One of the most significant downsides of wireless compared to wired communication is the significantly higher error rate. This is exacerbated by traditional Internet communication that enforces bit-by-bit correctness of data, dropping packets if even only a single bit is corrupted. Such a behavior is especially wasteful when considering error-tolerant applications, for example, media streaming. For such applications, tolerating errors can be beneficial. Previous solutions to tolerate errors in transmissions suffered from several drawbacks; most importantly, they did not take packet headers into account, instead only focusing on errors in the payload portions of packets. In this work, we present, analyze and evaluate solutions to tolerate errors in both header and payload portions of packets. First, we explain how to implement error tolerance into existing protocols at the examples of IPv4, UDP, and RTP, all while staying fully backwards compatible to the protocol specifications. We then show that a protocol-independent approach can repair errors in protocol headers and identify the connection a packet belongs to without requiring any knowledge about the protocols it works on. Finally, we focus on how to unlock the full potential of error tolerance for 802.11, by discussing the interaction of error tolerance and acknowledgments, and by proposing a novel rate adaptation algorithm suited for error-tolerant, ACK-less traffic.

The works of the Austrian artist Florian Schmidt (*?1980) vary between painting and sculpture. Their ambiguity results from a specific view of painting which is not defined by its being a picture, but by appearing as a material surface, a relief. In a sculptural approach, wood, cardboard, metal scraps, even parts of disassembled works are related to one another in a way that is neither purely painterly nor sculptural. The works quote the idea of monochromy as that endpoint of representation which reduces the painting to its material surface, while? — ?being made of recycled material?–?they also emphasize the analogy between painting and the readymade. Even basic characteristics of the medium like the picture plane or frame are subtly undermined in Schmidt’s works in which the inner and outer form keep blending into one another. 0Exhibition: Kunsthalle Krems, Austria (20.10.2013-16.2.2014).
