Background:
Contemporary Wi-Fi networks face significant challenges in signal transmission, especially in environments with dense obstacles or high traffic, where maintaining strong and reliable connections is crucial. Current beamforming methods, which aim to direct wireless signals towards specific users to enhance signal strength and throughput, often rely on predefined algorithms. These algorithms struggle to adapt to dynamic environments and the ever-changing nature of wireless channels, leading to suboptimal network performance, increased interference, and reduced data rates. As user expectations for seamless connectivity rise and the demand for high-speed internet and more connected devices grows, the limitations of these static algorithmic approaches have become increasingly apparent, driving the need for more adaptive and efficient solutions.
Description:
Northeastern researchers have created Sensing-Assisted Wireless Edge Computing (SAWEC), an innovative approach designed to alleviate the computational demands of deep neural networks (DNNs) on mobile devices by optimizing data transmission to wireless edge computing infrastructure. By leveraging environmental knowledge, SAWEC identifies static portions of video frames, eliminating the need to transmit them and focusing only on changes between frames, thereby significantly reducing the data load on wireless networks. This technology employs wireless sensing techniques to pinpoint objects' locations and track environmental dynamics, which results in a sharper decrease in end-to-end latency and computational load compared to traditional wireless edge computing solutions. These advancements make SAWEC a distinct and efficient paradigm for supporting advanced computation on mobile devices without overburdening wireless links. To date, SAWEC has demonstrated its capability to reduce network strain and maintain service quality, showcasing its potential as a transformative solution in real-time data processing applications.
