Monitoring Area Coverage Based on Adjusting Node Spacing in Mixed Underwater Mobile Wireless Sensor Networks

Wireless sensor nodes have the characteristics of small size, light weight, simple structure, and limited energy. They are random during deployment in monitoring area, location is uncertain after deployment. It easy to uneven node distribution, resulting dense some areas sparse areas. In area with nodes, covered repeatedly due distance between which too close. problem covering blind appears far. Aiming at complex structure underwater wireless networks, a coverage algorithm based on adjusting spacing proposed. The calculates reasonable adjacent before moves. increases gradually. simulation results show that can make clustered disperse gradually by reasonably improve effect reduce energy consumption nodes.
