A Data Allocation Method over Multiple Wireless Broadcast Channels
In this paper, we concentrate on data allocation methods for multiple wireless broadcast channels to reduce the average data access time. Existing works first sorted data by their access probabilities and allocate the partitions of the sorted data to the multiple wireless channels. They employ the Flat broadcast schedule for each channel to cyclically broadcast all the data items allocated to i...
متن کاملBroadcast Data Placement over Multiple Wireless Channels
The advances in computer and communication technologies made possible an ubiquitous computing environment were clients equipped with portable devices can send and receive data anytime and from anyplace. Due to the asymmetry in communication and the scarceness of wireless resources, data broadcast is widely employed as an effective means in delivering data to the mobile clients. For reasons like...
متن کاملIndex and Data Allocation on Multiple Broadcast Channels Considering Data Access Frequencies
In a wireless environment, the bandwidth of the channels and the energy of the portable devices are limited. Data broadcast has become an excellent method for efficient data dissemination. In this paper, the problem for generating a broadcast program of a set of data items with the associated access frequencies on multiple channels is explored. In our approach, we consider allocating index info...
متن کاملOptimal Index and Data Allocation in Multiple Broadcast Channels
The issue of data broadcast has received much attention in mobile computing. A periodic broadcast of frequently requested data can reduce the workload of the up-link channel and facilitate data access for the mobile user. Since the mobile units usually have limited battery capacity, the minimization of the access latency for the broadcast data is an important problem. The indexing and schedulin...
متن کاملEfficient Data Allocation over Multiple Channels at Broadcast Servers
Broadcast is a scalable way of disseminating data because broadcasting an item satisfies all outstanding client requests for it. However, because the transmission medium is shared, individual requests may have high response times. In this paper, we show how to minimize the average response time given multiple broadcast channels by optimally partitioning data among them. We also offer an approxi...
