The use of emulation as a preservation strategy is often looked upon with skepticism. Although it may be the only way to render digital objects authentically in the future, emulation is thought to be too technically challenging and therefore too expensive and time-consuming. This line of thought has thus far prevented emulation from being developed for preservation purposes. However, the Nation...

Mobile wireless emulation allows the test of real applications and transport protocols over a wired network mimicking the behavior of a mobile wireless network (nodes mobility, radio signal propagation and specific communication protocols). Two-stage IP-level network emulation consists in using a dedicated offline simulation stage to compute an IPlevel emulation scenario, which is played subseq...

In this paper, we present an architecture to emulate multihop wireless networks on StarBED, a wired-network testbed at Hokuriku Research Center of NICT, Japan. The architecture uses a distributed approach, and it can effectively emulate in real time the properties of WLAN contention-based media access mechanism.
