    <event:abstract><![CDATA[We will describe bartering communication model that provides incentives
for collaborations in pervasive environments by supporting P2P bartering
for digital goods such as RingTones, MP3's and podcasts. We examine a set
of bartering strategies and compare their performances.  We examine costs
that a node incurs while looking for the goods in homogeneous and
heterogeneous environment.]]></event:abstract>
