MOBILE MESSAGING USING WI-FI ADHOC NETWORK

Today mobile is very useful thing. It is need of everybody. Mobile phones provide one big application that is the SMS. But it not free of cost so we have to make one application which gives free chatting with others with no cost. The problem is that when employing a 3G wireless data connection and uploading to a traditional web server, these transfers can quickly become prohibitively expensive. Users are typically subject to wireless data plans with finite usage limits and steep overage charges. The alternative of uploading content through a wired USB connection is cumbersome and delays the user experience.
