To see how Bristle works, consider a mobile node X trying to communicate
with a node Y, whose address is unknown to X. To tackle this problem, X
simply sends the message to a known node in the stationary layer. Based on
a DHT, the stationary layer can route the message to an appropriate node Z
who knows the current address of Y.
3.5 Network Architecture with QoS Provisioning
From a telecom operator's point of view, P2P applications are commonly
considered as a threat. Indeed, as the volume of P2P tra c increases (e.g.,
to something near 90% in some peak hours), P2P applications can lead to
significant revenue loss to telecom operators. A further aggravating impact is
that both capital and operating expenses also need to be increased in order
