High-Performance Communication Protocols for Asynchronous Duty-Cycling Wireless Networks
Duty cycling is a technique for saving energy in resource-limited wireless networks such as sensor networks. With duty cycling, each node periodically switches between active and sleeping states, for example being active for only 1 to 10 percent of the time. Wireless duty-cycling networks face many challenges such as maintaining high energy efficiency, ...
