: In wireless sensor networks, to reduce the energy utilization of sensor nodes, this paper presents a Power-Aware Sleep-Scheduled Tree-Based Routing Protocol EEPEG-PA that modifies the chain formation in PEGASIS. Using a distance and sensing range threshold, form a set of paired and unpaired nodes in the network. The paired nodes switch between active and sleep modes to eliminate redundant data and preserve the battery power. To minimize energy utilization as nodes switching between the modes, this scheme considers transitioning to be done based on the node’s residual energy approaching near depleted. To further reduce the energy utilization during transmission, this protocol uses prim’s minimum spanning tree mechanism to transfer the data from the active nodes to the Base Station (BS). Simulation results shows that this proposed mechanism can considerably improve network lifetime in comparison to PEGASIS.
