The core concept of Smart Grid (SG) is to enhance the level of intelligent management for power grid by the application of modern information, communication and other advanced technologies. With wide coverage, high reliability and large capacity, the Long-Term-Evolution (LTE) network is widely used in the SG wireless communication. However, SG is different from traditional cellular networks. Many...
Long Term Evolution (LTE) is a broadband wireless technology that promises to high throughput. In order to simultaneously support several mobile users with real time and non-real time applications, the resource management and Quality of Service (QoS) requirements of delay-sensitive traffic should be carefully aware. In this paper, The Delay-Aware with Resource Block Management Scheduling Algorithm...
Wireless Sensor Networks (WSNs) have been widely deployed in monitoring and surveillance areas. With the improvement of sensor nodes' processing capability, multi-media transmission in WSNs has become a new trend. Since multi-media has strict Quality of Service (QoS) requirements, which calls for efficient scheduling algorithm that could guarantee the end-to-end delay and reduce the energy consumption...
This paper proposes a QoE-driven LTE downlink scheduling algorithm which is able to maximise the number of users per cell while maintaining an acceptable QoE for VoIP applications. The QoE-driven scheduling algorithm was implemented in LTE-Sim and its performance was compared to common LTE scheduling algorithms. The main difference between QoE-driven scheduling and existing scheduling mechanisms was...
Service differentiation is known as on the classic and major tasks in IP networks. We propose a novel queuing method which benefits both “Less Impact Better Service” (LIBS) and fuzzy logic paradigms. LIBS leads us to a queuing method called non-congestive queuing, which prioritizes small packets when conditions permit to limit the delay impact of prioritization on congestive applications. In our proposed...
Recently, as 3rd-generation mobile communication services using high-speed data rate system are widely employed, the demand for a variety of real-time data services such as VoIP service are also increased. Unlike typical data packets, VoIP packets have delay bound and low loss rate requirement. In this paper we propose a new scheduling algorithm that schedule two deferent kinds of packets efficiently,...
In this paper we present delay jitter protected-oriented scheduling mechanism for multi-traffic with QoS guaranteed on multi-carrier wireless system. The wireless physical channel quality and the time-delay features requirements of traffics are considered conjointly. When the power is allocated to all sub-carrier according to the water-filling algorithm for maximizing the capacity of the multi-carrier...
Packet loss due to network congestion causes degradation in the quality of networked video transmitted over IP networks. Buffer management and packet scheduling are two key router-based quality of service (QoS) control techniques. Existing buffer management mechanisms mainly focus on preventing network congestion in order to reduce packet loss. However, a low packet loss ratio by itself does not necessarily...
