This paper proposes a method for scheduling and buffer management in differentiated services networks which is based on JoBS algorithm. JoBS differentiates traffic classes base on delay and loss rate. Furthermore, it supports both relative and absolute constraints. Nowadays with the expansion of Internet traffic and its diversified service requests, the focus is on requirement of new traffic us...

In this letter, we consider an intelligent reflecting surface (IRS)-aided mobile edge computing (MEC) system, where IRS is deployed to assist computation offloading from two users access point connected with cloud. For the IRS-aided data transmission, in contrast conventional non-orthogonal multiple-access (NOMA) and time-division (TDMA), propose a new flexible time-sharing NOMA scheme that all...

This paper explores interactions between congestion control mechanisms at the transport layer and scheduling algorithms at the physical layer in the High-Speed Down-link Packet Access extension to WCDMA. Two different approaches to congestion control – TCP SACK and TFRC – are studied. We find that TCP SACK and TFRC in most respects perform the same way. SIR scheduling give a higher system throu...

Given that the co-existence of multimedia applications will be a norm in the future wireless systems, their quality of service (QoS) requirements need to be guaranteed. This has imposed new challenges in the design of packet scheduling algorithms in these systems. To address those challenges, a new packet scheduling algorithm for real time (RT) traffic in downlink third generation partnership p...

This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...
