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.

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: the neighbor discovery stage, the route establishment stage and the 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 is composed of a sink node D(m,n) and mn-1 ordinary nodes, and provides 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 a neighbor discovery packet, and the node x that receives the neighbor discovery packet replies with a discovery reply packet. After receiving the reply, the source node O(0,0) determines the ID in the reply packet as its own neighbor Nodes store the list of neighbor node...

Abstract

The invention provides an underwater acoustic network penetration routing method, which comprises the following steps that: after nodes in an underwater acoustic network initiate neighbor discovery, a source node starts a timer, calculates to obtain the packet loss rate of a data packet, sets the flag position of a relay data packet of the source node as zero, updates the source node and sends the data packet until a destination node receives the data packet from the source node; and a route is established, successful relaying of data is completed, the connectivity probability of a link is calculated, and a permeation route process is ended and permeated to a destination in a grid, wherein a relay path in a data packet received by a destination node is a finally established route path. Reliable transmission of the route is effectively guaranteed by improving the redundancy of link communication, huge overhead caused by route flooding is greatly reduced by adopting the limiting condition that each data packet is only transmitted once on each link, and the method is simple, effective and easy to operate and implement and has feasibility. Rapid transmission of data packets from a source to a destination is realized, and reliable and timely communication service tasks are provided.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic self-organizing wireless sensor networks, in particular to a percolation 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, has received extensive attention in the past decade, and strategies for developing different potential applications have been proposed. Examples of hydroacoustic network applications include: tactical surveillance, seismic monitoring, aided navigation, pollution monitoring, and many scientific information-based applications. UANs consist of a variable number of sensor nodes to perform collaborative 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...
