This paper gives the </p><p>idea and general overview of multimedia database their </p><p>issues of multimedia database systems considering new </p><p>area of Cloud Computing. Different types of multimedia </p><p>databases their queries and to retrieve the data from </p><p>database. Different types of architecture of multimedia </p><p>databases are also discussed. Paper cover all the basic </p><p>concepts of multimedia database. Mobile cloud computing </p><p>is one of mobile technology trends in the future since it </p><p>combines the advantages of both mobile computing and </p><p>cloud computing, thereby providing optimal services for </p><p>mobile users. </p><p>Keywords: Mobile Multimedia databases, Mobile cloud computing </p><p>INTRODUCTION </p><p>Multimedia database is a database that hosts one or more </p><p>primary media file types such as .txt (documents), .jpg </p><p>(images), .swf (videos), .mp3 (audio), etc. and loosely fall </p><p>into three main categories: </p><p> Static media (time-independent, i.e. images and handwriting) </p><p> Dynamic media (time-dependent, i.e. video and sound bytes) </p><p> Dimensional media (i.e. 3D games or computer-aided drafting programs- CAD) </p><p>All primary media files are stored in binary strings of </p><p>zeros and ones, and are encoded according to file type. </p><p>The term "data" is typically referenced from the computer </p><p>point of view, whereas the term "multimedia" is </p><p>referenced from the user point of view. </p><p>TYPES OF MULTIMEDIA DATABASES </p><p>There are numerous different types of multimedia </p><p>databases, including: </p><p>a) The Authentication Multimedia Database (also known as a Verification Multimedia Database, i.e. </p><p>retina scanning), is a 1:1 data comparison </p><p>b) The Identification Multimedia Database is a data comparison of one-to-many (i.e. passwords and </p><p>personal identification numbers. </p><p>c) A newly-emerging type of multimedia database, is the Biometrics Multimedia Database; which </p><p>specializes in automatic human verification based </p><p>on the algorithms of their behavioral or </p><p>physiological profile. </p><p>This method of identification is superior to traditional </p><p>multimedia database methods requiring the typical input </p><p>of personal identification numbers and passwords due to </p><p>the fact that the person being identified does not need to </p><p>be physically present, where the identification check is </p><p>taking place. This removes the need for the person being </p><p>scanned to remember a PIN or password. Fingerprint </p><p>identification technology is also based on this type of </p><p>multimedia database. </p><p>COMPONENTS OF A MULTIMEDIA </p><p>SYSTEM: </p><p>The Hardware and Software Components required for a </p><p>multimedia system are: </p><p>(a) Capture a device which has a wide variety of range </p><p>including Video Camera, Video Recorder, Audio, </p><p>Microphone, Keyboards, mice, graphics tablets, 3D </p><p>input devices, tactile sensors, VR devices. </p><p>Digitizing Hardware etc. </p><p>(b) Communication Networks includes Local Networks, </p><p>Intranets, Internet, Multimedia or other special high </p><p>speed networks. </p><p>(c) Storage Devices such as Hard disks, CD-ROMs, </p><p>DVDROM, etc. </p><p>(d) Display Devices like CD-quality speakers, HDTV, </p><p>SVGA, Hi-Resolution monitors, Color printers etc. </p><p>(e) Computer Systems like Multimedia Desktop </p><p>machines, Workstations, MPEG/ VIDEO/DSP </p><p>Hardware etc. </p><p>DIFFICULTIES INVOLVED WITH </p><p>MULTIMEDIA DATABASES </p><p> The difficulty of making these different types of </p><p>multimedia databases readily accessible to humans is: </p><p></p></li><li><p>International Journal of IT, Engineering and Applied Sciences Research (IJIEASR) ISSN: 2319-4413 Volume 2, No. 6, June 2013 </p><p>i-Xplore International Research Journal Consortium </p><p>9 </p><p>a) The tremendous amount of bandwidth they consume; </p><p>b) Creating Globally-accepted data-handling platforms, such as Joomla, and the special </p><p>considerations that these new multimedia database </p><p>structures require. </p><p>c) Creating a Globally-accepted operating system, including applicable storage and resource </p><p>management programs need to accommodate the </p><p>vast Global multimedia information hunger. </p><p>d) Multimedia databases need to take into accommodate various human interfaces to handle </p><p>3D-interactive objects, in an logically-perceived </p><p>manner (i.e. </p><p>e) Accommodating the vast resources required to utilize artificial intelligence to it's fullest potential- </p><p>including computer sight and sound analysis </p><p>methods. </p><p>f) The historic relational databases (i.e the Binary Large Objects BLOBs- developed for SQL </p><p>databases to store multimedia data) do not </p><p>conveniently support content-based searches for </p><p>multimedia content. </p><p>This is due to the relational database not being able to </p><p>recognize the internal structure of a Binary Large Object </p><p>and therefore internal multimedia data components cannot </p><p>be retrieved. </p><p>Basically, a relational database is an "everything or </p><p>nothing" structure- with files retrieved and stored as a </p><p>whole, which makes a relational database completely </p><p>inefficient for making multimedia data easily accessible to </p><p>humans. </p><p>In order to effectively accommodate multimedia data, a </p><p>database management system, such as an Object Oriented </p><p>Database (OODB) or Object Relational Database </p><p>Management System (ORDBMS). Examples of Object </p><p>Relational Database Management Systems include </p><p>Odaptor (HP): UniSQL, ODB-II, and Illustra. </p><p>The flip-side of the coin, is that unlike non-multimedia </p><p>data stored in relational databases, multimedia data cannot </p><p>be easily indexed, retrieved or classified, except by way of </p><p>social bookmarking and ranking-rating, by actual humans. </p><p>This is made possible by metadata retrieval methods, </p><p>commonly referred to as tags, and tagging. This is why we </p><p>can search for dogs, as an example, and a picture comes </p><p>up based on your text search tem. This is also referred to a </p><p>schematic mode. Whereas doing a search with a picture of </p><p>a dog to locate other dog pictures is referred to as </p><p>paradigmatic mode. </p><p>However, metadata retrieval, search, and identify methods </p><p>severely lack in being able to properly define uniform </p><p>space and texture descriptions, such as the spatial </p><p>relationships between 3D objects, etc. The Content-Based </p><p>Retrieval multimedia database search method (CBR), </p><p>however, is specifically based on these types of searches. </p><p>In other words, if you were to search an image or sub-</p><p>image; you would then be shown other images or sub-</p><p>images that related in some way to your the particular </p><p>search, by way of color ratio or pattern, etc. </p><p>MOBILE CLOUD COMPUTING AS A </p><p>FUTURE OF MOBILE MULTIMEDIA </p><p>DATABASE </p><p> Cloud computing (CC) has been widely recognized as the </p><p>next generations computing infrastructure offers some </p><p>advantages by allowing users to use infrastructure (e.g., </p><p>servers, networks, and storages), platforms (e.g., </p><p>middleware services and operating systems), and </p><p>softwares (e.g., application programs). Most of Mobile </p><p>devices (smartphone, mobiles, tablet pcs, etc) are </p><p>increasingly becoming an essential part of human life as </p><p>the most effective and convenient communication tools </p><p>not bounded by time and place. </p><p>Mobile users accumulate rich experience of various </p><p>services from mobile applications (e.g., iPhone apps, </p><p>Google apps, etc), which run on the devices and/or on </p><p>remote servers via wireless networks. The rapid progress </p><p>of mobile computing (MC) becomes a powerful trend in </p><p>the development of IT technology as well as commerce </p><p>and industry fields. However, the mobile devices are </p><p>facing many challenges in their resources (e.g., battery </p><p>life, storage, and bandwidth) and communications (e.g., </p><p>mobility and security) . The limited resources significantly </p><p>impede the improvement of service qualities. </p><p>According to the latest study from Juniper Research, the </p><p>market for cloud-based mobile applications will grow </p><p>88% from 2009 to 2014. The market was just over $400 </p><p>million this past year, says Juniper, but by 2014 it will </p><p>reach $9.5 billion. </p><p>MOBILE MULTIMEDIA CHALLENGES </p><p> Multimedia data are consists of images, audio, text and </p><p>video it requires large amount of storage and fast speed </p><p>for transferring data. For storing and managing data </p><p>different types of devices and equipments are required in </p><p>heterogeneous mobile environment. Data retrieval and to </p><p>providing multimedia content to mobile devices are </p><p>frequent device disconnection as in mobile environment </p><p>connection breaks frequently that leads to the issue of </p><p>synchronization and consistency. Although speed of </p><p></p></li><li><p>International Journal of IT, Engineering and Applied Sciences Research (IJIEASR) ISSN: 2319-4413 Volume 2, No. 6, June 2013 </p><p>i-Xplore International Research Journal Consortium </p><p>10 </p><p>Internet improved a lot in recent year with advancement </p><p>of technology, but still there is need of improvement. </p><p>Other issues are poor performance, limitation of </p><p>communication bandwidth, limitation of the database </p><p>model, data consistency, synchronization, limited device </p><p>storage and other resource constraints. An issue of </p><p>security and privacy is also important as data in mobile </p><p>environment is broadcast; this may leads to issues of </p><p>security and privacy of data. </p><p>ARCHITECTURES OF MOBILE </p><p>MULTIMEDIA CLOUD COMPUTING </p><p>From the concept of Mobile Cloud Computing devices are </p><p>connected to mobile networks via base station ( BTS -</p><p>Base Transfer Receiver, access point or satellite that </p><p>establish and control the connections and functional </p><p>interfaces between the network and mobile devices. </p><p>Mobile user's requests and information are transmitted to </p><p>the central processor that are connected to servers </p><p>providing mobile network services. Mobile Network </p><p>operators can provide service to mobile users based on </p><p>home agent and subscribers data stored in databases. </p><p>Fig. 1. Mobile Cloud Computing (MCC) architecture. </p><p>After that, the subscribers requests are delivered to a </p><p>cloud through the Internet. In the cloud, cloud controllers </p><p>process the requests to provide mobile users with the </p><p>corresponding cloud services. These services are </p><p>developed with the concepts of utility computing, </p><p>virtualization, and service-oriented architecture (e.g., web, </p><p>application, and database servers). </p><p>APPLICATIONS OF CLOUD </p><p>COMPUTING </p><p> Cloud computing is one of the most promising </p><p>technologies in the modern day world. Several companies </p><p>have already popped in the cloud market and achieved </p><p>desired goals they planned for their businesss expansion. </p><p>To add more to clouds importance in the growing IT </p><p>industry let us check on some of its uses and benefits that </p><p>it offers to its users. </p><p>1. Cloud Follows Pay for What we use Model </p><p>This particular characteristic of cloud focus on the fact </p><p>that cloud computing and managed cloud services are </p><p>truly cost-effective. This means users will have to pay </p><p>only for the amount of service used by them. This way, </p><p>money spent on improving business through cloud doesnt </p><p>prove to be expensive. SMBs are benefited the most with </p><p>such a type of facility that cloud offers. </p><p>2. (24*7) Availability and Performance Oriented </p><p>Infrastructure </p><p>When we talk about cloud, one thing that concerns us is </p><p>whether such a technology can cater to the clients needs </p><p>or whether it can create a highly scalable environment. If </p><p>such questions boggle your mind, dont worry as managed </p><p>cloud services will do it for you. Things like cloud </p><p>monitoring, cloud migration of data from one server to the </p><p>cloud server etc among others are two of the activities that </p><p>are catered by managed cloud service providers. </p><p>3. Cloud Technology believes in Optimization of </p><p>Existing Resources If company is facing hard time in managing hardware and </p><p>software stuff. Servers are running extremely low and </p><p>there is not enough space left for any new data to be </p><p>stored. To overcome such a situation, cloud services are </p><p>introduced so that existing servers get rest from the over </p><p>loaded traffic and work environment of the company </p><p>becomes more synchronized. By doing so, not only the </p><p>resources get optimized but with the help of managed </p><p>cloud services businesses are able to focus on other </p><p>business related activities as well. </p><p>4. Organizations Experience Device Independence </p><p>When we say that by putting everything on cloud can </p><p>reduce your worry of keeping a track of hardware and </p><p>software devices, we probably want to make your existing </p><p></p></li><li><p>International Journal of IT, Engineering and Applied Sciences Research (IJIEASR) ISSN: 2319-4413 Volume 2, No. 6, June 2013 </p><p>i-Xplore International Research Journal Consortium </p><p>11 </p><p>physical world into a virtual one. With managed cloud </p><p>services you dont have to bother about whats going on in </p><p>your in-house IT premises. </p><p>Let your cloud manager do the burdensome work and help </p><p>you get rid of all the expensive hardware and software that </p><p>cost you almost an arm or a leg. </p><p> 5. Disaster Recovery Plan Help to Restore Data </p><p>Quickly on Cloud </p><p>For every cloud to be a successful one, pre-configured </p><p>disaster recovery plan is must. Cloud disaster recovery </p><p>plan works automatically at the time a server or data </p><p>crashes and help in restoring at the earliest. Incorporating </p><p>such applications makes cloud an efficient platform for </p><p>managing IaaS, PaaS and SaaS competitively. </p><p>6.Agile Development on Cloud </p><p>Agility in business operations comes with effective and </p><p>efficient tools that help in constructing a strong and </p><p>construing business or work environment. This is due to </p><p>the fact that cloud technology is built on norms like </p><p>understanding service-level agreements or SLAs, </p><p>developing various strategies to understand the business </p><p>as a whole and then improvising as well as analyzing the </p><p>steps necessary for keep the businesses running smoothly. </p><p>7.
