Stitch-n-Sync: Discreetly disclosing topology information using logically centralized controllers

Competitive Mobile Network Operators (MNOs) are typically long-known for their shrewdness to conceal their underlying network topology information. Having said this, in this article, we propose a quasi-distributed topology information sharing framework for network operators based on logically centralized controllers. Through our approach, we present a topology information sharing scheme in which two or more MNOs can cooperatively and more importantly, discreetly reveal their topology information for the sake of utilizing the unused available resources of each other, at times of network failure situations. Our approach has been formulated and developed based on a novel key metric to 'tune' the amount of information sharing. Based on extensive simulations, we then investigate the impacts of network topology information sharing on the network capacity. The overall feasibility is illustrated through significant numerical results.
