In this paper, a ZigBee-based wireless sensor network is proposed. It employs star topology. To reduce the power consumption of each sensor node and meanwhile to lengthen its life-span, we use the STOP mode, only a very low power transmitter is used to monitor the channel when the sensor node is NOT waken up and the sensor node is waken up periodically. Furthermore, the security and reliability of...
ZigBee-based wireless sensor network is proposed. It employs star topology. The work mode of wake up on-demand is adopted for the essential part of ZigBee WSN in order to enlarge the capacity of the sensor network and to resolve the problem of energy supply. We use the STOP mode, only a very low power transmitter is used to monitor the channel when the sensor node is NOT waken up and the sensor node...
Work mode of ZigBee WSN substantially reduce the power consumption of sensor nodes and the probability of information collision. Meanwhile, network life span is extended. Because of the cyclic redundancy check and the encryption algorithmpsilas application, the security and reliability of the system are greatly improved.
