Abstract :
Cellular networks do not have enough capacity to accommodate the exponential growth of mobile data requirement. Data can be delivered between mobile terminals through peer-to-peer WiFi communications (e.g. WiFi direct), but contacts between mobile terminals are frequently disrupted because of the user´s mobility. This paper proposes a Subscribe-and-Send architecture, under which a user subscribes contents on the Content Service Provider (CSP) but does not download the subscribed contents. Some users who have downloaded the contents deliver the contents to the subscribers through WiFi opportunistic peer-to-peer communications. Numerical simulations provide an evaluation of the traffic offloading performance of Subscribe-and-Send. Simulation results show that Subscribe-and-Send architecture can offload 72%~90% cellular network data traffic load.
