Efficient Processing of Text Searches Using Keywords on a Wireless Broadcast Channel

The rapid development of wireless network and powerful portable computer technologies has accelerated the development of mobile computing technologies and wireless information systems, thus resulting in the increased and widespread use of mobile computing devices. A large number of mobile users carrying portable devices will be able to access the information from anywhere and at any time. Energy and latency efficiency are two critical issues in wireless data broadcast system. Two basic performance metrics namely access time and tuning time are used to measure energy and latency efficiencies. In Wireless Environment broadcasting is an effective and scalable technique to disseminate information to large number of mobile clients. Several Indexing techniques are there for accessing data items on Broadcast channel it reduces the tuning time. Previously indexing methods were proposed for full text searches they are targeted for data in disk storage. For text searches in wireless broadcast channel, index scheme using keyword search will be implemented with the help of inverted list index method and full-text search algorithm And analysis of index scheme performance will be done with respect to latency. Index scheme will be implemented by using Java.
