Chord: A Scalable Peer-to-peer Lookup Service for Internet
... Previous work on consistent hashing assumed that nodes were aware of most other nodes in the system, making it impractical to scale to large number of nodes. In contrast, each Chord node needs “routing” information about only a few other nodes. Because the routing table is distributed, a node resolv ...

This system uses a second radio to inform the nodes that an event has occurred and thus force them to power up. In network terms, this can be achieved by flooding (or by just turning the radio on and simply satu ...
