Wireless sensor networks can be used to monitor environment in remote, unattended, and hostile environment. Nodes relay on limited power source without recharging. Therefore, one of the most important requirements of wireless sensor networks (WSN) is low power consumption. One way of achieving this is by node scheduling. That is schedule redundant nodes to sleep mode to conserve energy. This paper presents scalable energy efficient position independent (SEEPI) node scheduling technique in WSNs. Our design differs from existing approaches in the way that it does not use position information of the node. Simulation results on NS-2.28 shows that performance is at par with the existing methods.
