Problems solved by technology

Considering the characteristics of large time delay and limited energy of underwater multi-hop network, in order to overcome the problem of poor routing transmission reliability caused by the space-time variation characteristics of underwater acoustic network, and effectively reduce the time delay overhead of the routing process, a water acoustic network is proposed. Acoustic Network Penetration Routing Method

Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0060] The flow chart of this routing method is as follows image 3 As shown, it mainly includes three stages: neighbor discovery stage, route establishment stage and route establishment stage. Specific implementation steps:

[0061] Neighbor Discovery Phase:

[0062] Step 1: The underwater acoustic network is an m×n mesh network, m, n>1, such as figure 1 As shown, the network consists of a sink node D(m,n) and mn-1 ordinary nodes, which implements a reliable routing scheme from the source point O(0,0) to the destination node D(m,n);

[0063] The source node O(0,0) sends the neighbor discovery packet, and the node x that receives the neighbor discovery packet replies with the discovery reply packet. After receiving the reply, the source node O(0,0) determines the ID in the reply packet as its own neighbor The node stores the list of neighbor nodes; ...

Abstract

The invention provides an underwater acoustic network penetration routing method. After each node in the underwater acoustic network initiates neighbor discovery, the source node starts a timer, calculates the packet loss rate of the data packet, and sets the flag position of its own relay data packet as Zero, the source node updates and sends the data packet until the destination node receives the data packet from the source node, the route is established, the successful relay of the data is completed, the connection probability of the link is calculated, the penetration routing process is over, and the destination node is sent to the destination in the grid. Ground penetration, the relay path in the data packet received by the destination node is the final established routing path. The establishment of the invention effectively ensures the reliable transmission of the route by improving the redundancy of the link communication, adopts the restriction that each data packet is only transmitted once on each link, and greatly reduces the huge overhead caused by route flooding , simple and effective, simple to operate and implement, with practicability, realize the rapid transmission of data packets from source to destination, and provide reliable and timely communication service tasks.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic self-organizing wireless sensor networks, in particular to a penetration routing method, which is a routing method for underwater acoustic self-organizing wireless sensor networks. Background technique [0002] Underwater Acoustic Networks (UANs), as a platform for marine research, have received extensive attention in the past decade and have proposed strategies to develop different potential applications. Examples of underwater acoustic network applications include: tactical surveillance, seismic monitoring, aided navigation, pollution monitoring and many applications based on scientific information. UANs consist of a variable number of sensor nodes to perform cooperative monitoring within a given sea area. For USNs, communication coverage must be provided so that the entire monitoring area is covered by sensor nodes, and each sensor node must be able to establish a multi-hop path to...
