The paper analyzes the immense popularity of social media over mobile devices and prospects the new theme of location based mobile - social networking.
The document discusses the evolution of smart objects from simple artifacts to complex machines, mass-produced products, customizable gizmos, and eventually SPIMES (smart objects defined by their digital information rather than physical form). It describes how SPIMES will interact through an "Internet of Things" enabled by identification technologies like RFID. The document outlines both benefits and concerns of a world where everyday objects are connected and trackable through global information networks.
In the future, technology will be even more advanced and integrated into our lives. By 2025, all smartphones will come paired with customizable watch phones that allow users to access all phone features from their wrist. Home devices like the Home Kinect will recognize users through facial detection and provide assistance with daily tasks, schedules, home security, and more through voice commands. In education, the iLearn laptop will replace physical textbooks and notebooks, allowing students to access all course materials digitally from anywhere through built-in WiFi. These new technologies will further social learning and media dependency as people increasingly rely on devices to stay connected.
Decentralized Social Networks - WebVisions 2009David Recordon

Peer To Peer Content Sharing On Wi-Fi Network For Smart PhonesIOSR Journals
This document summarizes a research paper on peer-to-peer content sharing on Wi-Fi networks for smart phones. It discusses using a peer-to-peer model to allow smart phones to share content like videos and photos over Wi-Fi networks without using cellular data or requiring a central server. The proposed system would allow phones to discover each other on the local network, search for files, and download content directly from other peers. This approach aims to reduce costs and bandwidth usage compared to uploading content through cellular networks or wired connections.
Wi-Fi, also known as wireless fidelity, is a technology that allows electronic devices to connect to the internet or communicate with each other wirelessly within a particular area. It uses radio waves to transmit and receive data over short distances. The technology was invented in 1991 and has since evolved through several generations with improved speeds and capabilities. Wi-Fi networks provide connectivity in homes, businesses, and public places through wireless routers and hotspots. While convenient, Wi-Fi also presents some security and interference concerns to consider.
This document describes a Wi-Fi Direct peer-to-peer (P2P) messenger and browser application for Android devices that allows private communication without relying on internet or cellular networks. The application uses Wi-Fi Direct to enable two Android devices to connect and send encrypted messages to each other. It also allows one device to act as a server, downloading web pages through its internet connection and sending them to the other device. While the prototype accomplishes the goals of direct device communication and limited web browsing, the authors discuss improvements including implementing true end-to-end encryption and expanding the network to multiple devices over a longer range using alternative protocols.

This document provides an overview of computer networks, including:
- Defining what a computer network is as a system that connects computing devices to transmit and share information.
- Describing examples of computer networks like traffic monitoring systems and collaboration software.
- Explaining key components of computer networks like network devices, links, communication protocols, and network defense.
- Detailing types of computer networks based on geographical scale like personal area networks, local area networks, and wide area networks.
- Outlining advantages like improved communication and resource sharing as well as disadvantages like security difficulties.
A computer network allows electronic devices to connect and share resources through wireless or wired connections. Networks can be as simple as two computers sharing files or as large as networks spanning businesses, schools, and globally with the Internet. Larger networks are more complex and may require network software and servers to manage connections and security between thousands of devices. The basic components of a home network typically include a computer, modem, router, and optionally a printer to share an Internet connection and resources between devices in a home.
A computer network connects multiple computers together to allow them to communicate and share resources. The basic building blocks of a network include computers equipped with network ports, cables to connect the computers, and a network switch for them to plug into. Larger networks may include additional components like routers or repeaters. Computer networks provide benefits such as hardware and data sharing between connected devices, enhanced real-time communication, collaborative work environments, access to shared programs stored on servers, and increased storage capacity from network-attached devices. However, networks also pose security threats from hacking or data theft, single point of failures if the main server crashes, and potential virus or malware spread throughout the connected systems. Proper technical skills are required to administer large computer networks
The document discusses how semantic computing in the cloud will revolutionize the consumer experience on mobile phones. It argues that cloud computing will allow for more powerful interfaces on phones that understand natural language, perceive the environment through sensors, and help solve everyday problems. By connecting open data and APIs in the cloud, mobile phones can act as virtual personal assistants that understand speech, provide location-aware information and services, and apply multiple sources to address users' needs.
Service Based Content Sharing in the Environment of Mobile Ad-hoc NetworksIOSR Journals
This document discusses service-based content sharing in mobile ad-hoc networks. It proposes a peer-to-peer file sharing system that allows efficient content distribution using low-cost Bluetooth links. Peers discover each other via scanning and share subscribed content in segments over Bluetooth. The system was implemented on Blackberry and Windows Mobile smartphones to test feasibility. Tests showed file transfers were practical between mobile devices using this approach, with segment size having little effect on performance.
