A Survey on Mobile Data Offloading in Heterogeneous Networks

Abstract: An extra ordinary increase in the mobile applications, data traffic is becoming a major issue in the network. With use of smart phones, laptops and tablets gradually increase the mobile data traffic. Now a day various solutions are available to recover this problem. Mobile data offloading and heterogeneous system is used for controling data traffic and improves the performance, user mobility and coverage ratio. Mobile data offloading reduces difficulties on the cellular network and provide the solution with low cost. In this paper, we present a complete survey of Mobile data offloading techniques and extract the offloading functional requirements for today�s mobile network.

Keywords: Mobile data offloading, heterogeneous system, user mobility, coverage ratio, cellular network.
