Energy Cavity Protection Algorithm for Heterogeneous Sensor Networks under Data Drainage
When heterogeneous sensor networks are running,the nodes near the base station of the sensor will lead to energy holes due to more receiving and forwarding times.In order to effectively ensure the safe operation of the net-work,this article presented an energy hole protection algorithm for heterogeneous sensor networks under data drainage.At first,a deployment model of network nodes was constructed to optimize the deployment of sensor network nodes.Moreover,the energy consumption of network nodes was calculated.And then,the energy balance control on the net-work was carried out,so that the number of transmission hops in the cluster of heterogeneous sensor network nodes could be obtained.On this basis,the drainage and allocation for the receiving data were implemented.Finally,the en-ergy consumption of nodes in the sensor network layer was balanced to complete the energy hole protection.Experi-mental results show that the proposed method has high performance and good protection effects as well as lower for-warding and receiving energy consumption.
