Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Such as figure 1 As shown, the present invention divides the entire underwater network structure into small network blocks of 1000m×1000m×1000m. In shallow seas, each network block contains a normal sensor node. sensor node N j ={n 1 ,n 2 ,...n j} are deployed in these small network blocks according to a deployment strategy that can increase network connectivity and network coverage. Multiple marine animals are regarded as one obstacle, such as figure 1Ma in. Sensor nodes that are required to communicate with each other can sense, receive and forward data packets with consistent transmission range and energy consumption. Also, if the sensor node is not working, it is in a dormant state. The specific routing steps are as follows:

[0037] 1) When a sensor node (current node) wants to send a data packet and the current node perceives th...

Abstract

The invention relates to an energy-efficient and obstacle-avoiding underwater wireless sensor network routing method. According to the method, marine animals are prevented from serving as obstacles tointerfere underwater node communication. The residual energy of nodes is considered in a routing decision, data transmission between the two nodes is realized by utilizing multi-hop forwarding, the whole underwater network is divided into network blocks of 1000m * 1000m * 1000m, each network block comprises a sensor node, and a plurality of marine animals are regarded as an obstacle. The sensor nodes requiring mutual communication can sense, receive and forward data packets, and have consistent transmission range and energy consumption. Further, if the sensor node is not operating, the sensornode is in a sleep state.

Description

technical field [0001] The invention relates to the field of underwater wireless sensor networks, in particular to an energy efficient and obstacle avoidance routing method. Background technique [0002] Underwater wireless sensor networks have the characteristics of high delay, high attenuation, and limited channel resources. Compared with terrestrial wireless communication channels, underwater channels are complex and changeable. Due to the established characteristics of underwater sensor networks, the mature mechanisms, protocols, and algorithms of terrestrial wireless sensor networks cannot be directly applied to underwater networks. At present, the research of underwater wireless sensor network protocol has been paid more and more attention by experts and scholars. Among them, nodes need to consume a lot of energy to send information and receive information, and the energy consumption of sending information is many times larger than the energy consumption of receiving ...
