An efficient node scheduling scheme can significantly improve the energy efficiency for sensor layer in Internet of Things. A squared rectangle partition based node scheduling algorithm is discussed, and then its communication model is extended. While maintaining 100%group coverage rate of network and group global connectivity, an improved squared rectangle partition based node scheduling algorithm is proposed by improving the set value for side length of partitioned squared rectangle. Experimental results show that the proposed algorithm effectively reduces system energy consumption and prolongs network lifetime.
