Power consumption is the main challenges of expanding the network, since the active nodes are more vulnerable to energy consumption. This paper proposes the tasks scheduling and distribution energy management mechanism of roles dormant cells (SRDC) to curb excessive consumption of energy consumed in the performance of duplicates task and unhelpful. Experimental results verify that the proposed of existing protocol LEACH with SRDC approach establishes a low-energy communication structure and led to increase in wireless sensor networks lifetimes.
