Players – End user and Provider
 Provider is interested in reduction of his inter-domain
traffic. He must weigh cost/benefit (C, B) of the
mechanism.
 End user benefits from higher QoS (Q), but may suffer
from delay (due to searching for local/prefetched content)
and may need encouraging to participate in WiFi sharing
mechanism (privacy issues?) (D, S).

Chain migration
 More users participate home router sharing, more
likely each user is to benefit from improved QoS.
 Assuming gaussian distribution of users, cumulative
benefit function therefore is expected to reflect
cumulative distribution of normal distribution.
