Mobile Computing Ppt Presentation
If you host your own gateways, then it may be required to maintain some sort of connection with the mobile network. Examples are cost-based routing or video compression. Therefore, even as wireless networks improve their ability to deliver higher bandwidth, the power availability at the handset will still limit the effective throughput of data to and from the device. As according to the basic reference model only entities at the same level communicate with each other i. Additionally, the mobile node would have to notify all communication partners about the new address.
Thus, a host needs a so called topologically correct address. For example, as you approach a grocery store, it will remind you to pick up milk. The same holds for operating systems. Today, due to laptops or notebooks, e. Examples for mechanisms supporting user mobility are simple call-forwarding solutions known from the telephone or computer desktops supporting roaming i.
The fundamental difference lies in the fact that whereas academics and scientists started the Internet, adele i set fire to the rain mp3 the force behind mobile Internet access is the cash-rich mobile phone industry. Efficient utilization of mobile databases and gps in wireless networks Paper Presentation.
Mobile Cloud Computing amollg. Advantages of Mobile Cloud Computing. Most of the presentations and slideshows on PowerShow. You do not have the permission to view this presentation. Knowing that it is currently possible to use different networks, the software could choose the cheapest one.
So why not simply use a mobile computer in the Internet? Application of Mobile Cloud Computing.
PowerPoint Presentation On Mobile Computing
How to reduce power consumption? Most of the scenarios described in this book contain both user mobility and device portability at the same time. Looking at the number of computers connected to the Internet and at the growth rates of mobile communication, it is clear that a myriad device will participate in the Internet as mobile components.
The following explain the functions, of each layer in more detail in a wireless and mobile environment. According to Internet philosophy this is left to higher layers. The wire is replaced by the transmission of electromagnetic waves through the air although wireless transmission does not need any medium.
Therefore, additional mechanisms are necessary to inform these applications about mobility. In this scenario, a mobile network moving at high sped above ground with a wireless link will be the only means of transporting data to an from passengers. Therefore, the only effects of mobility should be a higher delay and lower bandwidth. Many mechanisms in the network and inside the device have to make sure that communication is still possible while it is moving.
WordPress Embed Customize Embed. The base station consists of a radio transceiver sender and receiver and an interworking unit connecting the wireless link with the fixed link. Routers within the Internet should not necessarily require other software. The report includes a discussion of the key vendors operating in this market.
How will people spend much of their time at work, during vacation? Thus, without user interaction the semantics of a closed door is applied to phone calls. This can be adapted for display on mobiles in a number of ways. You can choose whether to allow people to download your original PowerPoint presentations and photo slideshows for a fee or free or not at all. Some of them are given as follows.
This approach does not work if the mobile node moves quite often. Finally, the applications are situated on top of all transmission oriented layers. What will computers look like in ten years, in the next country? Introduction to Computers - What Is a Computer?
Reception in tunnels and some buildings is poor. This third layer is responsible for routing packets through a network or establishing a connection between two entities over many other intermediate systems.
While it is theoretically possible to change all routing tables all over the world to create specific routes to a mobile node, this does not scale at all with the number of nodes in the Internet. Mobile device characteristics and limitations. Furthermore, special care has to be taken considering the lower bandwidth of wireless links.
Mobile Internet access surely is poised to be a major commercial success. It is responsible for a reliable point-to-point connection between two devices or a point-to-multipoint connection between one sender and several receivers. Power consumption Mobile computers must rely entirely on battery power. Presentation Description Mobile Cloud Computing. View by Category Toggle navigation.
