Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...

Environmental pollution has caused governments to be concerned about energy saving and the reduction of environmental pollution. Some researchers have presented resource allocation models as multi-objective linear programming (MOLP) in order pay more attention reduction. Energy affects both desirable undesirable outputs. In this paper, we argue for inapplicability existing reducing outputs thro...

Data envelopment analysis (DEA) is a powerful tool for measuring the relative efficiencies of a set of decision making units (DMUs) such as schools and bank branches that transform multiple inputs to multiple outputs. In centralized decision-making systems, management normally imposes common resource constraints such as fixed capital, budgets for operating capital and staff count. In consequenc...

Recently, operators have resorted to femtocell networks to enhance indoor coverage and increase system capacity. Nevertheless, to successfully deploy such solution, efficient resource-allocation algorithms and interference mitigation techniques should be deployed. The new applications delivered by operators require large amounts of network bandwidth. Although, some customers may want to pay mor...

Communication requirements are considered for the cooperative control of wide area search munitions where resource allocation is performed by an iterative network flow. We briefly outline both the single and iterative network flow assignment algorithms and their communication requirements. Then, using the abstracted communication framework recently incorporated into AFRL’s MultiUAV simulation p...

Currently, communication between nanomachines is an important topic for the development of novel devices. To implement a nanocommunication system, diffusion-based molecular communication is considered as a promising bio-inspired approach. Various technical issues about molecular communications, including channel capacity, noise and interference, and modulation and coding, have been studied in t...

Multi-carrier cooperative relay-based wireless communication is of particular interest in future wireless networks. In this paper we present resource allocation algorithm in which sub-carrier pairing is of particular interest along with fairness constraint in multi-user networks. An optimization of sub-carrier pair selection is formulated through capacity maximization problem. Sub-carrier pairi...

In a multi-cell OFDMA system, the total power is minimized by adopting a centralized approach to adjust the subcarriers and power allocation with the interference from other cells into consideration. In this paper, aiming at simplifying the model and reducing the computational complexity, we improved the Penalty-Simulation Annealing (PSA) resource allocation algorithm proposed by [4]. From the ...

Resource Co-allocation is one of the crucial problems affecting the performance of the grid. In addition to this if the system load in each of nodes is nearly equal; it indicates good resource allocation and utilization. It is well known that load balancing is a key factor in developing parallel and distributed applications. Instead of balancing the load in grid by process migration, or by movi...
