Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] refer to figure 1 , a MANET broadcasting method implemented by each node in the MANET in a distributed manner. Each node maintains four types of data structures: a local repeat message table, a local two-step neighbor table, a state indication value Chg_NB of the local two-step neighbor table, and a local broadcast gateway table. Among them, the initialization and reset of the local broadcast gateway table are all implemented by the broadcast gateway selection method; after the local broadcast gateway table is initialized and established, the node initializes Chg_NB to 0; after the local two-step neighbor table is updated, the node sets Chg_NB to 1; After the local broadcast gateway table is reset, the node resets Chg_NB to 0.

[0048] Non-source nodes in the MANET implement said broadcast through the following steps:

[0049] S101: The node receives the broa...

Abstract

The invention discloses a broadcasting method for a mobile ad hoc network, which is implemented by each node in the mobile ad hoc network in a distributed mode, and comprises the following steps that: a, a node judges whether a local two-step neighbor table is updated or not, if so, a step b is performed, otherwise, a step c is performed directly; b, the node resets a local broadcasting gateway table by adopting a broadcasting gateway selection method; and c, the node constructs a broadcast message according to the address of the node and the local broadcasting gateway table, and transmits the broadcast message to all adjacent nodes through a local broadcast. The technical scheme of the invention reduces the network load and the transmission delay of the mobile ad hoc network in the broadcasting process.

Description

technical field [0001] The invention relates to a method for implementing broadcasting, in particular to a broadcasting method for MANET (Mobile Ad Hoc Network, Mobile Ad Hoc Network). Background technique [0002] MANET is a wireless mobile communication system without a center, which is widely used in military, sports and other fields. The most common communication method within the network is broadcasting. Among the MANET broadcast routing protocols, one is to maintain the two-step neighbor table of nodes. In the protocol, each network node maintains the following data structure: [0003] Repeated message table: record the source node address of the broadcast message received by the node, the serial number of the message, and the timestamp and other information, and the node uses these information to judge whether the received message is a repeated message; [0004] Two-step neighbor table: record the information of the neighbor nodes of the node, and the information of ...
