communication transmission, and in particular relates to an adaptive estimation transmission method serving a tactical-level communication network. Background technique [0002] In modern warfare, the importance of information transmission is self-evident. As an important part of supporting the entire combat command, the tactical-level communication transmission system must ensure that combat orders are accurately, reliably, and quickly transmitted to each combat unit. The development and optimization of transmission technology has important strategic significance to the whole national defense cause. [0003] Information warfare has become one of the most threatening means in today's battlefield. The combat communication network will inevitably be interfered and attacked by the enemy first. To prevent the combat communication network from being cut off, the tactical-level communication net...

Problems solved by technology

For example, the TCP protocol in the Internet has a high pursuit of reliable data transmission and bandwidth utilization. When the channel is high-quality, the efficiency is excellent, but once faced with a channel with a relatively high inherent packet loss rate, such as shortwave and ultrashortwave, etc., Often due to packet loss, the bandwidth utilization rate drops sharply, and there is no good coping mechanism for channel quality fluctuations

In the face of channels with relatively poor channel quality, the transmission efficiency of generally adopted reliable transmission methods is relatively low.
