“…Then, each channel broadcasts the subset of data items in a 'round robin' manner [30]. Waluyo et al [10] presented a Global Indexing with data placement scheme in multi-channel broadcast environments. The scheme considered index and data allocation over multiple broadcast channels which aimed to minimize query access time, tuning time and power consumption.…”

“…On the other hand, many applications also require the support of a multi-channel architecture due to various reasons such as application scalability, fault tolerance and performance requirements [8,9]. Although several algorithms have been proposed in this architecture [10][11][12][13], they are designed for push-based broadcast systems. This paper makes two main contributions.…”

“…The clients are to obtain the index directory from the channel and use it in subsequent reads. The index enables mobile clients to conserve energy by switching to "doze" mode and back to "active mode" when the data is about to be broadcast [26,27].…”

This paper proposes a new global index structure and processing for location-dependent queries in mobile broadcast environments. The proposed scheme consists of two essential elements for addressing spatial queries in broadcast databases. These two elements are: (i) determine the client's location in relevant to the spatial model adopted by the broadcast scheme, and (ii) obtain the required object, which corresponds to the location of the client as determined by the model. The global index's concept will enhance the efficiency of the model. We explore the effectiveness of the proposed index scheme in single and multi channel environments. Performance comparisons with the earlier work through simulated-experiments have also been carried out and the results found have been promising.Index Terms-location-dependent mobile broadcast query processing, enhanced global indexing scheme, location-based wireless data dissemination.

“…The search continues until an exact match is reached, the current root node is most similar to the query object, or a leaf node is reached, where in this case the leaf node will be the best match. Furthermore, SSeg-tree can be used to enhance the effectiveness of various multimedia indexing applications, such as the systems in Waluyo et al (2005), Yang and Hurson (2005), Rahayu (2003, 2004) and So (2005).…”

Abstract:In this paper, we present a novel algorithm for representing image content by constructing a hierarchy of semantic image regions, called a Semantic Segmentation Tree (SSeg-tree). First, the hill-manipulation algorithm divides an image into several visually coherent segments (small regions), which form the leaves of the SSeg-tree. Then, the method groups these segments based on well-defined spatio-visual grouping rules to produce bigger and more semantic regions, which form the intermediate nodes of the SSeg-tree. The SSeg-tree is a region-based description of the image semantic content that could be useful in many applications such as CBIR and filtering unwanted objects.
