Massive multiple-input and multiple-output (MIMO) and heterogeneous networks (HetNets) have been recognized as potential technologies for the fifth generation mobile networks. On the other hand, the backhaul capacity constraint has become increasingly stringent in HetNets. Consequently, we investigate joint user association and resource allocation to maximize the $\alpha $ -fairness network utility...
The lifetime of machine to machine (M2M) communication networks plays significant impact on system performance and user quality of service (QoS). To increase network lifetime, efficient resource allocation schemes can be applied. In this paper, we study the network lifetime maximization problem of an M2M communication network consisting one base station (BS) and a number of machine type communications...
The pursuit of high data rate and assurance of quality of experience (QoE) for end users represent the main goals of future wireless communication systems. By introducing MOS (Mean Opinion Score) based assessment models for different types of applications, this paper proposed novel QoE-oriented radio resource allocation (RRA) algorithms for multiuser-multiservice femtocell networks. An optimal QoE-oriented...
The weapon target assignment (WTA) problem that arises in defense related applications is to find a proper assignment of weapons to the enemy's targets with the objective of minimizing the total expected survival value of all targets. The WTA problem can be formulated as a nonlinear integer programming problem, and falls into the category of NP-Complete problems. This paper proposes an efficient approximation...
The resource allocation optimization for multicast service in orthogonal frequency division multiple access (OFDMA) systems is an important research topic. It is known that in traditional multicast schemes the rate in each multicast group is severely limited by the user who has the minimum channel gain (MCG) on each subchannel. To counteract this effect, in this paper, we introduce the multiple description...
In this paper we describe an LTE based demonstrator of the Universal Link Layer API (ULLA) and Cognitive Resource Manager (CRM) modules that are developed in ARAGORN project. The demonstrated LTE system comprises one LTE TDD eNode B and one User Equipment (UE). We first introduce ULLA and CRM framework and then demonstrate their suitability to be implemented with the existing LTE equipments. We show...
Balancing Authorities are responsible for managing their system imbalances including deviations caused by the integration of variable generation resources. As wind and solar penetration levels increase, the challenges of managing power variations also increase. Working independently, balancing areas (BAs) with limited regulation and load following capacity and high wind power penetration would face...
Owning to similar business nature, it should be possible to directly migrate successful independent hotel revenue management techniques to the economy hotel in one city. However, one of the salient differences between independent hotel and economy hotel is that one economy hotel usually has many chains in one city. So, not only the chain hotels' revenue but also the global revenue should be considered...
How to balance efficiency and fairness concerning resource allocation in cooperative networks is an interesting research problem. Under the assumption of decode-and-forward (DF) cooperative scheme, this paper studies power allocation problem in user cooperation networks with two users transmitting to a common destination. Specifically, centralized and distributed power allocation schemes are presented...
In demand-oriented IMC process of information age, in the face of rapidly changing market for information resources of sales promotion, how to effectively allocate resources to get the optimal effect of sales promotion, make some infeasible solutions become optimal solutions, according to complementary optimum condition to research inverse optimization of linear programming for enterprise optimal...
The market mechanism based on price is imported into the traditional grid architecture based on hierarchical model, and a grid architecture based on economic model is constructed. Besides the time and cost, grid users also concern about the use value of Grid resources. Accordingly, not only a utility function of grid resource but also a utility function of grid user having the Cobb-Douglas form is...
This paper presents a newly developed resource constrained project scheduling method in stochastic networks by using critical chain concept. The objective of the presented model is defined as minimizing the multiplication of expected project duration and its variance. This paper suggests a competition routine by implementing a policy to maximize the total contribution of selected activities in reducing...
Resource management and optimization among autonomous spatial databases in a grid environment is always a challenge task. In this paper, we introduce a BDI Agent model for cooperating complex spatial query optimization task in a grid environment. Spatial query agents coordinate with spatial database resource agents using FIPA auction protocol for dynamic spatial query execution. The experiment showed...
