  • The Pulse Coupling Oscillator (PCO) is a synchronicity model inspired by nature. However, the PCO model has some limitations. The Fast PCO model is proposed in this paper. It addresses the problem of the phase swing actions in the original PCO model. Benefits are the fast synchronicity speed and associated energy saving.

  • In this paper, we make a detailed study about the routing related energy consumption problem in Wireless Sensor Networks. Based on this study, we present the selection criterion of the intermediate nodes so as to make the routing problem energy-efficient. Experimental results are provided with reasonable verification.
