Multimedia streaming applications have disruptively occupied bandwidth in wire line Internet, yet today's fledging mobile media streaming still poses many challenges in efficient content distribution due to the form of mobile devices. At the same time, cloud computing is gaining power as a promising technology to transform IT industry and many eminent enterprises are developing their own cloud infrastructures...
We evaluate the battery life of mobile devices that act as full-fledged peer nodes in a Kademlia DHT based P2P overlay network. The motivation is to find out how long a mobile peer is able to function in a UMTS or WLAN access network, and how the different parameter settings affect this battery life; this is interesting as mobile access to P2P networks is expected to become common in the near future...
Three data communication methods can be provided in a MANET: data broadcast, data query, and peer-to-peer messaging. The formation of heterogeneous distributed mobile databases within a MANET that allows people to submit queries or transactions is becoming a reality. Previously, the DD3M data communication protocol (distributed database with 3 communication modes) has been proposed for providing all...
As the mobile technology advances, various mobile peer-to-peer (P2P) systems have been developed. Since mobile devices have limited energy capacity, efficient use of the energy is indispensable for mobile P2P systems. In this paper, we propose an energy-efficient P2P system that is a type of the double-layered P2P systems in which files are searched mainly through the peers in the upper level, called...
Give a summary about the current e-commerce frame and its classical technologies. Afterwards, we analysis the existing e-commerce's operating mode; provide a net structure which expands to both PC and mobile devices as supplier or purchaser in it. In regardless of the fixed or the mobile peers, in this e-market, all defers to the p2p network form to carry on the organization completely. Any two participators...
This paper presents a novel mechanism that enables mobile devices to efficiently participate in Distributed Hash Tables (DHTs). By selectively dropping messages, we can significantly reduce traffic and thus the energy consumption of mobile nodes with only minor performance degradation. The protocol extension preserves compatibility with existing widely used DHT systems. We evaluate the solution by...
A rapidly growing number of carriers offer wireless video services to their customers, taking advantage of high quality video codecs implemented in dedicated hardware of selected mobile devices. In this paper we introduce a video conferencing software, which seamlessly integrates mobile with stationary users in a provider and device independent fashion. Innovations of this work are twofold. At first...
Mobile phones and related gadgets in networks are on the spot to deliver sufficient performance for rich multimedia applications and communication. In this report we introduce a video conferencing software, which seamlessly integrates mobile with stationary users into fully distributed multi-party conversations. Innovations related to this work are twofold. At first we report on a highly optimized...
