Problems solved by technology

[0007] At present, in the wireless ad hoc network system, the typical broadcasting technology is to learn from the broadcasting method of the point-to-multipoint system, only the source node sends, and there is no relay forwarding. This method can only guarantee one-hop broadcasting, and cannot realize the whole network broadcasting
There is also a broadcast service forwarded to a unicast service, and the source node sends it to other nodes in the network one by one, so as to realize the whole network broadcast, but this method has huge network overhead and low resource utilization

Embodiment 1

[0090] This embodiment provides a multi-hop broadcast scheduling method for ad hoc networks, which is widely applicable to the development of broadcast services in networks using ad hoc network architecture, supports multi-hop broadcast services, and broadcasts across the entire network, and has good quality of service and efficient radio resource utilization, such as figure 1 shown, including the following steps:

[0091] S1. Nodes distributedly monitor their own broadcast service flow, obtain their own broadcast resource requirements, and report to the network scheduling node;

[0092] S2. The scheduling node calculates the resource requirements of the source node and each relay node through the obtained broadcast resource requirements and the maintained network topology, completes resource allocation, and dispatches the calculation results to the entire network;

[0093] S3. Each receiving node sets the last hop node of the route for receiving the broadcast;

[0094] S4, ...

Embodiment 2

[0130] Corresponding to Embodiment 1, this embodiment provides a wireless ad hoc network multi-hop broadcast scheduling device, such as Figure 7 shown, including:

[0131] The node broadcast service flow monitoring and resource request unit 1 is used for distributed monitoring of the node's own broadcast service flow, obtaining its own broadcast resource requirements, and reporting to the network scheduling node;

[0132] The scheduling node processing unit 2 is used for the scheduling node to calculate the resource requirements of the source node and each relay node and complete the resource allocation through the acquired broadcast resource requirements and the maintained network topology, and dispatch the calculation results to the entire network;

[0133] The last hop node setting unit 3 is used for each receiving node to set its own last hop node for receiving broadcasts;

[0134] The broadcast service generating unit 4 is used for sending the broadcast service source n...

Abstract

The invention discloses a wireless ad hoc network multi-hop broadcast scheduling method and device, and relates to the technical field of service control and scheduling in wireless communication, andthe method comprises the steps that a node monitors the condition of a broadcast service flow of the node in a distributed manner, obtains a broadcast resource demand of the node, and reports the broadcast resource demand to a network scheduling node; the scheduling node calculates the resource requirements of the source node and each relay node through the obtained broadcast resource demand and amaintained network topology structure, completes resource allocation, and schedules the calculation result to the whole network; each receiving node sets a routing previous hop node for receiving broadcast; the source node sends the broadcast service; and the broadcast service is received and forwarded by sink nodes. According to the invention, whole-network broadcasting can be realized for the broadcast service, the utilization rate of resources can be effectively improved, repeated receiving can be avoided, and good network service quality is provided.

Description

technical field [0001] The invention relates to the technical field of service control and scheduling in wireless communication, in particular to a multi-hop broadcast scheduling method and device for a wireless ad hoc network. Background technique [0002] Wireless ad hoc network is a distributed wireless group autonomous network, no fixed infrastructure, equal node status, free movement, flexible networking, multi-hop relay, self-healing and other characteristics, in emergency deployment, Public services, military communications and other scenarios are more and more widely used. [0003] In a wireless communication system, broadcasting means that a node sends and other nodes can receive it, that is, one send and multiple receive. Broadcasting technology is widely applicable to application scenarios such as scheduling, command, and control. On the one hand, it can effectively meet the business development needs of one source node and multiple sink nodes; Features, effecti...
