Field measurements of 4G mobile networks

Tackling Bufferbloat in 3G/4G Mobile Networks

With the exponential growth of hand-held devices like smart phones and tablet computers, a deep investigation of TCP performance in cellular networks is becoming increasingly important. In this paper, we conducted extensive measurements over the 3G/4G networks of four major U.S. carriers as well as the largest carrier in Korea and discovered a significant problem: the bufferbloat in cellular ne...

Integration of Mobile Ad Hoc Networks in 4G Networks

This Fourth-generation wireless networks may require an integration of mobile ad hoc networks (MANET) into external network to enhance the flexibility of the communication and roaming. This phenomenon is well-suited for commercial and military applications which yield additional benefit of roaming. However, integration of MANET with external network poses a serious security challenge for commun...

Reconfiguration Management in 4g Mobile Networks: Requirements, Process and Architecture

Global vision consensus on the next generation of wireless mobile communications, broadly termed 4G, sketches a heterogeneous infrastructure, comprising different wireless access systems in a complementary manner and vested with reconfiguration capabilities that will facilitate a more flexible and dynamic adaptation of the wireless network infrastructure to better meet the ever-changing service...

Self-Optimizing Solution for 2G, 3G and 4G Mobile Networks

4G Mobile Communication system

The fourth generation of mobile networks will truly turn the current mobile phone networks, in to end to end IP based networks, couple this with the arrival of IPv6, every device in the world will have a unique IP address, which will allow full IP based communications from a mobile device, right to the core of the internet, and back out again. If 4G is implemented correctly, it will truly harmo...
