Abstract

The invention discloses a cooperative broadcasting method based on virtual gravity in a mobile Ad Hoc network. The method based on virtual gravity is used to start sending broadcast packets from source node i; after any node k in the network receives the broadcast packets, The forwarding node address list in the head determines whether to forward or not. If forwarding is required, select up to 4 neighboring nodes as the next hop forwarding nodes according to the positions of all neighboring nodes in the neighbor information table and the virtual gravitational force of the neighboring nodes. When there are less than 4 forwarding nodes, a special address (254.255.255.255) is added, and the addresses of these forwarding nodes are filled in the header of the broadcast packet, and then the broadcast packet is sent. The invention has beneficial effects: the number of forwarding nodes can be greatly reduced, broadcast storms can be effectively restrained, energy consumption can be balanced, and the survival time of the overall network can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a mobile Ad Hoc network based on which can effectively suppress broadcast storms, improve broadcast reliability, balance the energy of nodes in the network, and have a higher arrival rate and lower delay. A collaborative broadcasting method for virtual gravity. Background technique [0002] The mobile Ad Hoc network is an ad hoc network without any central entity. With the support of various pre-designed protocols, it relies on the mutual cooperation between nodes; A wireless communication network that uses multi-hop forwarding technology to compensate for the limited transmission distance of wireless devices, thereby broadening the coverage of the network, providing users with various services, and transmitting various services. It does not need to rely on the existing fixed communication network infrastructure, it can quickly organize and deploy the ...
