Example text

In our method the volume of feedback is controlled via a time-dependent response probability p(t) which dynamically adapts to variations in the upper-bound of the multicast group size. This adaptive approach ensures that feedback implosion is avoided throughout the session, and at the same time the maximum possible volume of feedbacks, below an implosion threshold, is generated. Furthermore, we describe an alternative filtering method for noise reduction which, unlike previous work, is based on time-dependent Wiener filter.

Hu Background In this section, we give a slightly detailed description of Pastry [11,19], since we propose to support anycast by extending Pastry’s unicast substrate. Pastry is a scalable, fault-tolerant, peer-to-peer substrate. Each Pastry node has a unique, uniformly randomly assigned nodeId (node identifier) in a circular 128-bit identifier space. Given a 128-bit key, Pastry routes the associated message towards the live node whose nodeId is numerically closest to the key. Routing State. For the purpose of routing, nodeIds and keys are thought of as a sequence of digits in base 2b .
