An on-line fountain code is defined as a fountain code for which an optimal encoding strategy can be found efficiently given any instantaneous decoding state. This property is important for data distribution in practical networks. In this paper we formalize the problem of on-line fountain code construction, and propose new on-line fountain codes that outperform known ones in having factor 3-5 l...

In a transmission line, sag is intentionally provided to relax the tension on wire when placed between two terminals. However, thermal stress and extreme weather conditions can cause increases in line sag, which eventually damage infrastructure. this regard, paper examines number of measurement techniques based physical or optical properties integrated with signal processing communication techn...
