Particular problem in the management of distributed systems is the optimal resource allocation among the subsystems. When several subsystems of the distributed system use or compete for the use of a common resource, the limited capacity of the resource can give rise to constraint system behavior. Respectively, the fast solution of the resource problems strongly influences the application area o...

Nowadays our daily life is not only powered by water, electricity, gas and telephony but by “cloud” as well. Due to the high penetration of cloud-based services or applications into every aspect of our life and the unprecedented increase of digital data, cloud computing becomes the 5th utility that processes and stores these applications and data. Big cloud vendors such as Amazon, Microsoft and...

The paper presents resource allocation optimization in Critical Chain Project Management (CCPM). The cheapest project schedule is searched with respect to time constraints. The algorithm originally developed for the hardware-software co-design of heterogeneous distributed systems is adapted to work with human resources and CCPM method. The results of the optimization showed significant efficien...

The use of relay nodes to improve the performance of BWA networks has been the subject of intense research activities in recent years. Relay enhanced BWA networks are anticipated to support multimedia traffic (i.e., voice, video, and data traffic). In order to guarantee service to network users, efficient resource distribution is imperative. Wireless multihop networks are characterized by two i...

The control and reduction of multiuser interference is a fundamental problem in wireless communications. In order to increase the spectral efficiency and to provide individual quality-of-service (QoS), it is required to jointly optimize the power allocation together with possible receive and transmit strategies. This often leads to complex and difficult-to-handle problem formulations. There are...

The improvement of communication throughput using a cross layer mode of communication is proposed. Due to critical mode of applications of sensor networks, it is required to achieve data at faster rate for high refreshment. As the communicating data’s are sensed or measured data, it is required to have higherthroughput and less interference, to achieve accuracy and optimal resource utilization....

in this paper, we present a genetic algorithm (ga) for optimization of a multi-mode resource constrained time cost trade off (mrctct) problem. the proposed ga, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. beyond earlier studies on time-cost trade-off problem, in mrctct problem, resource requirements of each execution mo...

While heterogeneous cellular networks offer the potential to improve network performance by augmenting coverage and enhancing traffic capacity, resource allocation is extremely complicated due to the heterogeneous and unplanned nature of base station deployments. In this paper, we present SortingHat, a tractable optimization model which leverages the advantages of the different heterogeneous co...

Device-to-device (D2D) communication is a potential technology to improve capacity and energy efficiency of the current wireless communication systems. This work is focused on the application of D2D communication underlaying LTE network for distributed automation (DA) in the smart grid (SG) context. The communication aspects of SG and DA are introduced, and considering the strict reliability an...

Attackers' private information is one of the main issues in defensive resource allocation games in homeland security. The outcome of a defense resource allocation decision critically depends on the accuracy of estimations about the attacker's attributes. However, terrorists' goals may be unknown to the defender, necessitating robust decisions by the defender. This article develops a robust-opti...
