Embodiment Construction

[0023] Taking the McWiLL terminal as an example below, the specific implementation of the present invention will be further described in detail in conjunction with the accompanying drawings. The system and method in this specific embodiment can support a centerless real-time cluster service with a maximum of 8 hops, and users in the cluster service have priority, and the access time of the cluster service at 8 hops is less than 50mS, and the transmission delay is less than 200mS. Meet the needs of real-time trunking voice command and dispatch calls; support up to 8 hops of centerless real-time data transmission, the access time of data services at 8 hops is less than 50mS, the maximum delay of one-way is less than 100mS, and the maximum delay of two-way is less than 200mS; support Real-time transmission of point-to-point audio and video without a center with a maximum of 8 hops, and the transmission delay is less than 200mS at 8 hops.

Abstract

The present invention proposes a terminal ad hoc network access method, including: a sender: sending an access frame detection signal at a random position of an detected idle time slot or a system preset position; Receive signals from other terminals; if the access fails, wait for a random period of time and then re-initiate the access; if the access succeeds, occupy the time slot to send business messages. b Receiver: receive synchronization information and detection signals from other terminals, and generate a local dynamic routing table; receive service messages from other terminals, judge that the target address of the information is this terminal, and then process it locally; if the target address is another terminal, forward it The business message.

Description

technical field [0001] The present invention relates to wireless communication, in particular to a terminal ad hoc network access method. Background technique [0002] Wireless Mesh technology represented by 802.X.X is the current research focus and focus. This type of wireless Mesh technology is developed for Internet wireless access and applications. Its typical applications are mainly in specific urban areas, complex blocks, building Scenes such as inside and outside the group, office area, family room and personal surroundings. In this application environment, each node is often fixed or moves at a low speed, the network topology changes slowly, the business is mainly Internet access, and the voice and other implementation services are also mainly in the form of VoiP. In terms of technical implementation, the physical layer is the same as PMP, and only the routing processing for Mesh is performed on the MAC. [0003] In scenarios such as tactical communication and emer...
