he 5th International Workshop on Security & Optimization for Wireless Networks (SOWN 2016) covers comprehensively the common issues about security and optimization in the hot area of wireless networks, which does hinder further development of its applications. In particular, this workshop concentrates on security problems like key management, privacy, cryptographic protocol and optimization problems like energy-efficient protocol, topology control strategy, QoS, etc.

The objective of this workshop is to present state of the art research results in the rapidly growing area of wireless networks, with emphasizes on security and optimization issues. Following the success of SOWN-11 (held in Beijing, China, in conjunction with MSN-11) and SOWN 2012 (held in Liverpool, UK, in conjunction with IEEE TrustCom-12). SOWN-13(held in Australia, in conjunction with IEEE TrustCom-13). SOWN-15 (held in Liverpool in conjunction with IEEE CIT2015). SOWN-16 provides continuously the participants with opportunities to discuss and explore areas related to the Theory, Development, Applications, Experiences, and Evaluation of wireless networks with fellow students, researchers, and practitioners.
