Abstract: 


With the availability of more powerful mobile devices  there is significant rise in user generated content (UGC). This is clogging up of current cellular networks. It is  also  clear that  the  traffic  due to UGC is going to continue to grow, and despite the availability of new 4G networks, will  exacerbate  the  problem of congestion in cellular networks. One approach that has been explored by a  number  of  groups  to address  the  problem  of  congestion due to UCG is data off loading, where some of the data is  transmitted  over  other type  of  networks,  for  example WiFi networks. A number of studies have shown that off loading of traffic to WiFi  net- works  as  the potential to significantly reduce the load on cellular networks.  However, there is growing evidence that, in  the  case of off loading to WiFi networks it can only be effectively achieved under special circumstances. This  talk will  review  some  of  the  recent  proposals  and show the requirements for achieving effective data off loading.  Then it  will  present a novel way of distributing user generated by exploiting the time elasticity of UGC and  pre-distributing  content  to  groups  of mobile devices. We will present architecture of the proposed system, which we  refer  to  as Mobitribe,  and  show  viability of the effectiveness of the proposed scheme using some real life data sets.
