Implementation And Evaluation Of Power Saving Algorithm For Wireless Sensor Networks
Wireless sensor networks (WSNs) are a key technology in information gathering for smart grid, smart home
automation, health care, etc. However, the battery lifetime of a sensor node is always the major concern of WSNs. To
increase the battery lifetime of a sensor node, this paper implements an efficient power saving algorithm and evaluates its
performance. The proposed algorithm significantly reduces the power consumption of a sensor node while preserving the
accuracy of the recovered data trajectory at the sink node. The performance of the algorithm was evaluated by using ZigBee
CC2530 devices and an oscilloscope to measure their power consumption. The measurement results demonstrate that the
power saving performance and data accuracy of the proposed algorithm are outstanding.
