As one of the most popular topics in the Next Generation Network (NGN), Named Data Networking (NDN), a newly proposed network architecture centered on content data, targets on altering the existing communication protocol between Internet hosts. NDN uses data names rather than IP addresses for data transmission and re-designs the packet formats and the protocols between layers in order to substitute...
With the explosion of smartphone popularity in recent years, people are familiar with mobile tourism guides. Users often spend much time to look for travel information on the Internet without user interaction on relevant websites. Generally, the tour guides lead tourists to interact with travel attractions in a group trip. This study applies an interactive model to traveling while tourists join a...
This paper designs a new scheme based on Controlled Vehicular Internet Access (CVIA), a protocol that divides a straight road into several segments. To avoid hidden nodes and reduce unnecessary CTS/RTS, vehicles send the packet to the road side unit (RSU) segment by segment. The features of CVIA include its high end-to-end throughput and fairness between road segments. However, a significant problem...
Nowadays, with the wide establishment of IEEE 802.11, more and more people use Wi-Fi to surf on the Internet. Due to the convenience and mobility of the mobile devices, a number of mobile users have been increasing greatly. For real-time video and VOIP have attracted much attention, the delay time of handoff is the most important issue for the service. In order to provide high-speed service with low...
The number of action devices is currently increasing. If the trade environments are not safe, both the development and the progress of electronic trade will be affected. As well as security issues, the handoff procedure incurs long latency and packet loss. Smooth handoff can not only lower the packet loss but also reduce the level of the out-of-sequence packets. So far, very little attention has been...
