Problems solved by technology

However, if the USV only traverses the cluster head nodes, it needs to wait for all nodes to upload data to the cluster head; at the same time, the multi-hop routes with too many nodes in the cluster will consume a lot of energy and increase the probability of node failure, making it difficult to achieve energy balance of nodes
[0006] Second, due to the high importance of some monitoring areas, it is necessary to collect a large amount of data such as images or videos, and the rest of the areas only need to collect middle-level data such as wind force, temperature and salinity. How to deploy sensor network nodes and take into account different collections Problems with scale data to be solved

Abstract

The invention discloses a heterogeneous node cooperative sensing system and method for an offshore self-organizing network, and the method comprises the steps: selecting an optimal sub-cluster head node through employing a fitness equation, and building a self-organizing network model of a three-layer cluster structure; planning a global shortest path of a USV and moving and traversing all clusterhead and sub-cluster head nodes; realizing USV local path planning through a multi-hop relay network formed by the cluster heads and the sub-cluster heads, and planning a USV moving path in real time, so that a heterogeneous node cooperative sensing system oriented to the offshore self-organizing network is established. Through the double-layer collection effect of the cluster heads and the sub-cluster head nodes and the USV global and local combined path planning method, energy consumption balance of the offshore self-organizing network and efficient maintenance and dynamic monitoring of thenetwork can be effectively achieved.
