The development of mobile virtual network operators, where multiple
wireless technologies (e.g. 3G and 4G) or operators with non-overlapping
bandwidths are pooled and shared is expected to provide enhanced service
with broader coverage, without incurring additional infrastructure cost.
However, their emergence poses an unsolved question on how to harness such
a technology and bandwidth diversity. This paper addresses one of the
simplest questions in this class, namely, the issue of associating each
mobile to one of those bandwidths. Intriguingly, this association issue is
intrinsically distinct from those in traditional networks. We first propose
a generic stochastic geometry model lending itself to analyzing a wide
class of association policies exploiting various information on the network
topology, e.g. received pilot powers and fading values. This model firstly
paves the way for tailoring and designing an optimal association scheme to
maximize any performance metric of interest (such as the probability of
coverage) subject to the information known about the network. In this class
of optimal association, we prove a result that the performance improves as
the information known about the network increases. Secondly, this model is
used to quantify the performance of any arbitrary association policy and
not just the optimal association policy. We propose a simple policy called
the Max-Ratio which is not-parametric, i.e. it dispenses with the
statistical knowledge of base station deployments commonly used in
stochastic geometry models. We also prove that this simple policy is
optimal in a certain limiting regime of the wireless environment. Our
analytical results are combined with simulations to compare these policies
with basic schemes, which provide insights into (i) a practical compromise
between performance gain and cost of estimating information and; (ii) the
selection of association schemes under environments with different
propagation models, i.e. path-loss exponents.
