Abstract [en]


Rapidly growing popularity of mobile devices such

as smartphones and digital tablets has changed the way people

obtain information. Cellular and wireless local area networks

provide almost ubiquitous connectivity. However, many scenarios

threaten to leave us disconnected for extended periods of time.

We study how peer-to-peer communication with mobile devices

can be used without network infrastructure. With epidemic

models for opportunistic content spreading we investigate the

performance of such systems and compare them to simulated

results. Real life mobility traces are used as a base to simulate

how information is spread between the devices and two different

types of spreading were studied in more detail. In particular, we

investigate how fast a percentage of the total number of devices

can receive the information. The results are displayed for the best

performing device and indicate that these models does not necessarily

have to agree with what actually happens. Nevertheless, we

argue that the models provide a good mathematical framework

for analyzing systems of this sort and conclude that these models

can be extended to incorporate more general assumptions.
