# A Novel Approach for Improving XML Querying over Wireless Broadcast Channels
## 6 Conclusions  
With the proliferation of mobile devices and wireless networks, accessing and querying large amounts of data via wireless broadcast channels has become critical. XML is a popular data format for representing and exchanging data. Querying XML data is a critical task

Wireless broadcast channels, however, may produce high latency, poor bandwidth utilization, and poor energy efficiency when querying large XML datasets. To address these issues, we proposed an approach for improving XML querying over wireless broadcast channels. The proposed scheme incorporates key parameters like data partitioning, load balancing, query routing, and result aggregation. The proposed scheme involves partitioning the XML data stream into several partitions based on criteria such as document size, type, or content. The proposed scheme assigns each partition to a separate wireless broadcast channel to balance the load on each channel. The proposed scheme also includes a query routing mechanism, which can route queries to the appropriate channel or combination of channels. These channels include the relevant XML data partition. In our comparative study, we compared the performance of the proposed scheme for improving XML querying over wireless broadcast channels. The proposed scheme balances partitioning, transmission, routing, and processing times, giving it a competitive advantage in scenarios requiring optimal access times. The proposed scheme takes a balanced approach, with moderate query response time, efficient network traffic, and balanced resource utilization. The proposed scheme reduces transmission time by partitioning the XML data and balancing the load across multiple wireless broadcast channels. While efficiently routing and processing queries, this resulted in a total access time of 12 s, compared to 14 s for both centralized querying and unpartitioned broadcasting. The proposed scheme significantly reduces query response time when compared to centralized querying and unpartitioned broadcasting. This scheme reduces latency when accessing large XML documents by partitioning the data stream and distributing it across multiple wireless broadcast channels. In the future, dynamic factors like network congestion or varying query loads over wireless broadcast channels will be incorporated. As a result, the system may become even more resilient and adaptable to the real world. Lower access times and more balanced resource utilization across a variety of network environments and usage scenarios would be possible for the system if it could adjust to these dynamic factors.
