A method to predict the offloading potential for DTN and WIFI hotspots

An enormous amount of cellular data traffic has been produced by mobile users which exceeds the capacity of cellular network and hence weaken the network quality. The solution is to enhance the capacity of cellular networks which however is expensive and inefficient. As DTNs and Wi-Fi hotspots usually focus on maximizing the amount of cellular traffic that can be offloaded. In most cases due to user mobility these networks provide discontinuous and opportunistic network connectivity to the users and the traffic offloading hence results in no negligible data downloading delay.
