A comparison of scheduling algorithms in HSDPA
نویسندگان
چکیده
This paper compares the behaviour of Earliest Deadline First (EDF) and Opportunistic-EDF (O-EDF) with that of Round Robin, Proportional Fair Throughput (PFT), and Maximum Carrier to Interference ratio (MaxC/I) . Video, voice and web traffic are transmitted through an HSDPA air interface. The resultant queueing delay and fairness are measured and compared for each scheduler.

A comparison of algorithms for minimizing the sum of earliness and tardiness in hybrid flow-shop scheduling problem with unrelated parallel machines and sequence-dependent setup times
In this paper, the flow-shop scheduling problem with unrelated parallel machines at each stage as well as sequence-dependent setup times under minimization of the sum of earliness and tardiness are studied. The processing times, setup times and due-dates are known in advance. To solve the problem, we introduce a hybrid memetic algorithm as well as a particle swarm optimization algorithm combine...
متن کاملProviding Strict Quality of Service in HSDPA for real time services
Increasing demand for high data-rate real time services has led to the use of shared channels in the forward link for real-time services in 3G wireless networks, such as HSDPA. Strict and differentiated QoS requirements for real-time services, along with time varying channel capacity impose a great deal of challenge on the MAC-hs scheduler. In this paper, we present our policy-based scheduling ...
متن کاملPriority Based Scheduling to Provide Differentiated QoS for Delay Sensitive Services in HSDPA
In wireless cellular networks, normally synchronous dedicated channels are used for real time services due to their delay sensitivity. However the increasing demand for high data-rate multimedia real time services has led to the use of asynchronous time shared channels in the forward link for realtime services in 3G wireless networks, such as HSDPA, EV-DO and EV-DV. Strict and different QoS req...
متن کاملOn the Performance of Multiuser MIMO Systems in WCDMA/HSDPA: Beamforming, Feedback and User Diversity
Several multiple-input multiple-output (MIMO) techniques have been proposed for 3GPP WCDMA/HSDPA systems and several performance evaluation for the comparison purpose are in progress. Most MIMO candidates in HSDPA have been generally designed for pointto-point communication, which means that a single-user throughput is of their major concern. However, multiple users and user scheduling need to ...
متن کاملIssues in Scheduling Multimedia Traffic over the High Speed Downlink Packet Access (HSDPA) link of UMTS
In this paper, some issues in scheduling multimedia traffic over the HSDPA link of UMTS are addressed. Unlike previous contributions, the focus is on the case where packets having different QoS attributes need to be delivered to a specific user as part of a multimedia application packet delivery process. The following packet scheduling algorithms were considered: Max C/I, Proportional Fair (PF)...
