Novel low energy consumption MAC protocol for the wireless sensor networks
Liu Dong-yang · Journal of Xidian University · 2012
Because of the limited power supply of nodes,wireless sensor network energy efficiency research is gaining more and more attention.The energy consumption of the MAC layer is analyzed.Based on the S-MAC protocol and PD-MAC protocol a novel algorithm AP is proposed.In simulations,the proposed protocol is evaluated in comparison with S-MAC and PD-MAC in the aspects of energy efficiency and accuracy of packets sink received.The result shows that collision probability can be reduced reasonably;that energy consumption can be reduced in a better way and that the network longevity can be enhanced efficiently.
