Abstract: A technology like dynamic mobile computing allows transmission of data, via. a computer or any computing device, without having to be connected to a physical link. Mobile voice communication is widely established throughout the world and has had a very rapid increase in the number of subscribers to the various cellular networks over the last few years. An extension of this technology is the ability to send and receive data across these cellular networks. Now these days the mobile computing is a main source of communication for any purpose. It is with the growing pace of communication and globalization, sources of data communication have been growing in all the sectors. Now a days, one of the fast growing spot in the stream of communication is the Wireless and Mobile Technology. But it has also some constraints to be avoided, many challenges will come while working with mobile computing, there are many open issues going, to be solved to increase the total progress of the mobile computing. While with the growing pace of the mobile computing we need to insure the issue that is happening like the security issue, these day’s people are doing their money transaction on the mobile itself and it carries highly credential data, so, it must be secured from the outside of the world. M-commerce is totally based on the concept of the mobile computing and uses the mobile device for the transaction but there are some limitation with all these stuff and we have to keep in mind while working with these devices. The goal of this project to find out the limitations, characteristics, applications, issues of mobile computing and new field where this technology will be useful and the technology used for the communication and networking.
