PERFORMANCE ANALYSIS OF MOBILE DATA OFFLOADING IN
HETEROGENEOUS NETWORKS
ABSTRACT:
An unprecedented increase in the mobile data traffic volume has been recently
reported due to the extensive use of smartphones, tablets and laptops. This is a major concern
for mobile network operators, who are forced to often operate very close to their capacity
limits. Recently, different solutions have been proposed to overcome this problem. The
deployment of additional infrastructure, the use of more advanced technologies (LTE), or
offloading some traffic through Femtocells and WiFi are some of the solutions. Out of these,
WiFi presents some key advantages such as its already widespread deployment and low cost.
While benefits to operators have already been documented, it is less clear how much and
under what conditions the user gains as well. Additionally, the increasingly heterogeneous
deployment of cellular networks (partial 4G coverage, small cells, etc.) further complicates
the picture regarding both operator- and user-related performance of data offloading. To this
end, in this paper we propose a queueing analytic model that can be used to understand the
performance improvements achievable by WiFibased data offloading, as a function of WiFi
availability and performance, user mobility and traffic load, and the coverage ratio and
respective rates of different cellular technologies available. We validate our theory against
simulations for realistic scenarios and parameters, and provide some initial insights as to the
offloading gains expected in practice.
