MOBILE NETWORKING

              This paper mainly explains about mobile networking.Its types advantages  and disadvantages are all explains in this paper.Mobile network  is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently.

                  Mobile can be used alone (for example in the military) or as a hybrid together with the Internet or other networks. Different mobile applications have different needs, and hence the various mobile routing protocols may be suitable in different areas. The size of the network and the frequency of the change in topology are factors that affect the choice of the protocols. There is no best protocol for all applications.

           To accommodate the changing topology special routing algorithms are needed. For relatively small networks flat routing protocols may be sufficient. However, in larger networks either hierarchical or geographic routing protocols are needed. There is no single protocol that fits all networks perfectly. The protocols have to be chosen according to network characteristics, such as density, size and the mobility of the nodes.Mobile does not require any fixed infrastructure, such as a base station, therefore, it is an attractive option for connecting devices quickly and spontaneous.  Mobile commerce (m-commerce) is an emerging discipline involving applications, mobile devices, middleware, and wireless networks. While most of existing e-commerce applications can be modified to run in a wireless environment, m-commerce also involves many more new applications that become possible only due to the wireless infrastructure.

 

 

 

 

INTRODUCTION

            Information technology is rapidly changing from regular desktop computing, where isolated workstations communicate through shared servers in a fixed network, to an environment where a large number of different platforms communicate over multiple network platforms. In this environment the devices adapt and reconfigure themselves individually and collectively, to support the requirements of mobile workers and work teams.

            Mobile Networks  consist of nodes that change position frequently. To accommodate the changing topology special routing algorithms are needed. For relatively small networks flat routing protocols may be sufficient. However, in larger networks either hierarchical or geographic routing protocols are needed. There is no single protocol that fits all networks perfectly. The protocols have to be chosen according to network characteristics, such as density, size and the mobility of the nodes.

      Mobile  networking is one of the more innovative and challenging areas of wireless networking, one which promises to become increasingly present in our lives. Consisting of devices that are autonomously self-organizing in networks, ad hoc networks offer a large degree of freedom at a lower cost than other networking solutions.

MOBILE NETWORKING

        

     Mobile networking refers to technology that can support voice and/or data network connectivity.using wireless, via a radio transmission solution. The most familiar application of mobile networking is the mobile phone. In the past, wireless communications predominantly used circuit switching to

carry voice over a network; however, more recently both voice and data are being transmitted over both circuit-switched and packet-switched networks.

The radio spectrum allocated to mobile networks has expanded over time. Below is a summary of the generations of mobile networking.
