For developers in telecommunications and graduate students, Wu (computer science and engineering, Florida Atlantic University) compiles 47 essays on new methods and common issues in three connected, yet not often linked, fields: sensor networks, ad hoc wireless networks, and peer-to-peer networks, which combined are called SAP networks. Written by an international and broad group of contributors from universities, research centers, and corporations, the contributions cover theoretic and algorithmic methods used in optimization, computational geometry, graph theory, and combinatorics; protocol security and privacy; scalability design; distributed and localized solutions; data management; operating systems and middleware support; power control systems and design; applications; and performance and simulations.
