As people increasingly capture more digital media, users want to share them easily without complex setup and manipulation. We propose an intuitive and direct means for sharing files between mobile devices: placing devices together and dragging a file directly from one screen to the other. Our approach allows users a mutual operation, and it is scalable to number of devices. We designed several such...
Due to the development and maturity of mobile devices and wireless network techniques, mobile devices have become the most personal medium available, and have led to new marketing applications and activities. Mobile advertising is considered as the most potential business field of the future. This study investigated the presentation effects of mobile advertising upon texts, images, and films by experimentation,...
This paper proposes a secure mobile content delivery architecture in an integrated, hybrid network environment. Its design comprises device discovery, asynchronous content delivery, secure access control and virtual file system with dynamic reference mapping mechanisms, which are able to alleviate several inherent limitations in wireless and mobile networks. It thus enables mobile handheld devices...
Recently, Lee et al. proposed a remote authentication model of information appliances (RAMIA). Unfortunately, RAMIA has a fatal error that opens the entire home network of information appliances to hackers. In this paper, we propose a new secure remote control model for information appliances (SRCMIA) to fix this error. Besides, our model can also achieve both message authentication and one-time secret...
This paper describes how we can use existing mobile technology to track the vehicle. Here the embedded system along with the mobile is used to prevent the vehicle from being stolen and also if the vehicle is stolen then its location can be tracked. Mobile technology is the fastest growing communication mode. In todaypsilas mobile technology we all are acquainted with short message service (SMS). In...
This contribution addresses the case when live packet-switched video is used to enrich circuit-switched speech calls in mobile telephony. Circuit-switched and packet-switched transmissions generally operate on completely different transmission paths resulting in different QoS in terms of delay and loss rates. In this case, video and audio data recorded at the same time are not multiplexed together...
