# A Novel Approach for Improving XML Querying over Wireless Broadcast Channels
## 1 Introduction  
Wireless broadcast channels are becoming increasingly popular for delivering large amounts of XML data to mobile devices in a variety of wireless network environments. Broadcasting data over a wireless channel adds index information that indicates when the data arrived. This is an energy-efficient option [1]. When the necessary data are available on the channel, indexing adds arrival information to it. The broadcast environment (single or multiple channels), data type (simple or XML), and broadcast schedule all have an impact on indexing approaches [2]. A single-channel environment only sends data items and indexes over one channel, as opposed to a multichannel environment, which transmits data across multiple channels. It is possible for a group of data items to be the same size or modifiable depending on the data type. The distribution of data across broadcast channels is determined by broadcast scheduling [3; 4; 5].  
The latency and bandwidth constraints associated with wireless broadcast channels make accessing XML data difficult.  
To address these issues, we propose a new XML data placement scheme that boosts the performance of XML querying over wireless broadcast channels. The proposed scheme partitions the XML data stream and distributes it across multiple channels, increasing parallelism and reducing access time during XML querying. Furthermore, the proposed scheme aids in balancing the load across different channels and improves fault tolerance and robustness in the face of network failures. This proposed work also discusses how the proposed scheme will be implemented, including partitioning criteria, query routingmechanisms, and challenges. Overall, the proposed XML data placement scheme shows promise for disseminating XML data via wireless broadcast channels, particularly in large-scale and data-intensive applications.  
This proposed scheme has the potential to improve energy efficiency in mobile devices by reducing the time and energy required for XML querying. Mobile devices can perform the required queries more efficiently by accessing multiple partitions of the XML data stream at the same time, reducing the amount of time and energy required to transmit and receive data via wireless broadcast channels.  
This scheme is widely applicable to a variety of applications involving large-scale, data-intensive XML data, including social networks, e-commerce, and healthcare. For example, in social networks, large amounts of XML data are generated and distributed among users, and the proposed scheme can help improve the performance and efficiency of XML querying in such systems. In e-commerce, this scheme can be used to distribute large product catalogs via wireless broadcast channels, allowing customers to search and browse more efficiently. In healthcare, this scheme can be used to disseminate patient data and medical records via wireless broadcast channels, allowing healthcare professionals to access medical information more quickly and efficiently [6; 7; 8].
