Scheduled Channel Polling, a new Media Access Control protocol.
Californian researchers have implemented a new communication protocol for wireless sensor networks which is ten times more energy-efficient than existing protocols. In current sensornets, each individual unit needs to be active at least 30 minutes everyday while this new protocol requires less than two minutes of activity per day. This communication protocol has been developed at the Information Sciences Institute (ISI) of the University of Southern California. Wei Ye was the lead researcher, working with John Heidemann in the ISI Laboratory for Embedded Networked Sensor Experimentation (I-LENSE).
So what did they do?
The activities of the [sensor] units are orchestrated by special operating rules called Media Access Control (MAC) protocols. More than three years of ISI research — supported by the National Science Foundation, Intel and other funders — produced a new protocol, SCP-MAC
