Example Embodiment

[0123] As shown in Table 1, it is the neighbor information table example format among the present invention, specifically includes:

[0124] ①IP address(node:k): the IP address of the current node k;

[0125] ②The information of the jth neighbor node of k, where j=1, 2,..., n, including:

[0126] IP address(neighbor j:): the IP address of the jth neighbor node of k;

[0127] B kj : the broadcast coefficient of the jth neighbor node of node k;

[0128] t kj : The timeout period of the jth neighbor node of node k.

[0129] IP address(node:k)

[0130] Table 1

[0131] If the timeout time t kj When the timing expires, if the entry of neighbor node j in the neighbor information table of node k has not been refreshed, it is considered that the neighbor node is no longer the neighbor node of the current node k, and the entry of the neighbor node j is deleted from the neighbor information table of the current node k . Timeout time t after each record and refresh kj ...

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...
