Multi-Objective Resource Allocation for D2D and Enabled MC-NOMA Networks by Tchebycheff Method

چکیده
This paper considers a resource allocation problem in device-to-device (D2D) communications sharing the same frequency spectrum. In particular, cellular users (CUs) utilize non-orthogonal multiple access (NOMA) while D2D (DUs) adopt orthogonal division (OFDMA). A multi-objective optimization (MOOP) is formulated, which jointly maximizes sum rate of DUs and CUs uplink taking into account maximum transmit power budget minimum data requirement for CUs. MOOP handled by weighted Tchebycheff method, converts it single-objective (SOOP). Then, monotonic approach employed to solve this SOOP optimally. Numerical results unveil an interesting tradeoff between

Multi-Objective Resource Allocation Scheme for D2D Multicast with QoS Guarantees in Cellular Networks
Device-to-device (D2D) multicast communication can greatly improve the spectrum utilization in a content delivery scenario. However, the co-channel interference and power consumption brought by D2D bring new challenges. All the D2D multicast groups expect to achieve a higher system capacity with less extra energy cost. In this paper, we investigate the uplink resource allocation issue when D2D ...
متن کاملA Multi Objective Fibonacci Search Based Algorithm for Resource Allocation in PERT Networks
The problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. We seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. We assume that the work content required by the activities follows an exponential distribution. The decision variables of the model are the allocated resourc...
متن کاملA heuristic method for consumable resource allocation in multi-class dynamic PERT networks
This investigation presents a heuristic method for consumable resource allocation problem in multi-class dynamic Project Evaluation and Review Technique (PERT) networks, where new projects from different classes (types) arrive to system according to independent Poisson processes with different arrival rates. Each activity of any project is operated at a devoted service station located in a n...

in this research, both resource allocation and reactive resource allocation problems in multi-server dynamic pert networks are analytically modeled, where new projects are expected to arrive according to a poisson process, and activity durations are also known as independent random variables with exponential distributions. such system is represented as a queuing network, where multi servers at ...
متن کاملConstrained consumable resource allocation in alternative stochastic networks via multi-objective decision making
Many real projects complete through the realization of one and only one path of various possible network paths. Here, these networks are called alternative stochastic networks (ASNs). It is supposed that the nodes of considered network are probabilistic with exclusive-or receiver and exclusive-or emitter. First, an analytical approach is proposed to simplify the structure of t...
