Periodic Scheduling in On-Demand Broadcast System
نویسندگان
چکیده
Recent advances in mobile computing have enabled the deployment of broadcast based information systems such as, wireless internet, traffic information systems, etc. These systems are mainly pull-based and their performance very much depends on the broadcast schedule they use. In this paper we focus on on-demand broadcast system. We propose a new ondemand scheduling algorithm that takes scheduling decision at periodic interval, unlike previous algorithms that take decision after broadcasting every data item. This reduces the time client spends monitoring the broadcast channel for data items. We study its behavior with a detailed simulation study and show that our algorithm performs better than the pervious algorithms for on-demand systems.

Integrated Scheduling of Electric Vehicles and Demand Response Programs in a Smart Microgrid
Microgrid (MG) is one of the important blocks in the future smart distribution systems. The scheduling pattern of MGs affects distribution system operation. Also, the optimal scheduling of MGs will be result in reliable and economical operation of distribution system. In this paper, an operational planning model of a MG which considers multiple demand response (DR) programs is proposed. In the ...
متن کاملScheduling time-critical requests for multiple data objects in on-demand broadcast
On-demand broadcast is an effective data dissemination approach in mobile computing environments. Most of the recent studies on on-demand data broadcast assume that clients request only a singledata-object at a time. This assumption may not be practical for the increasingly sophisticated mobile applications. In this paper, we investigate the scheduling problem of time-critical requests for mult...
متن کاملData Scheduling in Multiple Channel/Multiple Receiver Environments for Processing Data Requests with Timing Constraints
In real-time environments, information is disseminated to clients under timing constraints. In this paper, we focus on the real time data scheduling problem in multiple broadcast channels environments, where the clients are equipped with multiple receivers. Each request is associated with a deadline. The clients can either retrieve data items from the broadcast channels or send requests to the ...
متن کاملSimulation studies on scheduling requests for multiple data items in on-demand broadcast environments
Data scheduling for on-demand broadcast has been studied extensively in the past few years. Most work has focused on single-item requests in single-channel architectures. However, this model is not practical for emerging mobile applications. This study investigates data scheduling for multi-item requests in multi-channel on-demand broadcast environments. The performance of several well known sc...
متن کاملScheduling Post-Distribution Cross-Dock under Demand Uncertainty
The system of distribution of goods and services, along with other economic developments around the world, is rapidly evolving. In the world of distribution of goods, the main focus is on making distribution operations more effective. Due to the fact that the cross-dock has the advantage of removing intermediaries and reducing the space required for the warehouse, it is worth considering. Among...
