The 2013 IEEE International Conference on Mobile Services (MS) aims at providing an international forum that is dedicated to explore different aspects of mobile services, from business, management to computing systems, algorithms, and applications and to promote technological innovations in research and development of mobile services, including, but not limited to, wireless networks, sensor networks, mobile computing, mobile enterprise, mobile eCommerce, collaborative computing and social networks. As an integral part of the Federated Conferences in Service Computing, sponsored by IEEE Computer Society since 2003, research papers accepted by IEEE MS 2013 will be presented to a broader audience at the federated conferences in service computing.
