With the rapid development of broadband wireless networks and location sensing technologies, Mobile Social Networks (MSNs) pervade many aspects of our daily lives. By incorporating the spatial dimension with social dimension, MSNs foster many interesting and valuable applications and analysis, such as location recommendation service, personal health care, smart cities, location-based marketing, community discovery, and group behaviour analysis. MSN is influencing our societal and cultural norms, and transforming the method we acquire and share information and the way we communicate with others. However, these mobile social systems are characterised by complex network architectures and abundant contextual information, due to the heterogeneous access techniques and massive amount of data generated from social services and social media streams. Moreover, distinguished from general social networking and computing, wireless network characteristics, social factors, contextual information and insights, human behaviour, security and privacy should be taken into account together to understand and improve the MSN systems, and thereby making MSN a multidisciplinary and interdisciplinary challenge. 

MSNCom workshop is organised with this challenge in mind, aiming to address a wide spectrum of research challenges and key issues in MSNs. Of particular interests are cutting-edge research in the fields of wireless communication, network architecture, social computing, mobile social services and applications, social big data analysis, social knowledge mining, security and privacy, and other related areas. 

MSNCom-2017 will continue the success of MSNCom-2015 which was held in Liverpool, UK. The workshop aims to bring the research community and industry practitioners together and foster a cross-disciplinary scientific forum and provide unique opportunities for sharing new results and discussing emerging directions focused around mobile social networking and computing.
