Enhancement energy efficient TDMA wake up MAC protocol by clustering for wireless sensor networks
Javad Mohammadi Nasiri, Mahmood Fathy, Mohsen Soryani · 2009
This paper proposes energy efficient self organization and medium access control (MAC) protocols for wireless sensor networks. The proposed protocol is based on Time Division Multiple Access Wake Up (TDMA-W) principle and is referred to as CBTW. In the proposed protocol a sensor utilizes its assigned slot only when it is sending or receiving information, otherwise its receiver and transmitter are turned off to avoid unnecessary neighbor listening. In order to accelerate receive response, wake-up packets are used to activate a sleeping node.
