Many works have tackled on the problem of throughput and fairness optimization in cellular cooperative relaying systems. Considering firstly a two-user relay broadcast channel, we design a scheme based on Superposition Coding (SC) which maximizes the achievable sum-rate under a Proportional Fairness (PF) constraint. Unlike most relaying schemes where users are allocated orthogonally, our scheme...

Packet switching in connection-oriented networks that may have multiple parallel links between pairs of switches is considered. An e cient packet-scheduling algorithm that guarantees a deterministic quality of service to connections with real-time constraints is proposed { this algorithm is a generalization of some recent multiprocessor scheduling algorithms, and o ers realtime performance guar...

The large diversity of applications and requirements posed to current network environments make the resource allocation problem difficult to work out. This paper proposes a dynamic algorithm based on weighted fair queueing (WFQ) to promote fairness (in the Rawlsian sense) and efficiency (in the Paretian sense) in the allocation of bandwidth for multi-application networks. Utility functions are ...

In this paper, we consider a beyond-5G scenario, where two types of users, denoted as scheduled and uncoordinated nodes, coexist on the same set of radio resources for sending data to a base station. Scheduled nodes rely solely on a centralized scheduler within the base station for the assignment of resources, while uncoordinated nodes use an unslotted Carrier Sense Multiple Access (CSMA) proto...

Fair scheduling or Fair Queueing (FQ) algorithms have received much attention in recent years because of their ability to provide a wide range of Quality-ofService (QoS) guarantees to end users. In this paper, we present a new analysis method that can statistically model such fair scheduling algorithms under Poisson arrivals and a general packet length distribution. We coin the new term M/G/FQ ...

changes in credit risk may arise when either the value or the risk of corporate assets changes. changes in the equity value associated with the changes in the asset value and changes in asset risk can be characterized into potentially countervailing direct and indirect effects. the indirect effect of risk on equity value is a function of factors that affect the debt value of including leverage,...

 Background: A fair and just trial, as one of the most fundamental moral demands in the legal system, can have positive consequences in the legal system. The effectiveness of the registration system in society is increasing and it is necessary to conduct appropriate surveys to meet their expectations, especially in terms of paying attention to the substantive rules of fair trial. The rules and ...

The Generalized Processor Sharing (GPS) discipline is proven to have two desirable properties: (a) it can provide an end-to-end bounded-delay service to a session whose tra c is constrained by a leaky bucket; (b) it can ensure fair allocation of bandwidth among all backlogged sessions regardless of whether or not their tra c is constrained. The former property is the basis for supporting guaran...
