Research of Node Energy consumption Based on Dynamic Power Management in Wireless Greenhouse Control System
The resources of wireless sensor nodes are limited,and the power of nodes is supplied with battery whose capacity is very limited,once the energy of battery is run out,the nodes will lose their effect,so there are serious energy constraint in wireless sensor network.In this paper,the specific energy consumption of sensor nodes is studied by experiments,the energy experimental hardware platform is established with the low power consumption SCM MSP430F135 and wireless transceiver chip CC2420,the relationship of energy consumption and communication distance for nodes is discussed,and the energy management strategy of effective wireless greenhouse monitoring system based on dynamic power management is put forward and discussed,the mobile structure is adopted in the convergent nodes.The experiment and simulation results show that the energy consumption of nodes is proportional to the third power of communication distance,the communication distance of sensor nodes can greatly shorten,and energy consumption is saved.
