Abstract-The main theme of this research paper includes a brief introduction to our project “Android Wi-Fi Peer-to-Peer Networking”. The purpose of this research is to design and implement a telephony program that uses Wi-Fi in P2P (Peer-to-Peer) as a means of communication between mobile phones at no cost. The system will allow users to search for other individuals within Wi-Fi range and to establish free P2P voice connections, or to establish virtual connection through Access Points (AP). It allows devices to communicate with one another enabling rich peerto-peer social applications. We will present how a mobile peer-to-peer file-sharing application can be implemented using the Session Initiation Protocol (SIP) as the underlying signaling protocol.
Keywords- Android; Wi-Fi; SIP; Java; P2P; NAT; JXTA; IMS; API

networks by using SIP with some enhancements as the P2P signaling protocol. This thesis is divided into two parts. In the first part, different P2P architectures and search algorithms are presented, in the second part, hybrid mobile P2P architecture consisting of a Android based mobile client and a SIP Application Server based super-peer are presented. In addition, voice call will be supported using Wi-Fi to allow mobile phones to communicate free of cost to each other through P2P or through AP.

II. WHY ANDROID? Android Operating System has advantages,

    We aim to be the expert in file-sharing gadgets between any electronic devices. We decided to first begin by developing a device called the iShare, which enables music sharing between the Apple iPods/iPhones before we go further and make similar products for other brands like Samsung and HTC in the future. The target market for iShare is mainly the Thai middle-to-upper-class, younger generation who owns an iPod/iPhone and have solid income to spend on this innovative gadget. Our market size is carefully calculated to be approximately 200,000,000 THB for the iShare alone and up to 1,000,000,000 THB in total. Our direct competitor is miShare LLC, which offers a similar product to customers in the US and Europe. Indirect competitors include other computer programs that enable…

    Over the last decade, electronic-based companies such as Samsung and Apple have collaborated with cellular-phone carriers, and have studied the average consumer to find endless ways to improve the cellular phone. As a result, the smart phone was born. With their ability to provide users with instant access to communication, entertainment, Internet access, calendar, news, social media, and much more, the smart phone revolutionized and shifted the path of modern technology. In 2006, Apple began this revolution with their release of the iPhone. Being the first proper smart phone, many other companies attempted to mimic the unbeatable features and technology that Apple had included with the iPhone. Though many had failed in doing so, Google managed to keep up with the iPhone with their Android software. Soon enough, Google’s Android software became the dominant smart phone based software for smart phones not manufactured by Apple. Because of this, Android phones had become just as popular as iPhones. This paper will explore the similarities and differences between both Apple’s iPhone and Google’s Android.…
