A Case for Application Aware Channel Access in Wireless Networks

Free registration required

Executive Summary

The increasing reliance of users on wireless networks for Internet connectivity has posed two significant challenges for mobile networking research. The first challenge is to provide high quality of service for interactive real-time applications such as VoIP and video conferencing. The second challenge is to reduce the energy consumption of mobile devices and improve battery life. Past research has focused on separately addressing these seemingly conflicting goals in distributed medium access based wireless networks. Contrary to the traditional tiered networking approach, the authors argue that an application aware approach to medium access and power saving has the potential to significantly improve the performance of real-time applications and conserve battery power on mobile devices.
