Conclusion
NGMAST 2008 - Mobile DHT Energy 3
Distributed Hash Tables (DHT) Peer-to-peer systems that enable the storage
and retrieval of <key,value> pairs in a completely distributed and scalable way
Distributed storage systems, file sharing, service discovery, P2P SIP, etc.
DHT nodes communicate with each other via messages (e.g. over UDP datagramms)
There has not been any mobile implementation
NGMAST 2008 - Mobile DHT Energy 4
DHT on mobile phones Mobile Kademlia for Symbian OS
Implements the Kademlia DHT protocol It can connect to the global Mainline
BitTorrent DHT network (usually has more than 1 million concurrent users)
