Automated estimation of link quality for Lora: A remote sensing approach

Many research and industrial communities are betting on LoRa to provide reliable, long-range communication for the Internet of Things. This new radio technology, however, provides widely heterogeneous coverage; a LoRa link may span hundreds of meters or tens of kilometers, depending on the surrounding environment. This high variability is not...

Do we really need A Priori Link Quality Estimation?

Traditionally, link quality estimation (LQE) has been viewed as an a priori step in sensor network routing protocols because it filters out unreliable links before data transmission. Recent results, however, show that protocols can perform well without a priori LQE. Because getting rid of LQE seems rather counter-intuitive, the aim of this work...

An investigation of link quality assessment for mobile multi-hop and multi-rate wireless networks

Wireless ad hoc networks will be an important component in future communication systems. The performance of wireless ad hoc networks can be improved by link quality-aware applications. Wireless link quality is dynamic in nature, especially in mobile scenarios. Therefore, accurate and fast packet delivery ratio estimation is a prerequisite to...

Impact of wireless link quality across communication layers

Nowadays, wireless networks are used in most of the applications with radio technologies being used in all kinds of wireless networks. In all wireless links, the transmitted packets can be lost. How to identify the quality of a certain wireless link and achieve the best delivery performance over a certain wireless network is an open issue. In...

Transmission Power Adaptation Using Link Quality Estimation In IEEE802.11

Nowadays, energy saving for wireless communication is more important than before. Lots of wireless devices are battery operated, like devices used in WLAN, ad hoc mode, sensor network, cellular network and so on. For example, Ad hoc networks which are composed of these wireless mobile devices can automatically establish peer to peer...
