A Low-Power Proxy to Allow Unattended Jabber Clients to Sleep

Considerable power is consumed by unused computers. Studies show many of these computers have their power management features disabled in order to maintain their network presence and network connections. Past research proposes to use a low power proxy to ´stand in´ for a computer, allowing it to go to sleep and thus save power while still maintaining its network presence. This paper describes a method to proxy for sleeping Jabber clients. By using a low cost power proxy, Jabber clients can maintain their presence in instant message and chat sessions while sleeping when the user is away from the computer. It keeps a record of session activity for the sleeping client and forwards the record of activity to the client when it wakes up.
