Abstract
Using data broadcasting to provide services has attracted much attention for years and many types of location based services (LBSs) data broadcasting have been studied. The skyline query is one of the LBSs and can find the results that meet one of the conditions given in the query. In this paper, we consider the skyline query in wireless broadcast environments and each data object has two kinds of attributes: spatial and non-spatial attributes. Different queries at different locations thus will have different skyline sets. Two indexing structures based on R*-trees will be studied: the original R*-tree and AR*-tree which indexes the data objects mainly using spatial attributes and the non-spatial attribute is augmented to the R*-tree. We then propose effective approaches that allow the clients to execute the skyline query at any location. Last, the proposed broadcasting protocols are evaluated by performing the experiments in terms of the latency, tuning time, and memory usage.
