Research On Data Collection Strategy Of Wireless Sensor Networks Based On Energy Balancing

Wireless sensor network has been widely studied in academic circles because of its low power consumption and certain adaptability.In recent years,the industry has gradually improved the requirements of wireless sensor network,especially for the network energy balance,network life and other performance has more and more stringent requirements.However,the existing data collection strategies still have the problem of energy imbalance which affects the network life,so it is necessary to further improve the energy balance of the network and extend the life.Therefore,it is of great significance to study the data collection strategy of energy balance.For the data collection strategy of clustered wireless sensor network based on energy balance,this article mainly studies from the following two aspects:Firstly,for the wireless sensor network with a single fixed base station,a cluster-head routing strategy based on energy balancing is proposed.The goal of this strategy is to extend the network life.The cluster-head rotation strategy based on the remaining energy and node location is designed,and the prediction model of the number of cluster-head running rounds is established.When the residual energy of a node is higher than the average of the residual energy of the network and the closer to the center of the cluster,it is more likely to be selected as the cluster head.The prediction model of the number of clusters head running continuously makes cluster head rotation more reasonable and avoids the energy waste caused by frequent cluster head rotation in traditional cluster routing.The simulation results show that compared with the traditional cluster routing strategy,the proposed routing strategy based on energy balancing has more surviving rounds of all nodes,higher energy balancing and longer network life under the premise of guaranteeing the data transmission.Secondly,for the wireless sensor network model that uses the cooperation of fixed base station and mobile base station,a routing strategy based on energy balancing is proposed.The strategy includes two parts:the trajectory design of the mobile base station and the design of the corresponding relationship between common nodes and virtual heads.For mobile base station trajectory design,a reasonable number of mobile base station docking points is predicted.Areas with higher node density are easy to be established as docking points to ensure that the trajectory covers more nodes,making them virtual heads,and more virtual heads make the network life extension;for the distribution of the two types of nodes,this method makes the number of common nodes responsible for each virtual head and the transmission distance of each common node closer,and the energy consumption of the same kind of nodes is similar,ensuring the improvement of network energy balance and the extension of life.In summary,the data collection strategy based on energy balancing for wireless sensor network proposed in this paper not only guarantees the data transmission amount,but also improves the energy balance of the network,and also prolongs the survival time of all nodes,which makes a certain progress.
