In general, schedulers favor the users with better channel quality because the optimal resource allocation schedules the user with the best channel to exploit multiuser diversity and channel fading, or perhaps the scheduler does not allocate any resources for the mobile host with high error rate because the packets would be dropped anyway.
With the Internet, many of the traditional CSP applications in resource allocation, scheduling and planning pose themselves in open-world settings, where domains and constraints must be discovered from different sources in a network.
This objective is achieved by flexible event-driven reaction on changes in factory environment, resource allocation, scheduling, optimization and controlling in real time.
In the time domain, resource allocation scheduling is performed based on the subframe unit.
In this paper, we propose a cross-layer resource allocation scheduling algorithm, named DSA-RT, for real-time services under frequency-selective fading channel in multiuser OFDM systems.
We justify this requirement by noting that intercell interference can be addressed by proper resource allocation (scheduling) and power control and by arguing that multicell MS would lead to unacceptable complexity in real systems.
For all the above reasons, the design of an efficient and QoS-aware resource allocation scheduling scheme which can address the above issues and improve the network performance is crucial to better satisfy end users' experience based on the application requirements.
In order to evaluate these techniques, we consider three practical task-level scheduling problems: task allocation and scheduling onto multiprocessors, resource allocation and scheduling data transfers between CPU and GPU memories, and scheduling applications with variable task execution times and dependencies onto multiprocessors.
The fourth paper, "Continuous frequency-time resource allocation and scheduling for wireless OFDMA systems with QoS support," presents a joint scheduling and resource allocation scheme for the OFDMA system with continuous subcarrier permutation.
The scheduling method after admission control is reflected in Figure 1. Figure 1 Resource allocation and scheduling steps in LTE.
