摘要：In the present scenario wireless sensor network plays a vital role for many applications. But energy consumption is an important constraint in this technology. In general for extending the network life time the activity of the transceiver should be reduced as it consumes more power. In this work an Adaptive staggered sleep protocol (ASLEEP) for efficient power management is proposed in order to match the network demand. This protocol dynamically adjusts the sleep schedules of nodes in time varying conditions, without any prior knowledge of the network topology. This protocol has been extensively studied and it has been observed that the energy consumed by the sensor nodes will be reduced. Under stationary conditions this will increase significantly the network life. The delivery ratio has also been increased with respect to non-adaptive solutions. The results presented here have been carried out with the help of ns -2 simulation.
