  This paper focusses on Service Level Agreement (SLA) based end-to-end Quality
of Service (QoS) maintenance across a wireless optical integrated network. The
wireless network used is Long Term Evolution/Long Term Evolution Advanced
(LTE/LTE-A) mobile network and the optical network is comprised of an Ethernet
Passive Optical Network (EPON). The proposal targets opportunistic allocation
of any bandwidth that is available after meeting the SLA requirements. Such an
opportunistic allocation is particularly beneficial when networking
applications with varying urgency and quality of service requirements are being
operated at the user end. The opportunistic allocation is carried out with the
help of Vickerey-Clarke-Groves (VCG) auction. The proposal allows the users of
the integrated network to decide the payment they want to make in order to
opportunistically avail bandwidth. Learning automata is used for the users to
converge to the optimal payment value based on the network load. The payment
made by the users is later used by the optical network units of the EPON to
prepare the bids for the auction. The proposal has been verified through
extensive simulations.
