Managing difference-based objects with sub-networks in peer-to-peer environments

P2P systems are currently being used all over the world. However, existing P2P technology is not able to modify shared objects efficiently. Naive approaches to support modification result in large amounts of traffic and load concentrations. In our study, this issue is being addressed by representing shared objects by their differences. These are stored in a sub-network that is generated for each object. The object is accessed by retrieving and adding the differences stored in the sub-network. A simple simulation demonstrates the effectiveness of this technique in regard to traffic amount and load balancing properties.
