Embodiment Construction

[0036] Embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0037] figure 1 It is a schematic diagram of an example of an area-limited Ad-hoc network (hereinafter referred to as ARANet) according to the present invention, and what is shown in the figure is a scheduling system for data transmission in nodes of the area-limited Ad-hoc network. The area-limited Ad-hoc network is a variation of the existing wireless Ad-hoc network, but it is different from the existing wireless Ad-hoc network. In the ARANet of the present invention, the limitation of the area is realized by some invisible signals. Through this area limitation, even if the nodes in the area and outside the area are within the communication range of each other, no communication between these two nodes can be established. session. In the ARANet network of the present invention, there may be some battery-powered nodes, and as in a normal d-hoc network, the nodes c...

Abstract

The present invention provides a scheduling method for data transmission in nodes of an area-defined Ad-hoc network. The method includes: forming an Ad based on overlapping areas of the coverage of multiple signal generators located within the Ad-hoc network. ‑hoc network restricted area, divide the restricted area into multiple shards, assign a location priority to each shard, and determine the location priority assigned to the shard in advance to be located within the shard. The location priority of the node; calculate the data transmission priority of each node based on the obtained location priority of the node and the predetermined priority indicator, and based on the calculated data transmission priority of the node, between nodes transfer data.

Description

technical field [0001] The invention relates to a data scheduling method in an area-restricted Ad-hoc (temporary ad hoc) network (ARANet, Area-Restricted Ad-hoc Network) and a system using the method. Background technique [0002] Ad-Hoc network is a multi-hop, centerless, self-organizing wireless network, also known as multi-hop network (Multi-hop Network), infrastructureless network (Infrastructureless Network) or self-organizing network (Self-or- ganizing Network). The entire network has no fixed infrastructure, each node is mobile, and can dynamically maintain contact with other nodes in any way. In such a network, due to the limited range of terminal wireless coverage, two user terminals that cannot communicate directly can use other nodes to forward packets. Each node or host is also a router, they can complete the function of discovering and maintaining routes to other nodes. In the Ad-Hoc network, the communication range of each host is limited, so the route is ge...
