An improved MAC protocol for WSN
Dongsheng Wu · Journal of Anhui Institute of Architecture & Industry · 2011
To coordinate every nodes to send the information for avoiding collision.As the characteristic such as limited source and dynamic topology in WSN,the paper proposed A Improved MAC protocol,which used the dynamic listening/sleeping periods for assuring system performance and energy saving.The simulation shows that the ES-MAC protocol not only has a best system performance but also saving most energy than S-MAC protocol and T-MAC protocol.
