Abstract

Quality of Service based packet scheduling is a key-feature of LTE-A mandating selection and transmission of individual user packets based on their priority. HARQ Aware Scheduling, Retransmission Aware Proportional Fair, Chase Combining Based Max C/I Scheduling and Maximum- Largest Weighted First (M-LWDF) are popular Packet Scheduling Algorithms (PSAs) developed to meet QoS requirements. In highly erroneous LTE-A cannel, M-LWDF is considered to be one of best PSA. To validate the performance of M-LWDF for the LTE-A channel, Mean User Throughout, and Fairness performance measures were evaluated for 3 different PSAs designed based on M-LWDF algorithm in this paper. A C++ based simulation results indicate the superiority of the PSA3 algorithm within the threshold of the performance measures against benchmarks. It has shown more efficiency and the performance of RTA traffic was enhanced. Results show that PSA3 is superior to its benchmark PSA2 by 12% in Mean User Throughput and 11% in Fairness. PSA2 performed the worst because it prioritizes new users and it allocated all available RBs to the scheduled user leaving the rest to wait in the buffer. PSA3 maintians good Mean User Throughput and fairnessdue to scheduling each user on its RB which leads to multi-user diversity.

Abstract

Restructuring the power systems and the simultaneous trend to renewable resources has increased the importance of appropriate planning of distribution companies to maximize the potential of distributed resources. Therefore, due to the growing trend of using distributed generations, it is necessary to determine the location and optimal capacity and examine the effects of these units on the power system, especially in the distribution network. Distributed generation sources can be a source of positive impacts, such as improving the technical parameters of the network, including losses, voltage profiles, reliability, and congestion reduction in the power systems, according to the specifications, operating conditions and installation location. In this paper, improvement of the profile and reduction of the losses is used as an object and through appropriate weight coefficients in an object function for the purpose of placement and determining the optimal capacity of the distributed generation sources. In the proposed method the Modified Shuffled Frog Leaping Algorithm (MSFLA) is implemented on an IEEE 33-bus standard network. Also, simulation results are compared with GA and PSO algorithms on the network, which clearly shows the efficiency of the proposed method in the placement and determining the optimal capacity of the distributed generation sources.
