Literature Review Title: Mobile Multimedia Recommendation in Smart Communities: A Survey 
Chapter Title:  I. INTRODUCTION 
1. Abstract of Cited Paper (BIB001):  Mobile TV provides multimedia contents to the user by wireless communication. Here the personalized recommendation system allows the users to easily select the contents wanting to access. In this paper we propose a personalized recommendation scheme which considers the activities of the user at runtime and the information on the environment around the user. It allows efficient operation in mobile device, and interoperability between the TV multimedia metadata and ontology. The accuracy of the proposed scheme is evaluated by an experiment, which reveals a significant improvement compared to the existing schemes. 
2. Abstract of Cited Paper (BIB002):  There is a growing trend towards the convergence of cyber-physical systems (CPS) and social computing, which will lead to the emergence of smart communities composed of various objects (including both human individuals and physical things) that interact and cooperate with each other. These smart communities promise to enable a number of innovative applications and services that will improve the quality of life. This position paper addresses some opportunities and challenges of building smart communities characterized by cyber-physical and social intelligence. 
3. Abstract of Cited Paper (BIB003):  Mobile phone sensing is an emerging area of interest for researchers as smart phones are becoming the core communication device in people's everyday lives. Sensor enabled mobile phones or smart phones are hovering to be at the center of a next revolution in social networks, green applications, global environmental monitoring, personal and community healthcare, sensor augmented gaming, virtual reality and smart transportation systems. More and more organizations and people are discovering how mobile phones can be used for social impact, including how to use mobile technology for environmental protection, sensing, and to leverage just-in-time information to make our movements and actions more environmentally friendly. In this paper we have described comprehensively all those systems which are using smart phones and mobile phone sensors for humans good will and better human phone interaction.

Literature Review:
HEcurrent growth and tremendous proliferation of mobile devices has paved the way for accessing and capturing different types of multimedia contents (e.g. text, images, audios and videos). Generations of mobile devices started from analogue and migrated to digital. Mobile multimedia contents began with text and later generated to still images, animation, audio and video. Currently, different types of multimedia contents are available due to diverse generations of mobile devices, namely, the first generation (1G), second generation (2G), third generation (3G) and forth generation (4G) BIB002 -  . As a result of technological trends and changes, modern computers are becoming portable, smaller and thus mobile. These modern computers are equipped with higher performance in terms of computational processing speed, memory size etc. Some examples of new forms of computers include smartphones, tablets, and personal digital assistants (PDAs). Many physical things will possess computing and communication capabilities of different levels, which are provided by small and perhaps invisible computers embedded therein. This resultant incorporation of networked computing and physical dynamics has led to the emergence of Cyber-Physical Systems (CPS), which have become a very interesting area for research in recent years. The growing trends towards the convergence of CPS and social computing have led to the emergence of smart communities. They are usually composed of physical objects/things and human beings that interact and cooperate with each other. Smart communities promise to support a number of state-of-the-art applications and services that will improve the quality of life BIB003  . Mobile devices are well on their way of becoming personal and sensing platforms. They were primarily used solely as communication devices but can now be used to access and capture multimedia contents for wide range of activities in smart communities BIB004 BIB001 . In academia and education, mobile devices are used for mobile social learning. During events such as conferences and workshops, mobile devices can be used as an event guides for the planner, organizers and attendees. In other activities which involve context-aware services such as entertainment, shopping, tourism and location-based activities, mobile devices play different and important roles for individual users. Mobile devices used in such smart communities have limited storage and can therefore not store a lot of multimedia contents for users. Nowadays multimedia contents are becoming more prevalent in mobile devices, making them an advantageous gateway for the individual. In order to curb multimedia information overload and to allow users to have access to relevant multimedia contents in their mobile devices, today's main focus and challenges of researchers is on how to develop multimedia recommender systems for mobile devices. Furthermore, users of mobile devices in smart communities have different interest, preferences, tastes and demography and would usually like to store multimedia contents that are only relevant to them. It is however not easy for users to search or manage large volumes of multimedia contents in a mobile device with limited resources such as storage. To corroborate the importance of
