Embodiment Construction

[0016] 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 invention provides a terminal ad hoc network routing method which includes a step a that a terminal maintains a local dynamic routing table which is transferred and updated among terminals at a state of network light load; a step b that a system business adopts a flooding routing method, a local node assisted routing method, or an on-demand routing method or any combination of the three; and a step c that the terminal selects the routing method based on business type and the local dynamic routing situation.

Description

technical field [0001] The present invention relates to wireless communication, in particular to a routing method for terminal ad hoc network. 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...
