In this paper, we develop a distributed power allocation algorithm for maximizing the energy efficiency in the downlink of orthogonal frequency division multiple-access (OFDMA) based multi-cell cellular networks. Each small-cell allocates its available transmit power over the set of assigned sub-carriers to maximize its individual utility (defined as the small-cell's throughput per watt of transmit...
In LTE system, HTTP streaming services sometimes experience video quality deterioration because of the constraint of available wireless resources, which leads to reduce of Quality of Experience (QoE). In this paper, we propose a new scheduling scheme which is QoE-oriented from user's perceptive to improve the performance of HTTP streaming service in a LTE system. First of all, we adopt the jerkiness,...
This study achieves Quality-of-Service (QoS) management in heterogeneous networking using a distributed multi-agent scheme (DMAS) based on the concept of cooperation and the awareness algorithm. The proposed scheme is developed for supporting QoS management in a user-accepted and cost-effective fashion, which consists of a collection of problem-solving agents with three modules: the knowledge source,...
This study develops a novel IEEE 802.21 MIH (Media Independent Handover) mechanism for next generation vehicular multimedia network. An adaptive QoS management mechanism is also proposed. By obtaining received signal strength parameters, the proposed MIH framework can determine the best available network. The adaptive QoS mechanism substantially improves the performance of real-time multimedia applications...
The complex resources and tasks in grid computing environment make it very difficult to validate the methods of resource management and task scheduling. This paper proposes a task scheduling model for grid computing, designs and realizes a target genetic algorithm based on task scheduling method, combining resource management and task scheduling then gives attention to quality of service. The experimental...
