In wireless sensor network Injecting invalid data attack is very crucial issue. If invalid data is stored in sink than due to error decision waste of energy and bandwidth will take place. This book proposes a new reliable scheme (EBCAS) to tackle this crucial issue (invalid data attack) in wireless sensor network which is help in power optimization and efficient bandwidth consumption base on message authentication code (MAC).This scheme results shows the ability to improve the performance and accuracy through draining the injected invalid data.

This book consist a technique where Mobile phone acts as a server. Here server and browser are connected threw IP address. A person who is connected to that mobile server and who want to watch live image then he can send a request and images clicked by that mobile server. This technique can be used in sting operation. In addition, for improving the competence of data gathering, its necessary that a new mobile phone search engine is needed when user done searching in grouping with live click.
