Method for transmitting real-time data and non-real time data by Ad Hoc web radio station

Abstract

The invention discloses a method for transmitting real-time data and non-real time data by an Ad Hoc web radio station, comprising the following steps of: (1) dividing data time slots provided for users into static time slots, competition time slots and preserve time slots, wherein the static time slots are distributed to various users in the web, are only used by corresponding users and adopt astatic TDMA (Time Division Multiple Address) occupied mode, the competition time slots can be used by various users and adopt a time slot ALOHA occupied mode, and the preserve time slots can be used by various users and adopt an end-to-end control packet handing occupied mode; (2) transmitting real-time data in the static time slots; (3) transmitting competition data during competition; and (4) transmitting preserve data during preservation. By using the method, the real-time data are transmitted at the static time slots and the non-real time data are transmitted at the completion time slots and the preserve time slots; and on the basis of maintaining a static TDMA access protocol to the maximum extent, the method provides a more flexible access means for the users.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for Ad Hoc network stations to transmit real-time data and non-real-time data. Background technique [0002] The currently widely used cellular mobile communication system is centralized and controlled, and the operation of the network is based on pre-set up network facilities. These two characteristics make the cellular mobile communication system unsuitable for some special occasions. For example, rapid deployment and advancement of troops on the battlefield, rescue after an earthquake or flood. The communication in these occasions cannot rely on any pre-established network facilities, and based on robustness considerations, no central control method can be adopted. At this time, a special communication system is required: the operation of this communication system cannot be based on any pre-established network facilities, and it must be able to realize temporar...

Problems solved by technology

For example, the user wishes to occasionally perform non-real-time file transmission while ensuring frequent real-time exchange of situational information between Adhoc nodes, which requires static allocation of some channels and dynamic allocation of the rest of the channels; in this application Although the dynamic TDMA protocol can realize the dynamic allocation of all channels, but in order to realize the dynamic allocation of a small part of the channel, adding a competition stage to compete for all time slot resources, the overhead is too large, and the real-time index is different from that of the static TDMA protocol. The comparison will be reduced, unable to meet the needs of high real-time applications
