Effective supplying bandwidth policies for wireless cognitive networks: A logistics approach

Abstract

Nowadays, new communication paradigms such as those related to wireless cognitive networks, can take great advantages from advanced inventory management policies by considering radio resources as an extremely perishable commodity with a short-term life time. Starting from this challenging and multidisciplinary research field, the paper proposes to adapt the NewsVendor model, coming from Logistics, to guarantee an effective bandwidth provisioning for cognitive networks also drawing a comparison with a classical adaptive period inventory management policy. Numerical results, validated throughout simulation campaigns, confirm that the NewsVendor model always outperforms the adaptive period inventory management policy by improving both the total profit and the user satisfaction levels.
