In this paper, we propose a time division method to solve the congestion control problem for
an event-driven sensor network. In this method, a node adjusts time (therefore bandwidth) …

Interest in high-altitude platforms (HAPs) has been increasing recently, especially with the
rapid technical development in solar panels' efficiency, energy storage, antenna design, and …

Packet Combining (PC) and Multipacket Reception (MPR) techniques have great potential
to deal with lost packets since both take full advantage of the signals associated to all failed …

Current wireless communication systems rely on the assumptions of the Nyquist theorem.
Faster-Than-Nyquist (FTN) assumes that a bandwidth below the Nyquist bandwidth can be …

Modern broadband wireless systems require high throughputs and can also have very high
Quality-of-Service (QoS) requirements, namely small error rates and short delays. A high …

Num sistema de telecomunica ̧c ̃oes m ́oveis, os canais de propaga ̧c ̃ao multi-percurso
dispersivos no tempo afectam consideravelmente a liga ̧c ̃ao ascendente dacomunica ̧c …

The forthcoming generation of mobile communications, 5G, will settle a new standard for a
larger bandwidth and better Quality of Service (QoS). With the exploding growth rate of user …
