Scalable Invalidation-Based Processing of Queries in Broadcast Push Delivery
نویسنده
چکیده
Recently, push-based delivery has attracted considerable attention as a means of disseminating information to large client populations in both wired and wireless environments. In this paper, we address the problem of ensuring the consistency and currency of client's read-only transactions in the case of updates. Our approach is based on broadcasting invalidation reports and is scalable, i.e., its performance and associated overhead is independent of the number of clients. Caching is also considered to improve the latency of queries. Preliminary performance results show the relative advantages of the proposed techniques.

Data dissemination in a mobile computing environment typically uses push based data delivery model. Processing queries under this scenario is challenging because we need to organize the broadcast data to efficiently process queries of an average mobile client. In this paper, we adopt the learning technique from [2] in order to learn the patterns of queries of the average mobile user. We then pr...

Hybrid, i.e., push and pull-based, data delivery is likely to become a method of choice for the distribution of information to a large user population in many new mobile and stationary applications. One of the major issues in hybrid data delivery networks is to provide clients with a consistent and current view on the data delivered by the server through a broadband broadcast channel and a set ...
متن کاملScalable Spatial Query Processing for Location-Aware Mobile Services
Location-aware mobile services(LAMSs) are characterized by a large number of objects and a large number of queries. Moreover, with a large candidate data set, answering LAMSs via scanning through the whole data set becomes extremely expensive. In broadcastbased services, any number of clients can monitor the broadcast channel and retrieve the data as it arrives through the broadcast channel. Th...
