The cellular networks are increasingly facing the challenge of data explosion due high demands of data by users. Several forecasts and analysis indicates that, in the near future the technology cannot cater for the users' data demands. Many attempts to upgrade the technology resulted into inefficient or expensive solution. Cellular data offloading to Wi-Fi is the most promising solution. The two main strategies for cellular data offloading are delay-tolerance and on-the-spot. The on-the-spot offloads less significant percentage of the traffic while the delay strategy achieves higher offloading...
The cellular networks are increasingly facing the challenge of data explosion due high demands of data by users. Several forecasts and analysis indicates that, in the near future the technology cannot cater for the users' data demands. Many attempts to upgrade the technology resulted into inefficient or expensive solution. Cellular data offloading to Wi-Fi is the most promising solution. The two main strategies for cellular data offloading are delay-tolerance and on-the-spot. The on-the-spot offloads less significant percentage of the traffic while the delay strategy achieves higher offloading percentage but with high rate of packet loss and high latency which affect the performance of real-time services. This research proposed an enhancement over the existing delay-algorithm. On receiving the user data request the strategy checks the availability and signal strengths of both the Wi-Fi and cellular and then classified the applications into real-time and non-real-time. The strategy always connects to Wi-Fi network if available.
