# A Novel Approach for Improving XML Querying over Wireless Broadcast Channels
## 3 Proposed Work
### Architecture Diagram for Proposed XML Querying Scheme  
Figure 2 depicts the proposed architecture for the XML querying scheme. The diagram depicts a straightforward method for partitioning an XML data stream based on a specified criterion. Any wireless device can submit a query to the server via a Query Interface. The query is then routed to the appropriate channel, allowing the XML data source to return the result. These results are gathered and combined using an XML query result aggregator. The final result is then sent to the specified wireless client. The steps ensure that the data are divided into partitions that reflect the distinct values of the chosen criterion, allowing for more efficient processing and querying. The steps for the XML data partition and broadcasting in the architecture of the proposed XML querying scheme as per the data access algorithm are as follows:  
1. Reading the XML Data Stream: * The system starts by reading the input XML data stream. 2. Choose Partitioning Criterion: * Select the criterion for partitioning, such as document size, document type, or document content. 3. For Each Document in the XML Data Stream: * Iterate through each document in the XML data stream. 4. Determine the Value of the Chosen Criterion: * For each document, determine the value of the chosen partitioning criterion. To partition an XML data stream, first read the input XML data stream. The system begins by ingesting and preparing this stream for processing. Next, a partitioning criterion is chosen, which could be based on document size, type, or content. Once the criterion is determined, the system iterates through each document in the XML data stream. It assigns a value to each document based on the partitioning criterion. Based on these values, the system generates a separate partition for each unique criterion value. Each document is then assigned to the partition corresponding to its specific criterion value. This process is repeated for each document in the XML data stream. It ensures that each document is correctly assigned to the appropriate partition. Finally, the partitions are output as separate XML data streams, with each representing a subset of the original data based on the partitioning criterion used. This methodical approach ensures that the XML data are efficiently organized for future querying and processing. The steps for the XML query routing mechanism in the architecture of the proposed XML querying scheme as per the data access algorithm are as follows:  
1. Divide the XML Data Stream:  
* XML Data Source: The origin of the XML data stream. Figure 2: The architecture of the proposed XML querying scheme. Partitioning Process: The data stream is divided into several partitions based on predefined criteria such as document size, type, or content. 2. Assign Partitions to Wireless Broadcast Channels: * Each partition is assigned to a different wireless broadcast channel, ensuring balanced load distribution across all channels. 3. Broadcast the XML Data Partitions: * Wireless Broadcast Channels: Each channel broadcasts its assigned XML data partition. 4. Implement Query Routing Mechanism: * Query Router: Directs user queries to the appropriate channels. * Query Interface: Where users input their queries. * Routing Logic: Routes the query to the relevant channel or channels based on the XML data partitions they contain. * Result Collection and Combination: Collect results from each channel and combine them to generate the final query result. 5. Result Delivery: Returns the combined query results to the user. The proposed scheme for improving XML querying over wireless broadcast channels consists of several key steps. To begin, the XML data stream, which originates from an XML data source, is partitioned based on predefined criteria such as document size, type, and content. This partitioning process organizes the data for efficient querying. Next, each partition is assigned to a different wireless broadcast channel to ensure that the load is distributed evenly across all channels.
