Network Resource Trading: Locating the Contract Sweet Spot for the Case of Dynamic and Decentralized Non-broker Spectrum Sharing

Abstract

This paper aims to present a framework for analysing network resource trading between operators. We present the results for the case of orthogonal inter-operator spectrum sharing as a sub-case of the network resource trading between operators. A two-operator, two-cell scenario has been considered. Operators share bandwidth orthogonally using standard LTE technology, detailed in the paper. An operator can post resources to a local market (neighbouring cells) for trading them with other operators. We were interested in identifying the duration of the resource trading contracts for trading, which would provide throughput gains. Simulations show up to 30% increase of user throughput and a more efficient use of spectrum if we do not consider any monetary cost or value in the model. In a separate idealised scenario, throughput gains of up to 80% are reported.
