Abstract The design principles of pervasive computing software architecturesare widely driven by the need for opportunistic interaction amongdistributed, mobile and heterogeneous entities in the absence ofglobal knowledge and naming conventions. Peer-to-Peer (P2P) frameworkshave evolved, abstracting the access to shared, while distributedinformation. To bridge the architectural gap between P2P applicationsand P2P frameworks we propose patterns as an organizational schemafor P2P based software systems. Our Peer-it hardware platform isused to demonstrate an application in the domain of flexible manufacturingsystems.
