Abstract

The invention provides a communication method based on an SPMA protocol backoff algorithm. The method comprises the steps of receiving to-be-transmitted data, and obtaining the priority of the to-be-transmitted data, and acquiring a channel load, and executing backoff or data transmission according to a comparison result of a threshold value corresponding to the priority of the to-be-transmitted data and the channel load. In the process of executing the backoff, the backoff time is calculated according to the channel load, the priority of the to-be-transmitted data and the threshold value corresponding to the priority of the to-be-transmitted data, and the backoff is executed according to the backoff time. According to the method, the channel utilization rate is improved, the time delay is reduced, and the requirement for communication performance in the multi-priority service process can be met.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a communication method based on the backoff algorithm of the SPMA protocol. Background technique [0002] The mobile ad hoc network was born in the 1960s. Compared with the traditional cellular mobile communication system, it has the characteristics of flexible networking, no dependence on infrastructure, no central control node, support for multi-hop transmission, and adaptability to dynamic changes in network topology. , suitable for building communication networks in special environments. In recent years, this technology has been used more and more in military communications, emergency rescue, temporary meetings and other fields. Aeronautical ad hoc network is a typical application scenario of mobile ad hoc network. The nodes participating in the networking can be not only aircraft, but also surface ships and satellites. Nodes in the network can be used as comm...
