Networking Issues in Wireless Sensor Networks
... Research on general schemes of sleep and wake-up focuses on how to set up the communications between two nodes that are normally in sleep mode. These schemes are not tightly coupled with other protocols such as MAC and topology control. Piconet [21] is such an example. In Piconet, each node randomly ...
