Embodiment Construction
[0010] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0011] In the designed real-time mobile Ad-hoc network protocol, each node has a sending message queue and a receiving message queue. Message queue applications can set the message priority to any value between 0-127, where 127 is the highest priority. Messages with the same priority are placed in the queue according to the first-in-first-out rule. When a node wants to send a message to another node, it pushes the message into the sending queue, and the protocol processes the message popped from the sending queue as needed, and sends it to the destination node through the network. The receiving node pushes the message into the receiving message queue, and pops up the messages in the queue according to the needs of the application. In order to describe the network topology, a network co...

The invention discloses a real-time moving Ad-hoc network achieving method based on a token transmission mechanism. The achieving method includes the following steps that firstly, a priority arbitration stage is carried out, which of all nodes possesses the highest priority message is known through statistics, a token is transmitted in a network and will reach all the nodes, and the token possesses the highest priority message in the network; secondly, an transmission stage is authorized, the shortest path between the last node in the priority arbitration stage and the node possessing the highest priority message is calculated through a link quality matrix, and authorization is sent to the node possessing the highest priority message through the path; thirdly, a message passing stage is carried out, according to the authorization transmission stage, the node possessing the highest priority message receives the authorization, the node is informed of the information that the node possesses the highest priority message, frames in the stage are initialized, and the message is sent to a target node. According to the real-time moving Ad-hoc network achieving method based on the token transmission mechanism, it is ensured that data reach the target node in real time, and therefore the good data transmission real-time capability is achieved.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing a real-time mobile Ad-hoc network based on token transfer mechanism. Background technique [0002] Mobile Ad-hoc network (wireless self-organizing network, referred to as autonomous network) can quickly build a mobile communication network at any time and any place without the support of basic network facilities. Because the Ad-Hoc network protocol has high saturation throughput and low access delay, it is widely used in fields that require QoS guarantee. However, applications that require collaborative control require real-time network data transmission. For example, a cooperative robot team explores a certain area or enters a dangerous area approached by humans, and the data transmission between robots needs to meet real-time performance. However, the current typical Ad-Hoc network protocols mainly focus on issues such as maximum throughput ...
