Packet scheduler plays the central role in determining the overall performance of the 3GPP long-term evolution (LTE) based on packet-switching operation. In this paper, a novel minimum transmit power-based (MP) packet-scheduling algorithm is proposed that can achieve power-efficient transmission to the UEs while providing both system throughput gain and fairness improvement. The proposed algori...

In this paper we deal with the problem of assuring acceptable grade of service and at the same time increasing a total network throughput. This is possible by combining two usually separate switch functions: traffic shaping (policing) and packet scheduling. We have selected a simple packet switch structure with single FIFO (first-in-first-out) queue per input port. Input queuing has an advantag...

Next generation wireless mobile networks is a vast area of research and has many design issues like throughput, delay, packet loss, etc. which deals with data transmission and packet scheduling techniques. Based on the above issues, we focus on data packet delivery based on priority and fairness with minimum delay and jitter. In this proposed paper, we are dealing with packet scheduling of mult...

A performance analysis of an optically interconnected packet-scheduling switch network is presented. The scheduling switch uses a branch of feed-forward delays for each input port, interconnected with elementary optical switches to resolve contention. The scheduling switch is guaranteed to be lossless under a certain smoothness property condition. We investigate the packet-loss performance of t...

Future-generation wireless packet networks will support multimedia applications with diverse QoS requirements. Much of the research on scheduling algorithms has been focused on hard QoS provisioning of integrated services. Although these algorithms give hard delay bounds, their stringent requirements sacrifice the potential statistical multiplexing performance and flexibility of the packet-swit...

Multimedia services are carried by data packet in LTE (Long Term Evolution, LTE) system, such as voice, video, and so on. Quality of Service in multimedia services is essential to user experience. In this paper, we present a packet scheduling algorithm to improve the performance of video traffic. By considering the number of packet loss and packet delay in the buffer, the priority of each user ...

A lot of work has been done addressing issues of fair scheduling in wireline packet networks. Most techniques developed have not effectively address the unique constraints post by a wireless packet network. This report reviews [1], a paper which proposes a model for wireless packet network fair scheduling and provides a protocol that attempts to implement such a model.

The main cause of wasted energy consumption in wireless sensor networks is packet collision. The packet scheduling algorithm is therefore introduced to solve this problem. Some packet scheduling algorithms can also influence and delay the data transmitting in the real-time wireless sensor networks. This paper presents the packet scheduling algorithm (PSA) in order to reduce the packet congestio...

In a packet switching system, arriving packets have variable lengths. They are segmented into fixed size cells before being switched. In packet-mode scheduling, cells from a packet should be delivered contiguously. Even though fixed-size cell scheduling has been well studied, packet-mode scheduling has more advantages: it has a lower implementation cost and higher throughput. In this paper, we ...
