In particular since UMTS operators are searching for new applications which do both: a) exploit the potential of the UMTS technology and b) motivate the user to adopt the new technology. Mobile networks differ from wireline networks mainly by the limited capacity of the radio link, the mobility of the users, and the anticipated content exchanged in these networks. P2P networks, in contrast, are overlays which run on top of a transport network. They consider the transport network only in an abstract way. P2P performance is typically considered on overlay level only. In a mobile environment, the question arises, whether the abstraction can be maintained for underlying mobile transport networks, too, and whether there will be a performance impact. In this paper we investigate the performance of a multiple source download mechanism as used in the popular eDonkey file-sharing network. The performance of the proposed mobile P2P architecture has already been considered for several factors, like the capacity of the mobile access network, the mobility of the users, the application of the cache peer, and the size of typical contents of mobile users such as ring tones, images, and mp3 audio files. However, the performance may be increased by adapting the size of the swapping entities in dependence on these main influence factors. The swapping entities are the smallest units for uploading and downloading user data and are called chunks and blocks, respectively. In this work, we show if and how the swapping entities influence the entire system.
