Problems solved by technology

This invention realizes the multi-directional transmission of messages, but its disadvantage is that when messages are forwarded competitively, it will cause broadcast storm problems such as information redundancy, channel contention, and signal collision, which will affect network throughput and other QoS indicators, and easily cause unreliable network

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0049] Such as figure 1 The illustrated embodiment is a broadcast method based on neighbor success broadcast rate in a mobile ad hoc network, the mobile ad hoc network includes several mobile nodes, and all nodes in the network adopt the mode of omnidirectional antenna; The nodes are all on the same plane, and the status of each node is equal; the nodes in the network adopt a distributed structure.

[0050] When the nodes in the network are within the communication range of each other, their communication links are bidirectional; the nodes in the network transmit at the same power, and the range covered by the transmitted message is a circle with a radius of R.

[0051] Specifically include the following steps:

[0052] Step 100, source node i sends a broadcast packet. The specific steps are: write the IP address of the current node i, the s...

Abstract

The invention discloses a broadcast method in a mobile ad hoc network based on a neighbor broadcast success rate, and the method dynamically adjusts the forwarding probability of a node according to the real-time change of the neighbor node broadcast success rate, and enables a node with the lower neighbor node broadcast success rate to have less forwarding chance, or else, enables the node with the higher neighbor node broadcast success rate to have more forwarding chance, thereby reducing the transmission of redundant information in the network. The method is smaller in end-to-end time delay, does not need to transmit additional information during the obtaining of the neighbor node information, reduces the competition among channels in the network, reduces the collision probability of packages, inhibits the generation of a broadcast storm, can effectively improve the broadcast arrival rate of the whole network, and improves the reliability of the network.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a broadcast method based on neighbor success broadcast rate in a mobile ad hoc network that can effectively improve packet arrival rate and reduce time delay. Background technique [0002] Mobile ad hoc network is a centerless and multi-hop mobile network composed of a group of devices capable of transmitting and receiving wireless communication. The broadcast communication in the mobile ad hoc network is mainly used in audio and video playback, routing selection and so on. [0003] With the continuous development of wireless communication technology, many broadcast algorithms have been proposed. Among them, the flood broadcast method is the simplest, but it will cause serious broadcast storm problems, which are manifested in information redundancy, channel competition and signal collision. Therefore, how to effectively suppress broadcast storms and re...
