摘要：In order to enhance the scalability o f the system using the computational capabilities of the mobile devices Wireless data broadcast is an important technique. Under this e nvir onme nt, this application contains a central server who plays an important role by processing the query send by the registered user with finding the Nearest Neighbours of the registered user using kNN algorithm .This mainly uses broadcast technique for dissemination the result to Nearest Neighbours. The target is to reduce the power consumption and complexity at the client side. This application can be used for M etropolitan citie s for r ailway-timetable applic ation in orde r to obtain the trai n timetable and shorte st path to re ach the r equi red destination w hic h hel ps any unknown user to tra vel in metro po litan c ity. This is the study that 1) addresses continuous queries and 2) considers moving data objects. A challenging problem is to design cost models for monitoring spatial queries processing in wireless broadcast environments. Such models could reveal the best technique for the given problem settings e.g. to decrease the Server and Client complexity and enhances t he e x i s t i n g tec hniques in terms of energy consumption, while achieving low access latency
