/*Thesis context : */Social mobile networks are networks built 
on-the-fly by wirelessly interconnecting users that carry smart-phones, 
PDAs or small laptops. These networks are envisioned to ensure a 
costless /exchange, deliver, or dissemination of data, services or 
applications /among the mobile users, without any need for expensive 
infrastructure access/[10]./ However, i/n this context, the limited 
resources of hand-held devices and their dense distribution prevent the 
use of pure-based flooding techniques, and require the design of more 
efficient data propagation techniques. Moreover/, in social mobile 
networks a complete path connecting a sender and a receiver, or, more 
generally, one source to a set of target users, may never exist at a 
same moment in time. Thus, data must be routed /over time/, exploiting 
the physical movement of nodes and the opportunistic links they 
establish with each other, through a so-called carry-and-forward 
communication paradigm [1,2]. As a consequence, it becomes of the utmost 
importance to be able to accurately predict contacts among mobile users, 
so to be able to correctly delegate contents to those devices that will 
meet the soonest the final users of the data, reducing resource 
utilization and delivery delays. To that end, social relationships 
become the key to an efficient routing in social mobile networks, since 
they have been shown to have a major correlation with the frequency and 
duration of human contacts [2,3,4]. Also, especially appealing is the 
possibility of tailoring network coding for information dissemination in 
social mobile networks. Recently and successfully employed to improve 
routing performances in wireless networks [5,6,7,8,9], network coding 
exploits some of the features of wireless networking (such as spatial 
diversity, broadcast nature of the medium and data redundancy) to 
improve any information dissemination process: by coding information at 
intermediate relays, random linear network coding can improve the 
throughput, reliability and robustness of traditional routing algorithms.

*Thesis work: *This PhD thesis aims at defining novel strategies to 
improve the dissemination of different types of information (e.g., 
contents, services, applications, updates/patches) in social mobile 
networks. Such original strategies will encompass both social-aware 
techniques and network coding-based solutions. The proposed solutions 
should be able to detect and to adapt to connectivity variations in the 
network, as well as to different content distribution paradigms, 
guaranteeing in all cases a reliable, scalable, and robust data 
delivery. The evaluation of the proposed solutions by simulation and/or 
mathematical analyses is expected.

/*Requirements:*/Candidates must have a Master of Science or equivalent 
degree in Computer Science or Electrical Engineering. The ideal 
candidate has a strong background on wireless communication, protocol 
design, scripting, and network performance evaluation via simulation or 
implementation. Knowledge of social networking, complex networks or 
network coding is a plus. Candidates must be fluent in written and 
spoken english.
