Embodiment Construction

[0032] The aforementioned and other technical contents, features and functions of the present invention will be clearly presented in the following detailed description of two preferred embodiments with reference to the drawings.

[0033] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0034] Refer to Figure 1(a)~(d), in the general communication environment, the key unit U key A frame may be delivered to more than one target unit U target , and the key unit U key Must pass through at least one relay unit U hop Carry out communication. Therefore, according to the transmission path recorded in each frame, four transmission modes can be summarized:

[0035] SDSR (Single Destination Single Relay), via a relay unit U hop passed to an object unit U target ;

[0036] MDSR (Multiple Destination Single Relay), via a relay unit U hop passed to multiple target...

Abstract

The invention relates to a frame merging method, which is applicable to a mesh network. The mesh network comprises a plurality of mesh units and a plurality of terminal units, wherein any two units in the mesh units and the terminal units capable of carrying out communication can form a communication pair, and in addition, one of the two units can be used as a key unit for transmitting a plurality of frames to be processed according to the frame merging method. The method comprises the following steps: (A) identifying that the key unit belongs to the mesh unit or the terminal unit; (B) selecting a proper mechanism from a plurality of frame merging mechanisms for the communication pair recorded by each frame to be processed, and taking at least one frame from the frames to be processed forbeing used as a part or the whole of a preferential frame set; and (C) comparing the total size of all frames included in the preferential frame set to the proper frame size for determining whether the key unit sends a gathering frame or not.

Description

technical field [0001] The present invention relates to a frame merging technology, in particular to a frame merging device and method suitable for real-time applications. Background technique [0002] In response to the increasing demand for real-time applications of wireless networks, IEEE (Institute of Electrical and Electronics Engineers) 802.11n proposes to provide a transmission rate up to 600 Mbps (bits per second). However, the transmission content of real-time applications is usually based on small-sized frames (frames), and for the purpose of sending and receiving identification, even if the amount of effective data in the frame is small, it must be transmitted with an additional load (overhead). This not only results in a waste of channel bandwidth, but also limits the degree of improvement in throughput. [0003] For this reason, the known technology proposes three frame combining mechanisms, which are expected to combine multiple frames before sending them out,...
