Enhanced Home-Balanced Load Distribution For UWSNs

In the 21st century,the proportion of Marine economy in the economy of all countries is increasing.The underwater wireless sensor network which have many advantages,including that its ability to collect data in real time and transmit it to the convergence point for processing,and the sensor nodes do not need to store retained data for a long time and so on,Therefore,the Underwater Wireless Sensor Networks have been widely used in many fields,such as disaster early warning,pollutant monitoring,the monitoring and collection of the hydrological data,Marine resources exploration,auxiliary navigation and Marine military etc.So that the Underwater Wireless Sensor Network has become the research focus of various countries.However,underwater sensor networks(UWSNs)have some disadvantages,such as long propagation delay,high mobility,high BER,limited energy and limited bandwidth,among which node mobility and uneven load distribution of sensor nodes will lead to cavities in UWSNs.In order to better cover an area,avoid cavities,reduce energy consumption and improve throughput,An Enhanced Homo-Balanced Load Distribution method for UWSNs which not only saves energy but also can keep nodes active and sensor network high throughput should be proposed in this paper.The main work and innovations of this paper are as follows:1)During network initialization,even corona nodes are set to sleep mode and odd corona nodes are set to active mode;2)Corona nodes are scheduled.When Corona nodes in active mode consume critical energy,dormant Corona nodes switch to active state;3)By scheduling Corona nodes,Minimize the data traffic load on each Corona node to minimize the data traffic load and balance the power consumption in each Corona node.Simulation results showed that the proposed scheme of this thesis can alleviate the problems of limited energy and bandwidth to a certain extent when it was compared with other schemes.
