A compilation of papers, this book covers the domain of computer networks and security, including fast channel assignment in cellular networks, energy efficiency in wireless networks, steganography, etc. Similarly, interesting survey reports covering tuple space based mobile middleware, and peer-to-peer systems have been included. In the domain of machine intelligence, the book includes significant contributions on topics such as spatial data clustering, natural language parsing, grammar induction, machine learning from visual evidence, text summarization, etc. Whilst topics such as gene-gene networking, nucleotide distribution in DNA from the domain of Bio-informatics are reported, alongside the application of genetic algorithms in resource constrained project scheduling problem. Similarly, interesting topics of algorithm design such as s-directed spanning tree, I-tree construction, multi-context in a concept lattice are also part of this volume.
