Abstract: A concept of integrating multi-path data transfer (IMPDT) is introduced to efficiently transfer a large-sized data if multiple heterogeneous networks are available but none of them has sufficient performance for the requested task. IMPDT integrates heterogeneous networks not simply for bandwidth aggregation but also for providing sustainable control information exchange on a stable but low data rate network path, being handled separately from data transmission on different network paths in different ways. In the present paper, the design of a prototype implementation of IMPDT is discussed especially focusing on retransmission, which is evaluated by field experiments using different types of wireless communication systems. Then the design of a prototype implementation of web access system is discussed as an interactive application over multiple challenged networks by integrating the HTTP protocol and the IMPDT scheme, which implies a potentially wide applicability of our proposed scheme.

Keywords: challenged networks; reliable transfer; multipath transfer; heterogeneous networks; wireless networks; data transfer; information exchange; web access.
