Allais’ paradox and resource allocation in telecommunication networks

Philippe Ezran, Yoram Haddad, Mérouane Debbah

Telecommunication Systems > 2019 > 70 > 3 > 337-348

The question of resource allocation arises whenever demand exceeds supply. The common approach is to optimize the network efficiency while maintaining some fairness among the users. While resource allocation policies use various definitions for network efficiency and fairness, most of them are based on maximization of a utility function. The mathematical formalism underlying these approaches is the...

Cellular networks are nowadays considered as a major critical infrastructure. Resiliency to failure due to disasters, weather based disruptions or malicious activities is essential. In the case of ring topology, because of delay and availability requirements, a wireless network connected to an aggregation node must sometimes be split into several rings. In this paper, we study the availability optimization...

IEEE Transactions on Wireless Communications > 2017 > 16 > 8 > 4866 - 4879

To reap the benefits of cache-enabled small cell networks, new backaul management mechanisms are needed to prevent the predicted files that are downloaded at the small base stations (SBSs) for caching purposes from jeopardizing the urgent requests that need to be served via the backhaul. Such mechanisms must account for the heterogeneity of the backhaul that will encompass both wireless backhaul links...

This paper investigates a cellular edge caching design under an extremely large number of small base stations (SBSs) and users. In this ultra-dense edge caching network (UDCN), SBS-user distances shrink, and each user can request a cached content from multiple SBSs. Unfortunately, the complexity of existing caching controls' mechanisms increases with the number of SBSs, making them inapphcable for...
