Cooperative broadcasting method based on neighbor broadcasting coefficient in mobile self-organizing network

Abstract

The invention discloses a cooperative broadcasting method based on a neighbor broadcasting coefficient in a mobile self-organizing network. The cooperative broadcasting method based on a neighbor broadcasting coefficient in a mobile self-organizing network includes the steps: by means of a mode based on a neighbor broadcasting coefficient, starting sending broadcast grouping from a source node; after any one node as a non-source node in the network receives broadcast grouping, according to a forwarding node address list of the broadcast grouping head, deciding whether or not to forward, if requiring forwarding, according to a broadcasting coefficient, selecting the next hop of forwarding nodes, if not enough, making supplement, and then sending broadcast grouping; calculating the broadcasting coefficient according to the successful broadcasting rate and the residual energy of the neighbor nodes; and updating a neighbor information table in real time during the mutual communication process of any two nodes, and broadcasting until all the nodes do not need forwarding broadcast grouping, or exhausting the energy of nodes. The cooperative broadcasting method based on a neighbor broadcasting coefficient in a mobile self-organizing network has the advantages of greatly reducing the number of forwarding nodes, effectively restraining the broadcasting storm, being able to equalize the network energy, prolonging the service life of network, being adapted to the dynamically changed network topology, and providing certain broadcasting reliability at the same time.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and in particular relates to a cooperative broadcast method based on neighbor broadcast coefficients in a mobile ad hoc network. Background technique

[0002] A mobile ad hoc network is a multi-hop, temporary, and rapidly networking autonomous system composed of a group of mobile nodes with wireless communication transceivers, also known as an ad hoc network or a multi-hop routing network. The nodes in the network have both the functions of a host and a router, and the nodes are independent of each other and have no central control. In the mobile ad hoc network, the broadcast technology is mainly studied from the perspective of suppressing broadcast storm, providing reliable broadcast and prolonging the network lifetime.

[0003] At present, most of the broadcast storm suppression schemes are based on probability, which are mainly divided into two categories, one is the fixed prob...
