Embodiment Construction

[0028] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0029] In the current network environment, low-speed users and high-speed users have the same opportunity to send data packets, which will lead to the problem of uneven distribution of channel occupation time between low-speed users and high-speed users. Based on this, the embodiment of the present invention provides a single A method and device for sending broadcast data packets, so that the processor and all nodes can know the situation of the channel they occupy, and then adjust the number of data packets to be sent according to the situation of the occupied channel to control the occupation time of the channel. The following describes in detail through this embodiment.

[0030] This embodiment p...

Abstract

The invention discloses a method and device for sending unicast data packets. Wherein, the method includes: when the processor determines the unicast data packet to be sent, acquiring the cumulative transmission duration information of the unicast data packet corresponding to each node, and the processor determines the cumulative transmission duration of the current node according to the cumulative transmission duration information. When the information is the minimum value among the cumulative sending duration information of each node in the buffer area, trigger the current node to send the unicast data packet to be sent. The present invention solves the problem in the related art that low-speed users occupy the channel for too long and occupy the channel occupation time of high-speed users, so that the overall throughput of the network decreases, so that the processor can dynamically select each node according to different network states. The opportunity to send data packets can maintain a balance between the channel occupation time of low-speed users and high-speed users, and improve the performance of the processor.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending unicast data packets. Background technique [0002] The main algorithm of the standard Distributed Coordinated Function (DCF) protocol is Narrowband Sense Multiple Access / Collision Detection (Carrier Sense Multiple Access with Collision Avoidance, CSMA / CA for short). figure 1 is a schematic diagram of CSMA / CA backoff according to the DCF protocol of the related technology, such as figure 1 As shown, if the source node wants to send data (DATA), it needs to listen to the channel. The source node can only send data frames if the channel is continuously idle for a specific time interval, such as DCF Inter Frame Space (DIFS for short). If the destination node successfully receives the data frame, it also listens to the channel for a specific time interval, such as Short Inter Frame Space (SIFS for short), and if the channel is idle, the destination ...
