- Abstract
- This paper proposes a wakeup-on-demand scheme based on the idea that a device should be woken just when it has to receive a packet from a neighboring device. To prove this scheme, this paper proposes a mathematical model based on the busy cycle of M/G/1 queuing systems to obtain a battery lifetime of one-hop cluster-topology shaped W-WSN. Also, we estimate the performance based on a more realistic log-normal shadowing channel model to prove the correctness of the mathematical analysis of the W-WSN with parameters such as the number of devices, the value of the wakeup period and communication distance variations. © 2011 Springer-Verlag.
